You must be able to read most of the letters in this line to get an unrestricted driver's license in most states, including Ohio. One of the best-known graphs associated with vision is the Snellen eye chart, designed by Dutch ophthalmologist Hermann Snellen in 1862 to measure visual acuity, how well you can see at different distances. When performing an eye exam, one eye is covered and asked to read the letters in each row aloud, starting at the top of the chart. For example, if your eyes are very dry and your doctor can't help you solve that problem, both contact lenses and LASIK could be uncomfortable for you.
Near vision problems or other vision and eye health problems may not be detected with the Snellen eye chart alone, so a full eye exam is always recommended. Therefore, a legally blind person needs a distance of two feet to detect letters on a standard eye chart that is 20 feet apart.
