Computer glasses are specialized lenses designed for intermediate and near viewing distances, typically 20 to 26 inches, which is the distance to a computer screen. They differ from reading glasses and distance glasses by targeting this specific intermediate focus range.

Computer glasses eliminate the need for this constant muscular adjustment, providing a wide field of clear vision at the arm's-length distance.
Standard progressive lenses have three zones, but the intermediate zone is narrow. Computer glasses use a wider, custom intermediate zone that is optimized for the screen. They often lack a strong distance correction at the top, focusing solely on the work area.
Computer lenses are highly recommended with an anti-reflective (AR) coating. The AR coating minimizes glare from the screen and overhead lighting reflecting off the lens surfaces, which further reduces eye fatigue during long sessions.
Computer glasses provide targeted relief from digital strain. This is particularly helpful for contact lens wearers, as digital strain often reduces the blink rate and causes contact lens dryness. Using computer glasses gives eyes a necessary break from both focusing and dryness.
Reading glasses are set for a much closer distance (14 inches). Using them for a computer screen (26 inches) often causes forward leaning or blur.
Computer glasses correct focus (power). Blue light glasses only filter a light spectrum. The best solution often combines both features.
No, since they are focused for an intermediate distance, they will make distant objects look blurry.
If you have "Computer Vision Syndrome" (eye strain, neck pain, blurred vision), see your doctor. A specific intermediate-distance prescription can drastically reduce the physical strain on your eyes and neck muscles during work hours.
