EyeXam iPhone App Provides Eye Tests

SAN FRANCISCO, June 2010 — EyeXam is a free iPhone app that you can use to test your eyes. Developed by two optometrists and distributed by Global EyeVentures, the application is designed to test visual acuity at distance and near, as well as the ability to distinguish colors.

It also offers an Amsler grid, which helps you find possible blind spots in your visual field, a test to help you find your dominant eye and an astigmatism test. An included eye exercise is designed to help you improve your ability to converge your eyes. And an eye alignment test checks whether your eyes tend to posture outward, inward or normally.
Of course, EyeXam is mostly an educational tool that cannot replace a comprehensive eye exam. But the tests can alert you to a vision problem you might not have noticed before that should be brought up with your eye doctor. If you don't have an eye doctor, you can find one through the application.
During the first month it was available on the Apple iTunes store, EyeXam was downloaded more than 100,000 times and was the second-most downloaded free iPhone application in the medical category
