If your eyes feel tired, dry or strained by the end of a workday spent looking at screens, you're describing digital eye strain — one of the most common complaints we hear from customers who work long hours on a computer or phone.
Why Screens Cause This
A few things compound at once: we blink roughly half as often when looking at a screen, which dries the eyes out; screens are typically viewed at a fixed, closer distance for extended periods, which tires the eye's focusing muscles more than the varied distances of a normal day; and small text or poor screen contrast forces the eyes to work harder to resolve detail.
Common Symptoms
Tired or sore eyes by late afternoon, occasional blurred vision when looking up from a screen, headaches concentrated around the eyes or temples, and dry or irritated eyes are all typical. None of these are usually a sign of an eye health problem on their own, but they're worth mentioning at your next eye test regardless.
What Actually Helps
The 20-20-20 rule is genuinely useful and free: every 20 minutes, look at something roughly 20 feet away for 20 seconds, giving your focusing muscles a real break. Deliberately blinking more often during screen work, and keeping screens at arm's length rather than closer, both help too.
Where a Lens Coating Fits In
ZEISS BlueGuard, which we fit at Vision Optique, reduces the amount of blue light transmitted from digital devices — we present this as a comfort option for screen-heavy days, not a cure for digital eye strain on its own, since posture, blink rate and break habits matter just as much.

When It's Worth an Eye Test
If screen-related discomfort is new, worsening, or not improving with the habits above, it's worth having your prescription checked — an outdated prescription makes screen work noticeably more tiring, and is a more common cause of "screen fatigue" than people assume.
