Digital eye strain

Digital Eye Strain


Digital Eye Strain describes a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader and cell phone use. Many individuals experience eye discomfort and vision problems when viewing digital screens for extended periods. The level of discomfort appears to increase with the amount of digital screen use.

The average Nigerian worker spends seven hours a day on the computer either in the office or working from home. To help alleviate digital eye strain, follow the 20-20-20 rule.


The most common symptoms associated with Digital Eye Strain are:

  • eyestrain
  • headaches
  • blurred vision
  • dry eyes
  • neck and shoulder pain

These symptoms may be caused by:

  • poor lighting
  • glare on a digital screen
  • improper viewing distances
  • poor seating posture
  • uncorrected vision problems
  • a combination of these factors

The extent to which individuals experience visual symptoms often depends on the level of their visual abilities and the amount of time spent looking at a digital screen. Uncorrected vision problems like farsightedness and astigmatism inadequate eye focusing or eye coordination abilities, and aging changes of the eyes, such as presbyopia can all contribute to the development of visual symptoms when using a computer or digital screen device.

Many of the visual symptoms experienced by users are only temporary and will decline after stopping computer work or use of the digital device. However, some individuals may experience continued reduced visual abilities, such as blurred distance vision, even after stopping work at a computer. If nothing is done to address the cause of the problem, the symptoms will continue to recur and perhaps worsen with future digital screen use. 

Prevention or reduction of the vision problems associated with Digital Eye Strain involves taking steps to control lighting and glare on the device screen, establishing proper working distances and posture for screen viewing, and assuring that even minor vision problems are properly corrected.

What causes Digital Eye Strain?
Viewing a computer or digital screen often makes the eyes work harder. As a result, the unique characteristics and high visual demands of computer and digital screen device viewing make many individuals susceptible to the development of vision-related symptoms.

Uncorrected vision problems can increase the severity of Digital Eye Strain symptoms.

Viewing a computer or digital screen is different than reading a printed page. Often the letters on the computer or handheld device are not as precise or sharply defined, the level of contrast of the letters to the background is reduced, and the presence of glare and reflections on the screen may make viewing difficult.

Viewing distances and angles used for this type of work are also often different from those commonly used for other reading or writing tasks. As a result, the eye focusing and eye movement requirements for digital screen viewing can place additional demands on the visual system.

In addition, the presence of even minor vision problems can often significantly affect comfort and performance at a computer or while using other digital screen devices. Uncorrected or under corrected vision problems can be major contributing factors to computer-related eyestrain.

Even people who have an eyeglass or contact lens prescription may find it’s not suitable for the specific viewing distances of their computer screen. Some people tilt their heads at odd angles because their glasses aren’t designed for looking at a computer. Or they bend toward the screen in order to see it clearly. Their postures can result in muscle spasms or pain in the neck, shoulder or back.

In most cases, symptoms of Digital Eye Strain occur because the visual demands of the task exceed the visual abilities of the individual to comfortably perform them. At greatest risk for developing Digital Eye Strain are those persons who spend two or more continuous hours at a computer or using a digital screen device every day.

How is  Digital Eye Strain diagnosed?

Digital Eye Strain can be diagnosed through a comprehensive eye examination. Testing, with special emphasis on visual requirements at the computer or digital device working distance, may include:

  • Patient history to determine any symptoms the patient is experiencing and the presence of any general health problems, medications taken, or environmental factors that may be contributing to the symptoms related to computer use.
  • Visual acuity measurements to assess the extent to which vision may be affected.
  • refraction to determine the appropriate lens power needed to compensate for any refractive errors (nearsightedness, farsightedness or astigmatism).
  • Testing how the eyes focus, move and work together. In order to obtain a clear, single image of what is being viewed, the eyes must effectively change focus, move and work in unison. This testing will look for problems that keep your eyes from focusing effectively or make it difficult to use both eyes together.

This testing may be done without the use of eye drops to determine how the eyes respond under normal seeing conditions. In some cases, such as when some of the eyes’ focusing power may be hidden, eye drops may be used. They temporarily keep the eyes from changing focus while testing is done.


Using the information obtained from these tests, along with results of other tests, your optometrist can determine if you have Digital Eye Strain and advise you on treatment options.

How is Digital Eye Strain treated?

Solutions to digital screen-related vision problems are varied. However, they can usually be alleviated by obtaining regular eye care and making changes in how you view the screen.

Eye Care

In some cases, individuals who do not require the use of eyeglasses for other daily activities may benefit from glasses prescribed specifically for computer use. In addition, persons already wearing glasses may find their current prescription does not provide optimal vision for viewing a computer.

  • Eyeglasses or contact lenses prescribed for general use may not be adequate for computer work. Lenses prescribed to meet the unique visual demands of computer viewing may be needed. Special lens designs, lens powers or lens tints or coatings may help to maximize visual abilities and comfort.
  • Some computer users experience problems with eye focusing or eye coordination that can’t be adequately corrected with eyeglasses or contact lenses. A program of vision therapy may be needed to treat these specific problems. Vision therapy, also called visual training, is a structured program of visual activities prescribed to improve visual abilities. It trains the eyes and brain to work together more effectively. These eye exercises help remediate deficiencies in eye movement, eye focusing and eye teaming and reinforce the eye-brain connection. Treatment may include office-based as well as home training procedures.
computer vision syndrome

Viewing the ComputerSome important factors in preventing or reducing the symptoms of Digital Eye Strain have to do with the computer and how it is used. This includes lighting conditions, chair comfort, location of reference materials, position of the monitor, and the use of rest breaks.Location of computer screen – Most people find it more comfortable to view a computer when the eyes are looking downward. Optimally, the computer screen should be 15 to 20 degrees below eye level (about 4 or 5 inches) as measured from the center of the screen and 20 to 28 inches from the eyes.

Reference materials – These materials should be located above the keyboard and below the monitor. If this is not possible, a document holder can be used beside the monitor. The goal is to position the documents so you do not need to move your head to look from the document to the screen.

Lighting – Position the computer screen to avoid glare, particularly from overhead lighting or windows. Use blinds or drapes on windows and replace the light bulbs in desk lamps with bulbs of lower wattage.

Anti-glare screens – If there is no way to minimize glare from light sources, consider using a screen glare filter. These filters decrease the amount of light reflected from the screen.

Seating position – Chairs should be comfortably padded and conform to the body. Chair height should be adjusted so your feet rest flat on the floor. If your chair has arms, they should be adjusted to provide arm support while you are typing. Your wrists shouldn’t rest on the keyboard when typing.

Rest breaks – To prevent eyestrain, try to rest your eyes when using the computer for long periods. Rest your eyes for 15 minutes after two hours of continuous computer use. Also, for every 20 minutes of computer viewing, look into the distance for 20 seconds to allow your eyes a chance to refocus.

Blinking – To minimize your chances of developing dry eyeswhen using a computer, make an effort to blink frequently. Blinking keeps the front surface of your eye moist.

Regularly eye examination and proper viewing habits can help to prevent or reduce the development of the symptoms associated with Digital Eye Strain.

How to Look Sexy in Glasses – and Clearing out Misconceptions About Spectacles

Updated on February 9, 2019

Tips & Tricks To Look Sexy In Glasses for women
Tips & Tricks To Look Sexy In Glasses for women

So the visit to the eye doctor gave you a pair of unwanted spectacles leaving you feeling like you’re on the receiving end of a prison sentence rather than just a prescription. Males and females alike dread being prescribed powered eye glasses for various reasons and the most prominent of them being, their fear of hampering their appearance as it is generally a preconceived notion that their appearance will be negatively affected by wearing eye-glasses. Empirical evidence shows that this has caused many to not even give spectacles a shot and thereby, they ended up causing more harm to their precious eyes. This article will focus on how girls can look gorgeous in glasses while giving their eyes what they need. I cannot stress the importance of wearing powered glasses when prescribed by the eye doctor. Therefore, this article is all about alleviating this groundless presumption as I will show you how to look sexy in glasses.

Gone are the days of ugly and unflattering looking eye glasses which only deteriorated the appearance of the wearer. Eye glasses are now worn by many women not only when they need to wear them but also for fashion purpose. A pair of glasses can in fact be what is needed to add that sexy hint to the look.

Misconception about Glasses:

Hides the beauty of the eyes: Like everything in life, there is a right and a wrong way of wearing glasses. It is a misconception that wearing glasses hides the beauty of the eyes. Big framed glasses can actually accentuate the eyes rather than hiding them. The following photographs of gorgeous girls in eye spectacles will clear this misconception:

What’s your style?

Girls who wear eye glasses cannot show-off their eye makeup:This is utter nonsense! Big round or square or oval shaped glasses can easily and properly show-off beautifully made up eyes. Big framed glasses actually accentuate the eyes in a very becoming way. I personally find that there is only one drawback of wearing glasses and makeup, which is wearing lots of mascara, as the eye lashes keep on touching the glass and that can sometimes be irritating. But hey, a little discomfort is nothing right?

Glasses are boring and nerdy: Nerdy is not always a bad thing. The right amount of “nerdy” is actually sexy, like the school teacher kind of sexy. These bold, thick framed glasses on girls is just too gorgeous for words. To think that wearing glasses would make a girl look boring and nerdy is beyond comprehension. Find below photographs of glasses that girls can wear to look smoking hot in nerdy:

Cat’s eye glasses: Cat lovers and others alike can go for the very smoky hot look that cat’s eye glasses can add to the appearance. Cat’s eye glasses are at the top of my list of eye glass shapes to look sexy. However, these catty reading glass frames are also referred to as librarian glasses. Don a pair of kitty cat glasses with bold red lips and any girl is ready to face anything.

Colourful frames: Who says eye glasses have to be dull and boring. Keep a few colourfully framed glasses to suit different moods and occasions. Some women prefer wearing bright coloured frames on a regular basis. Choose the right type of eye glass frame that makes you feel most comfortable.

So we all know of a handful of common spectacle frame shapes like round shaped reading-glasses, cat’s eye glasses, square shaped specs, etc. But do we actually know what different shapes of frames for eye-wear represent: Check out the what each different shape of frames for glasses reveal about the personalities of the spectacle wearer below:

How to choose the right frame for eye-glasses:

Therefore, depending on the look the lady wants to achieve when wearing her spectacles she can decide on the eye glass frame shape. If the wearer has big eyes and she wants to flaunt her eye colour and frame the eyes in a becoming manner, she should wear large frames, like the 80/s over sized eye-glass frames, so that the view of her eyes are clear and the frames of the glasses frame her eyes keeping considerable distance. If she wants to minimize the presence of the frames as much as possible she can actually go for frame-less eye glass or eye glasses which only has a border on the top. For women wanting to create a bold and sexy look, she should wear thick dark framed specs.

I am sure that after seeing these photographs of women in various shapes of eye-glass frames and how gorgeous and sexy these ladies look wearing glasses the misconception about spectacles have been dispersed.

What type of lens is used to correct nearsightedness?

What Type of Lens Is Used to Correct Nearsightedness?

Nearsightedness — the condition where a person can see near objects clearly but distant vision is blurred — typically is easily corrected with prescription eyeglasses or contact lenses.

Lenses used to correct nearsightedness are concave in shape. In other words, they are thinnest at the center and thicker at the edge.

These lenses are called “minus power lenses” (or “minus lenses”) because they reduce the focusing power of the eye. By doing so, minus lenses move the focus of light in a nearsighted eye from a point in front of the retina backward so it falls directly onto the surface of the retina. This shift corrects the blurry distance vision caused by myopia, restoring clear vision.
The power of lenses that correct nearsightedness is measured in diopters (D) and this power number always begins with a minus sign. The higher the dioptric power of the lens, the more myopia it corrects.

For example, a -6.00 D lens corrects twice the amount of nearsightedness as a -3.00 D lens.

High-index lenses typically are recommended for correcting nearsightedness greater than -3.00 diopters. These lenses are thinner and lighter than standard plastic lenses, making them more attractive and comfortable.

Also, anti-reflective coating is highly recommended for lenses that correct nearsightedness. AR coating eliminates distracting reflections in the lenses, making them appear thinner and more attractive. Eliminating reflections also improves vision and comfort.

Ortho-k contact lenses are another choice for the correction of nearsightedness. These are specially designed rigid gas permeable (GP) contact lenses that not only correct existing myopia — they may actually help control myopia progression in children.

How to wear makeup with glasses

How to wear makeup with glasses?

By Lydia, fashion optometrist

some girls were asking how to make their make up stand out with their glasses on. Probably these are peeps who love make up brand.
Some days you’re simply too tired and barely open your eyes to get your contacts in. That means glasses and no-make up today, right? Wrong! Just because you wear glasses doesn’t mean you have to go bare-faced all the time. There are numerous tricks out there to get your make-up to show from behind your second set of peepers. You need to harness them and use them to your advantage. You might even look sexier since guys find women with glasses smarter (because you know guys like smart girls and all). Do a smokey eye. The style isn’t just for nighttime anymore. The eyes need to be accentuated to stand out from behind your glasses, so dark colors and smudging is a must. Pick a shadow color that will make your irises pop, like green shadow for brown eyes. Use a toned-down lipstick that is a shade similar to your skin color to make your eyes stand out even more.

Bubblegum lips. Although they might not taste like bubblegum, the color looks absolutely delicious. The color gives your face a pop of noticeable color.

Defined brows. Make sure they’re not hiding behind your glasses by accentuating them! Clean them up by tweezing, line your brows with brow liner, and then fill them in with brow pencil. If you don’t own a brow pencil, filling in your eyebrows with brown eye shadow will do the trick.

Neon  eyes. Want to make a statement? This is the ultimate way to draw the eyes away from the glasses and to your actual eyes. Use one electric color on the top lid and a different, bright color on your lower eye. Finish off the look by blending in black in the creases to make the color stand out even more. Mascara isn’t required.

How to Clean the Nose Piece of Your Glasses By Christina Martinez

You already know to clean your lenses regularly, but other parts of your eyeglasses should be cleaned as well. Some eyeglasses have plastic nose pieces that sit on the bridge of your nose. These plastic pieces constantly touch your skin, where they pick up dirt, bacteria and oils. To keep them clean, and to forestall the yellowing that happens on nose pieces with age, you can employ a few cleaning strategies.

Step 1

Remove the nose pieces carefully if you are able to. Some nose pieces are removable with a screwdriver made for eyeglasses; it depends on the frame design. If you do remove the nose pieces, make sure you keep track of screws and any other associated parts.

Step 2

Dust the nose pieces off with a clean, soft cloth to get rid of any excess dirt or grime.

Step 3

Put a bit of mild soap onto a wet, clean, soft-bristled toothbrush. Scrub the nose pieces with the toothbrush. Rinse them clean and dry them with a soft cloth.

Step 4

Dip a cotton swab into rubbing alcohol. Run this over the nose pads to disinfect them. You can do this either while the glasses are still connected to the pads, or after you have removed them.

hope this help

What You Should Know About Choosing Eyeglass Frames


20180528_111641

Choosing a frame for your glasses can be a daunting task, but choosing the right frame is important because eyewear frames can truly enhance your appearance, just as your lenses enhance your vision.

Frames come in a variety of colors, and are of varying durability, weight, and price. There are designer brands and less expensive brands, and some are made of hypoallergenic materials while others are not.

Considering these many options, it is important to find frames that not only suit your style and are fitted to the shape of your face, but are also suited for your prescription and lifestyle. It is important to understand the importance of durability, consistency of finish and manufacturer, company reliability, and style appeal. These qualities are not always found in lesser quality frames or vendors.

You should always consult a professional before choosing a frame. If you have never purchased a pair of glasses, you may not know that there is much more to it than just getting a prescription and picking out your favorite frames.

There are other considerations, such as the shape of your face, your skin tone, your lifestyle needs, lens designs, lens features, etc. Most opticians can assess your prescriptions, face shape, and skin tone without you even knowing they have done so.

When you visit your optician, however, they will ask you a few questions about your lifestyle and fashion needs in order to better help you in choosing the right frame.

Lens Considerations When Choosing a Frame

The first thing your optician will do is review your prescription and ask you a few lifestyle questions. They do this because depending on your individual prescription and needs, you may not be able to choose from all the available frames.

It is important to know that lenses can be made in aspheric or hi-index designs for the more difficult prescription. These designs are made with a much flatter curve, so there is less thickness in the lens, giving the eyewear a slimmer, more flattering profile.

This also makes it possible for someone with a strong prescription to wear a larger selection of frames without worrying that the lenses are too thick and noticeable.

Myopic Prescriptions (nearsighted or minus)

These lenses will be thicker at the edges than in the center. If the prescription is less than -2.50, almost any frame size or shape will be suitable, and the lens will have a cosmetically acceptable edge thickness.

Most of today’s fashionable frames are made of plastic or metal with rims thinner than the lens itself. Also popular are rimless mountings that leave the lens edge completely exposed.

For prescriptions over -2.50 a smaller frame should be considered to avoid edge thickness, and when choosing a rimless mounting, high-index lenses should be used.

Hyperopic Prescriptions (farsighted or plus)

These lenses will be thicker in the center. The stronger the prescription, the heavier and more uncomfortable the lens will become for the wearer. The centers of these lenses will also appear to bulge out from the frame.

As with myopic prescriptions, powers less than +2.50 will be able to choose from a larger selection of frames. It is important to remember that thin or rimless frames may not be suitable for these lenses because the edge is the thinnest portion and cannot always be securely fitted into the frame.

Choosing a smaller, sturdier frame will decrease the heaviness of the lenses, making your glasses more comfortable. Also, having adjustable nose pads rather than fixed makes adjustments easier and keeps the heavy lenses sitting in the correct position.

Progressive Lenses (no-line)

Progressive lenses are aspheric by design. A progressive lens is a lens that transitions in power as the eye moves vertically. The reading area is located in the bottom portion of the lens, making it important to choose a frame large enough to have sufficient viewing areas at all distances.

When a frame that is too small for a progressive design is chosen, the reading area will end up being uncomfortably small or unusable.

Lens manufacturers have overcome this problem by introducing “short corridor” progressive lenses with a more compact design that provides larger reading areas for today’s smaller, fashionable frames.

Other Considerations When Choosing a Frame

Eyewear should emphasize your best personal feature, complimenting the shape and coloring of your face. They should fit properly to be comfortable, but also allow you to see through the lenses at the optical center for optimal vision.

Face Shape Considerations:

Round: A round face has curved lines with the width and length in the same proportions and no angles. To make a round face appear thinner and longer, try angular narrow frames to lengthen the face, a clear bridge to widen the eyes, and frames that are wider than they are deep, such as a rectangular shape.

Oval: To keep the oval’s natural balance, look for frames that are as wide as the broadest part of the face, or walnut-shaped frames that are not too deep or too narrow.

Oblong: An oblong face is longer than it is wide and has a long, straight cheek line and sometimes a longish nose. To make the face appear shorter and more balanced, try frames that have more depth than width, decorative or contrasting temples that add width to the face, or a low bridge to shorten the nose.

Base-Down Triangle: A base-down triangular face has a narrow forehead and widens at the cheek and chin areas. To add width and emphasize the narrow upper third of the face, try frames that are heavily accented with color and detailing on the top half, or cat-eyed shapes.

Base-Up Triangle: This face has a very wide top third and a small bottom third. To minimize the width of the top of the face, try frames that are wider at the bottom and are made of very light colors and materials, or rimless frame styles.

Diamond: Diamond-shaped faces are narrow at the eye line and jaw line, and have broad cheekbones that may be high and dramatic. This is the rarest face shape. To highlight the eyes and soften the cheekbones, try frames that have detailing or distinctive brow lines, or try rimless frames or oval shapes.

Square: A square face has a strong jawline and a broad forehead, plus the width and length are in the same proportions. To make the square face look longer and soften the angles, try narrow frame styles, frames that have more width than depth, and narrow ovals.

Color Tone Considerations:

Skin, eyes, and hair have color bases that fall into two categories: cool tone or warm tone. Cool has blue or pink undertones and warm has peach or yellow. Olive skin is considered cool because it is a mixture of blue and yellow.

Brown eyes can vary from light amber, a warm tone, to medium brown-black, a cool tone. Sixty percent of Americans have cool toned skin. Some examples of frame colors best suited for these tones are below:

Cool Tones: Black, rose-brown, blue-gray, plum, magenta, pink, jade, blue, and darker tortoise.

Warm Tones: Camel, khaki, gold, copper, peach, orange, coral, off-white, fire red, warm blue, and blond tortoise.

Frame Styles:

There are many types of frames but these are the most common:

Full Frame: Composed of plastic or metal materials, and has a rim that surrounds the lenses entirely.

Semi-Rimless (or grooved rimless): Composed of metal or a combination of both plastic temples and metal frame front. The lenses are only partially surrounded by metal and held in place with a nylon cord, usually on the bottom portion of the lenses.

Rimless (or drilled rimless): Composed of only three metal parts, two temples and one bridge. The glasses are assembled by drilling two sets of holes in each lens and attaching the temples and bridge directly into these holes. The lenses are not surrounded by material at all.

Materials:

Plastic: Plastic frames are lightweight and come in an array of color options. Zyl is the most common plastic frame material; it is nylon based and hypoallergenic. Nylon can be easily molded for the more popular wrap styles.

A drawback to plastic frames is they need special care when warming during adjustments because they can easily pit, and the finish can be damaged if overheated. They are more easily broken than metal frames, and exposure to sunlight decreases their strength slightly.

Color can fade over time, but this happens less with premium manufactures. They will burn, but are not easily ignited.

General Metals: Most frames in the US are made of metal. Some metals can react with skin chemistry, but this is preventable by using metals that are palladium or nickel-free. Monel is the most common metal frame material because it resists corrosion.

Beryllium is also popular because it also resists corrosion and tarnish, making it an excellent choice for wearers who have high skin acidity or spend a lot of time in or around salt water.

Titanium is extremely lightweight and will not rust, and because of its strength it can be made thin. It has been used for everything from the Gemini and Apollo space capsules to medical implants such as heart valves. Titanium can be produced in a variety of colors and is hypoallergenic.

Flexon is a titanium-based alloy. This unique and popular material, invented by the frame manufacturer Marchon, is called a “memory metal,” meaning that the frames come back into shape even after twisting, bending, and crushing. They are 25% lighter than standard metals, hypoallergenic and corrosion-resistant.

Accents:

Wood, Bone, and Horn: Although less adjustable and much more expensive than other accents, this material is appealing because of its unique beauty.

Leather: Leather is not as durable as other accents, but it provides an interesting and fashionable look.

Semi-Precious or Precious stones and Rhinestones: Popular choices are onyx, turquoise, and Swarovski crystals, but even diamonds can be used for a luxurious touch. Rhinestones are less expensive and often create a flashy or retro look.
