When you work at a computer for any length of time, it’s common to experience eye strain, blurred vision, red eyes and other symptoms of computer vision sindrome (CVS). This is because the visual demands of computer work are unlike those associated with most other activities.
If you’re under age 40, eye strain or blurred vision during computer work may be due to an inability of your eyes to remain accurately focused on your screen or because your eyes have trouble changing focus from your keyboard to your screen and back again for prolonged periods. These focusing problems often are associated with CVS.
If you’re over age 40, the problem may be due to the onset of presbyopia — the normal age-related loss of near focusing ability. This, too, can cause CVS symptoms. What can you do? For starters, have a comprenhesive eye exam to rule out vision problems and update your eyeglasses prescription. Studies show that even small inaccuracies in your prescription lenses can contribute to computer vision problems.*
If your glasses are up-to-date (or you don’t need prescription eyewear for most tasks) and you continue to experience eye discomfort during computer work, consider purchasing customized computer glasses. These special-purpose glasses are prescribed specifically to reduce eye strain and give you the most comfortable vision possible at your computer.
Why Computer Glasses?
Computer glasses differ from regular eyeglasses or reading glasses in a number of ways to optimize your eyesight when viewing your computer screen. Computer screens usually are positioned 20 to 26 inches from the user’s eyes. This is considered the intermediate zone of vision — closer than driving (“distance”) vision, but farther away than reading (“near”) vision.
Most young people wear eyeglasses to correct their distance vision. Reading glasses are prescribed to correct near vision only. A biofocals prescribed for those over age 40 with presbyopia correct only near and far. Even trifocals and progressive lenses (which do have some lens power for intermediate vision) often don’t have a large enough intermediate zone for comfortable computer work.
Without computer eyeglasses, many computer users often end up with blurred vision, eye strain, and headaches — the hallmark symptoms of computer vision syndrome. Worse still, many people try to compensate for their blurred vision by leaning forward, or by tipping their head to look through the bottom portion of their glasses. Both of these actions can result in a sore neck, sore shoulders and a sore back.Though they sometimes are called “computer reading glasses,” it’s best to call eyewear designed specifically for computer use “computer glasses” or “computer eyeglasses” to distinguish them from conventional reading glasses. Computer glasses put the optimum lens power for viewing your computer screen right where you need it for a clear, wide field of view without the need for excessive focusing effort or unhealthful postures.
Bojan Kozomara (Banjaluka, 30. decembra 1978) je doktor medicine, specijalista oftamologije i direktor specijalne oftalmološke bolnice Svjetlost Banja Luka.
U svom rodnom gradu završio je Gimnaziju i Medicinski fakultet, a 2009. godine specijalizovao se za oblast oftamologije. 2016. godine postao je magistar medicinskih nauka iz oblasti oftamologije, a svoju profesiju usavršio je na Klinici za očne bolesti, VMA Beograd, Srbija, te na Klinici Oculistica Universita „Careggi“, u Firenci, Italija. Nakon završene specijalizacije u Italiji, odlučio se vratiti u rodnu Banjaluku i tu pokrenuti privatnu kliniku, koja će za vrlo kratko vrijeme postati popularna i prepoznatljiva u regionu, ali i svijetu.
