Computer Glasses

Today, people are spending more and more of their time in front of computer screens – and don’t think their eyes haven’t noticed.

Computer GlassesIn terms of eye health, the effects of prolonged computer use are very real: dry eyes, blurry or dull vision, eye fatigue, and headaches are among the key symptoms of computer eyestrain, also known as computer vision syndrome (CVS).

One of the more common ways of dealing with this problem is through the use of computer glasses. Computer glasses are specially designed (and prescribed) to address the symptoms associated with computer vision syndrome.

How Computer Glasses Work

When a person uses the computer, the screen is typically 20-26 inches away from their eyes. Computer glasses are specifically designed with this distance in mind – the modified lens power makes it so your eyes don’t have to strain to see the screen, allowing for comfortable and clear vision.

Considering how many hours we spend at the computer every day, making sure your eyes are comfortable can go a long way toward keeping them healthy and strong.

Types of Lenses

There are a number of different special purpose lens designs that can optimize your computer eyewear.

Single vision lenses are the most straightforward choice for computer glasses. Since the entire lens is at the same power, single vision computer glasses offer the largest field of view; but, as a result, they won’t be effective for near and far vision. These are appropriate for computer users of any age.

Occupational progressive lenses are multifocal lenses that are designed for all three types of vision -near, intermediate, and far. However, since the intermediate zone is larger – to improve your view of the computer – there isn’t much area on the lens for distance vision; for this reason, these types of glasses shouldn’t be used for tasks that require you to see far away, such as driving.

There are also occupational bifocal and trifocal lenses, which have more lens area for near and intermediate vision; the exact position of these areas can be adjusted to fit the way you use your computer.

Other Features of Computer Glasses

Certain additional features can be added to your computer glasses for maximum viewing comfort.

  • Computer glasses can be tinted to assist your eyes with focusing on the characters on the screen, and to help cut down on glare. They also filter out certain spectrums of light – such as the “blue” light emitted from computer screens – that have been known to cause discomfort for computer users.
  • Anti-reflective coating reduces the amount of glare coming from the computer screen and nearby light sources. This coating is applied to both the front and back surfaces of your eyeglasses.

Getting a Prescription

Although it’s tempting to think that over-the-counter reading glasses will be fine for computer use, that is not the case.

Prescribed lenses from a certified optometrist or ophthalmologist are needed to ensure that your eyes are as comfortable as possible during computer usage. Otherwise, you risk suffering from eyestrain and related symptoms related to computer vision.

It’s also important to tell your eye doctor how your work area is arranged, so that he or she can prescribe computer glasses that are ideally suited to your situation, and the ergonomics of your office. That’s why, before your appointment, it’s a good idea to measure the distance between your monitor and your eyes.
