These days most of us spend a lot of time viewing digital devices. When your eyes view the images and words on the screen, they have more difficulty focussing than when you read printed material. This added effort of reading digital devices can cause strain on your eyes. Can glasses help eye strain?
Do You Have Digital Eye Strain?
Eye strain happens when you use your eyes for an extended period of time without taking a significant break. In particular, eye strain occurs when you’ve been staring at the computer screen for too long. Although strain on your eyes isn’t dangerous, it can be annoying and uncomfortable, causing dry and tired eyes.
One of the things that happens when you stare at the screen too long is that your eyes don’t blink as often as they should, causing the ocular surface of your eye to dry out. Your eyes can become tired and irritated. As well, intense concentration on the screen to see better can cause the muscles on your face to clench and tighten. This can disrupt your ability to concentrate when you need to work. You may find yourself squinting and having trouble focusing on the words and images.
Symptoms of Eye Strain
- Blurred vision
- Dry eyes
- Tired eyes
- Red eyes
Computer eyewear can be worn to make it easier for your eyes to read the screen. Lenses used in computer glasses eliminate the need for your eyes to constantly refocus on images and words.
Computer lenses can also reduce vision fatigue by limiting levels of blue light from the screen. Anti-reflective glasses are another good choice for relieving eye strain.
How to Choose Computer Eyewear
There are several different lens types to choose from when it comes to computer eyewear. Be sure to discuss your options with your optometrist.
Single Vision Lenses
Single vision lenses are ideal if you only use glasses occasionally for reading or driving. Single vision computer lenses have the biggest area of unlined clarity than all lens types, making them a good choice for computer work.
Occupational Progressive Lenses
Progressive lenses for the computer allow for a section of the lens to be used primarily for viewing the screen. The section is located at the top of the lens and allows for an increase in magnification to the bottom of the lens to give you close-up vision. Occupational progressive computer lenses are a good choice for a second pair of eyeglasses that you only use when working on the computer
Occupational Bifocal and Trifocal Lenses
Occupational lenses are designed for working on the computer or for doing other work that requires sharp focus. Bifocals and trifocals allow you to look up at the screen and back down again with minimal eye movement.
Tips for Reducing Eye Strain
Most people over the age of 40 can benefit from having more than one pair of eyeglasses. Having at least one pair of occupational eyewear will help minimize eye strain no matter whether you’re reading, watching television, or working on the computer.
Using glasses can significantly ease and prevent eye strain. Your accuracy and productivity in front of the computer will improve the less tired and irritable your eyes are.
