Experts from the American Academy of Ophthalmology note that choosing glasses over contact lenses while spending long hours in front of a computer can help reduce the sensation of dry eyes. To create a simpler, more comfortable setup, they also suggest dialing down the brightness of lights around the workstation and letting the screen sit in a calmer, diffused lighting environment. These small adjustments can make daily screen use more pleasant for many people in Canada and the United States. [Citation: AAO]
Daniel Porter, who oversees patient education about treatment at the American Academy of Ophthalmology, explains that blue light from screens does not heighten eye fatigue. Because of this, wearing special blue-blocking glasses is not a necessity for everyone. Still, it is true that using screens for long periods can lead to dry eyes and headaches for some people.

Dry eye symptoms often appear when people focus intently on a screen and blink less than their normal rate. The typical blink rate sits around 15 blinks per minute, but intense screen work can nearly halve that frequency. Experts recommend using moisturizing eye drops to keep the surface of the eye lubricated and to ease fatigue. If someone expects to work at a computer for extended stretches, a shift away from contact lenses toward glasses can help maintain comfort and reduce eye strain over time. [Citation: AAO]
There are practical routines that can help prevent strain. A well-known technique is the 20-20-20 rule: every 20 minutes, shift attention away from the screen and focus on an object about 20 feet away for 20 seconds. This simple habit gives the eyes a quick reset, which can lessen fatigue and improve concentration. Another effective tactic is to reduce the light from nearby sources and prefer softer, diffused illumination around the device. When the workspace feels overlit or harsh, working in a more gentle lighting balance can enhance comfort and productivity. [Citation: AAO]
Beyond these tips, recognizing symptoms early is important. If persistent dryness or irritation occurs, consulting an eye care professional can help identify underlying causes and tailor a plan that suits individual needs. Routine eye exams remain a cornerstone of maintaining comfort and clear vision during computer use. [Citation: AAO]
