Blue Light and Computer Vision Syndrome

Squinting at computer, tablet, or mobile screens for hours at a time is a normal part of our lives in the 21st century. Unfortunately, eye problems associated with this activity are also on the rise. Even if you have never had eye problems before, you may have noticed computer vision syndrome symptoms after two or more hours of screen time.

Diagnosis of Computer Vision Syndrome

The severity and length of computer vision syndrome symptoms depends on how long you stare at the computer, your posture, lighting, glare, the angle of the monitor, and whether or not you have other diagnosed or undiagnosed vision problems. If you already suffer from astigmatism, farsightedness, presbyopia, aging eyes, and/or diabetic eye problems, your computer vision symptoms may worsen. This can even be the case if you already have prescription contacts or glasses. Many regular eyeglasses and contact lenses are not designed to deflect the problems caused by computer screens.

Signs include:
-Blurry vision
-Eye strain and discomfort
-Headaches
-Dry, scratchy eyes
-Neck and/or shoulder pain

Even if your symptoms are mild, they can worsen and cause other vision problems if not addressed. Our optometrists can help.

We will take your symptoms, pre-existing conditions, and potential undiagnosed conditions into account as we perform the following eye tests:

Visual acuity—Measures the quality of your current vision.

Refraction—Tests the potential lens prescriptions that would optimize your vision.

Focus and Eye Coordination—Tests how well your eyes work together and how quickly and accurately your eyes are able to focus on objects and varying distances.

Treatment Plan

From these details, we can design a treatment plan to help relieve your symptoms. For people with otherwise normal eyes and vision, a set of specially-designed glasses used during the time you are working on the computer can be very helpful.

At Lifetime Eyecare, we use specialty lenses that block blue light emissions to help offset some of the UV damage and strain to your vision. Lenses like the Essilor Eyezen lens also have a small add power at the bottom of the lens to help your eye muscles as they scan different distances (such as the viewing area between your keyboard and your computer screen).

In addition to the Eyezen lenses, many of our progressive lens options have built-in blue blocking filters. Transitions lenses (especially brown) and other non-glare coatings have blue-blocking properties that can enhance the protection in whatever lens options you choose.

At-Home Treatment

For patients already wearing contacts or glasses, new, more computer-friendly lenses are available. In addition to these treatment options, there are many things we can suggest to cut down on computer eye strain problems, like:

  1. Computer SetupAdjust your monitor so that it is about 15-20 degrees lower than your eye level when seated between 20-28 inches away from the screen. Reference materials can be placed on a document holder between the monitor and keyboard, or to the side, but positioned for as little head movement as possible. Also invest in an anti-glare screen for your monitor to help reduce glare from surrounding lights. Be sure to sit and work with proper posture.
  2. Adjust LightingIf you can, reposition any lighting (or your computer) to minimize glare and use natural lighting whenever possible.
  3. Eye Rest and Blinking BreaksEvery 20 minutes during your work, look away toward a distant point for 20 seconds to refocus your eyes, and give them a 15-minute break after each 2-hour computer session. Also remember to blink more frequently and/or use approved eye drops to keep your eyes moist.
