As many as three out of four people sitting in front of computers or similar video screens for long periods of time could be suffering from so-called dry eye, a syndrome that can impair vision in severe cases, a recent study showed.
Of 1,025 adult Japanese office workers studied by the Japan Ophthalmologists Association, 31.2 percent had dry, bloodshot or worn-out eyes, a report issued by the professional group says. Another 43.8 percent showed signs of developing the condition.
Workers surveyed were staring at computer screens for an average of 5.2 hours a day, and the report blames the long hours for contributing to their eye fatigue.
