Because so many computer users wear contact lenses, researchers in Spain recently reviewed published studies to see if contact lens wear increases the risk of computer vision problems or causes a worsening of computer vision syndrome.
The investigators found 114 studies written in English or Spanish and published from 2003 to 2013 that referenced both contact lenses and computer use. They chose six studies for final analysis.
All six revealed that contact lens wearers were more likely to have computer vision syndrome symptoms than individuals who wore eyeglasses only or did not need corrective lenses. Prevalence of symptoms ranged from 17 to 95 percent among contact lens wearers and 10 to 58 percent among non-wearers. Also, contact lens wearers were four times more likely to have dry eyes during or after computer use, compared with non-wearers.
A report of the study was published in the March/April 2014 issue of the journal Revista Espanola de Salud Publica.
