Here in Central Florida, 3 out of 4 adults need some type of vision correction, either prescription glasses or contact lenses. But what does 20/20 vision really mean?
20/20 vision is a term to express your visual acuity is normal. The American Optometric Association explains:
If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at that distance. If you have 20/100 vision, it means that you must be as close as 20 feet to see what a person with normal vision can see at 100 feet.
Having 20/20 vision does not necessarily mean you have perfect vision. 20/20 vision only indicates the sharpness or clarity of vision at a distance. Other important vision skills, including peripheral awareness or side vision, eye coordination, depth perception, focusing ability and color vision, contribute to your overall visual ability.
Some people can see well at a distance but are unable to bring nearer objects into focus. This condition can be caused by hyperopia (farsightedness) or presbyopia (loss of focusing ability). Others can see items that are close but cannot see those far away. This condition may be caused by myopia (nearsightedness).
Though you may not be experiencing vision problems, most people don’t even realize they need corrective lenses, it is important to get regular eye exams.
A typical eye exam includes several tests. An eye muscle movement test, examination of the outside and inside the eye, a performance test to see how well your eyes work together, depth perception, color and peripheral vision test, check for abnormal eye pressure as well as how the responsiveness to light.
Most insurance plans cover the cost of a comprehensive eye exam, a pair of prescription glasses, and sometimes contact lenses, depending on the coverage.
Our eyes are our window to the world, and they deserve the best in quality care. Yearly doctor visits are made to ensure overall health, eye exams should follow the same protocol. Lake Nona Eye Care provides eye exams by top optometrist, Dr. Cynthia Physician and Dr. Leticia Sandoval, to ensure you stay on top of your eye health.
