Accommodative state in computer users: optometric management

Abstract

At present time there has been an increase of patients making near vision activities with a great near vision demand in reading and computer activities. The clinical practice experience shows frequently that near working for long time in computer generates different symptoms that decrease visual comfort (Lovasik & Kergoat, 1988; Hayes, et ál., 2007). The most frequent associated symptoms related to computer work have been migraine, fatigue, astenopía, jump of lines, intermittent double vision, accommodation problems during the work and after work when patient tries to focus in far vision (Sterner, 2006; Iribarren, 2002; Sheedy & Parsons, 1990); according to the studies, they can be other related causes to a decrease in accommodative response tests: amplitude, accommodative response, flexibility, near point and relative accommodations (Bar et ál., 2000). It also been found that abnormal vergences states that can be associated to accommodative anomalies inasmuch as they maintain one narrow relation, but that can be surpassed with an integral treatment with certain procedures that in the research have shown to be efficient.
