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 needs of computer work are unlike those connected with many other activities.
Do I Need Glasses for Computer Use?
If you’re under age 40, eye strain or blurred vision during computer work might be due to an inability of your eyes to stay accurately focused on your screen or because your eyes have difficulty changing focus from your keyboard to your screen and back once again for prolonged durations. These focusing (lodging) issues typically are related to CVS.
If you’re over age 40, the issue may be due to the start of presbyopia– the typical age-related loss of near focusing capability. This, too, can cause CVS symptoms.
What can you do? For beginners, have a detailed eye exam to eliminate vision issues and upgrade your eyeglasses prescription. Studies show that even small mistakes in your prescription lenses can add to computer vision issues.
If your glasses are current (or you don’t need prescription eyewear for the majority of jobs) and you continue to experience eye pain during computer work, think about buying customized computer glasses. These special-purpose glasses are recommended specifically to decrease eye strain and give you the most comfortable vision possible at your computer.
According to the Vision Council, more than two thirds of us experience Computer Vision Syndrome (CVS). The cause is too much time in front of digital screens, and the symptoms consist of dry or red eyes, blurred vision, eye twitches, tiredness, headaches, and even back and neck pain.
Why Computer Glasses?
Computer glasses vary from routine spectacles or reading glasses in a variety of ways to optimize your eyesight when seeing your computer screen.
Computer screens normally are positioned 20 to 26 inches from the user’s eyes. This is thought about the intermediate zone of vision– closer than owning (” distance”) vision, however farther away than reading (“near”) vision.
A lot of young people wear spectacles to fix their distance vision. Reading glasses are recommended to correct near vision just. And bifocals prescribed for those over age 40 with presbyopia proper only near and far. Even trifocals and progressive lenses (which do have some lens power for intermediate vision) frequently don’t have a large sufficient intermediate zone for comfortable computer work.
Without computer spectacles, many computer users frequently end up with blurred vision, eye strain, and headaches– the trademark symptoms of computer vision syndrome. Even worse still, lots of people try to compensate for their blurred vision by leaning forward, or by tipping their go to check out the bottom portion of their glasses. Both of these actions can result in a sore neck, sore shoulders and a sore back.
Though they in some cases are called “computer reading glasses,” it’s best to call glasses created specifically for computer use “computer glasses” to differentiate them from traditional reading glasses. Proper glasses put the maximum lens power for seeing your computer screen right where you require it for a clear, broad field of view without the requirement for excessive focusing effort or unhealthful postures.
Lens Styles For Computer Eyewear
Many special purpose lens styles work well for computer glasses. Since these lenses are recommended specifically for computer use, they are not appropriate for driving or general function wear.
The most basic computer glasses have single vision lenses with a modified lens power prescribed to give the most comfy vision at the user’s computer screen. This lens power unwinds the quantity of lodging required to keep items in focus at the range of the computer screen and provides the biggest field of view.
Single vision computer glasses minimize the risk of eye strain, blurred vision and abnormal posture that can cause neck and back pain, and can be used conveniently by young and old computer users alike.
Another popular lens design for computer glasses is the occupational progressive lens– a no-line multifocal that corrects near, intermediate, and, as much as a point, distance vision.
It has a bigger intermediate zone than routine progressive lenses, for more comfortable vision at the computer. However this leaves less lens area for distance vision. So these lenses are not advised for owning or other considerable range vision tasks.
Other lenses used for computer glasses include occupational bifocal and trifocal lenses. These lined multifocal lenses have larger zones for intermediate and near vision than routine bifocals and trifocals, and the position of the intermediate and near zones can be tailored for your particular computer vision requirements.
Your eye doctor or ophthalmologist can assist you decide which lens style will best suit your requirements for computer glasses.
Lens Coatings And Tints
For maximum seeing convenience, the lenses of your computer glasses ought to include anti-reflective coating. Often called anti-glare treatment, anti-reflective (AR) finishes eliminate reflections of light from the front and back surfaces of your lenses that can cause eye strain.
Some optometrist advise adding a light tint to computer glasses to reduce glare triggered by severe overhead lighting and to enhance contrast. Tinted computer lenses also are recommended to block short-wavelength, “blue” light produced from computer screens that is connected with glare and eye strain.
For more details about anti-reflective coating and tints for your computer glasses, consult your eye care professional.
Where To Buy Computer Glasses
Resist the temptation to purchase non-prescription reading glasses for use as computer glasses.
Due to the fact that an accurate glasses prescription is vital if you want to get the full gain from computer glasses, it’s best to buy this eyewear from a knowledgeable eye care expert.
Prior to scheduling your eye test, determine how far you want to sit from your computer. Measure from the bridge of your nose to the surface of your computer screen.
Bring this measurement with you to your examination so your optometrist can use it to help identify the optimum lens power for your computer glasses.
