The Orange County Register (10/26, Haas) reported, “Smartphones and similar devices might cause vision concerns,” Dr. Roger Phelps, spokesman for VSP Vision Care, explained. In fact, “according to recent research with VSP eye doctors, 33 percent” of respondents “reported that nearly one-third or more of their patients suffer from digital device-related vision problems. The most common include eye strain (82 percent), dry or irritated eyes (74 percent), fatigue (70 percent) and headaches (61 percent).” Dr. Phelps recommended that people using such devices take frequent breaks, get computer vision glasses, and undergo regular eye examinations.
