Health care: Visual Fatigue

An alert is raised by new studies founding that increased use of small devices (cell phone, PDAs , laptops, game players, ..) may contribute to increased visual fatigue, with pains such as headaches, eyestrain, blurred vision, dry and irritated eyes, and sensitivity to light. The problem was several years ago identified with the use of computer screens, but is exacerbated by the tiny size of the device screen. More than 14% of US optometrist patients have eye or vision-related symptoms resulting from working/ playing on screens.
