The Impact of 3-D on Vision
With the recent boom in 3-D movies, this technology’s impact on the eyes has gotten renewed attention. Although there are no long-term studies, ophthalmologists (MDs) say there is no reason to be concerned that 3-D movies, TV or video games will damage the eyes or visual system.
Some people, however, complain of headaches or motion sickness when viewing 3-D. This may indicate that the viewer has a problem with focusing or depth perception. Also, the techniques used to create the 3-D effect can confuse or overload the brain, causing some people discomfort even if they have normal vision. Taking a break from viewing usually relieves the discomfort. If discomfort persists, you should see your eye doctor, as the symptoms may be caused by an undiagnosed vision problem.
Just as experiencing discomfort while viewing 3-D films and games can sometimes be a symptom of other problems, eyestrain during computer use can be related to other conditions. If you frequently experience dry or tired eyes while working on the computer, you might want to evaluate sleep habits or contact lens use, which can contribute to computer-related eyestrain.
Sleep Deprivation and Your Eyes
When you get less sleep than you need, your eyes may become irritated. Sleep provides an important opportunity for our eyes to rest for an extended period. It’s also a chance for the eyes to be replenished by nutrients. Ongoing eye irritation can lead to swelling and infection, especially if you wear contact lenses.
