If you spend any amount of time working on a computer to doing things on your electronic devices like a tablet or smartphone, you may find that your eyes get tired or blurry after a while. This is because the light that comes from these screens makes your eyes work harder to see the contrast. This light is often called “blue light” and it can be very hard on your eyes. Experts recommend giving your eyes a break ever so often, such as using the 20-20-20 Rule or just walking away for a while.
People who are sensitive to light are usually more susceptible, but even people who don’t have any problem with light sensitivity will feel the effects after prolonged use. This can lead to migraines, headaches, watery eyes, and other discomforts.
Computer glasses have a special anti-reflective coating or tint that blocks the blue light, lessening the strain on your eyes. They can be prescription or non-prescription. Many types have a special tinting that cuts the glare while increasing the contrast. These precision tinted lenses can help prevent headaches and migraines associated with computer use.
Computer Glasses vs Reading Glasses:
Computer glasses are not recommended for reading and reading glasses are not usually recommended for using a computer. This is mainly because your computer screen is several inches away from your eyes, while a book is usually much closer. Add to that the blue light emitted by the computer screen and you have two environments that are quite different and using the glasses in ways they weren’t meant to be used can lead to eye strain.
Choosing prescription glasses with blue-blocking tint will make your experience on the computer much more enjoyable while readers can reduce eye strain when you are reading books or physical documents. If you have light sensitivity, glasses with tinted prescription lenses like Axon Optics’ migraine glasses can help. They may also double as readers or computer glasses.
An eye exam is typically the first step in determining what type of glasses you need. It will identify any problems you may have with your eyes, plus it will ensure that you get the exact magnification that you need.
When you work at a computer for any length of time, it's common to experience eye strain, blurred vision, red eyes and other symptoms of computer vision syndrome (CVS). This is because the visual demands of computer work are unlike those associated with most other activities.
If you're under age 40, eye strain or blurred vision during computer work may be due to an inability of your eyes to remain accurately focused on your screen or because your eyes have trouble changing focus from your keyboard to your screen and back again for prolonged periods. These focusing (accommodation) problems often are associated with CVS. If you're over age 40, the problem may be due to the onset of presbyopia — the normal age-related loss of near focusing ability. This, too, can cause CVS symptoms.
What can you do? For starters, have a comprehensive eye exam to rule out vision problems and update your eyeglasses prescription. Studies show that even small inaccuracies in your prescription lenses can contribute to computer vision problems.
If your glasses are up-to-date (or you don't need prescription EYE WEAR for most tasks) and you continue to experience eye discomfort during computer work, consider purchasing customized computer glasses. These Special Computer Glasses are prescribed specifically to reduce eye strain and give you the most comfortable vision possible at your computer
Lens designs for computer EYE-WEAR:
Many special-purpose lens designs work well for computer glasses. Because these lenses are prescribed specifically for computer use, they are not suitable for driving or general purpose wear.
Computer vision syndrome causes eye fatigue, which can make you feel tired in general.
The simplest computer glasses have single vision lenses with a modified lens power prescribed to give the most comfortable vision at the user's computer screen. This lens power relaxes the amount of accommodation required to keep objects in focus at the distance of the computer screen and provides the largest field of view.
Single vision computer glasses reduce the risk of eye strain, blurred vision and unnatural posture that can cause neck and back pain, and can be used comfortably by young and old computer users alike.
Another popular lens design for computer glasses is the occupational progressive lens — a no-line multi-focal that corrects near, intermediate, and, up to a point, distance vision.
Occupational progressive lenses have a larger intermediate zone than regular progressive lenses for a more comfortable vision at the computer. But this leaves less lens area for distance vision, so these lenses are not recommended for driving or other significant distance vision tasks.
Other lenses used for computer glasses include occupational bifocal and trifocals lenses. These lined multi-focal lenses have larger zones for intermediate and near vision than regular bifocals and trifocals, and the position of the intermediate and near zones can be customized for your particular computer vision needs.
Your optometrist or ophthalmologist can help you decide which lens design will best suit your needs for computer glasses. Now after reading this you have come to know that you need Special Computer Glasses or not.
