Our optometrists in Clarksville and Franklin offers several different vision tests for assessing athletic performance and capabilities. The first test is the classic Snellen Eye Chart. Patients are asked to read lettering on a standard eye chart that is placed 20 feet away. You must identify the letters along the lines of increasingly smaller sizes until the letters can no longer be identified. Usually the 20/20 line is the fourth from the bottom; if you can correctly read this line, you have 20/20 vision. If you can read the smallest line, then you have 20/15 vision. This basic eye test is very important for identifying an athlete’s visual acuity.
While correcting visual acuity can seem like an obvious step, some athletes are unaware that they suffer from an undetected refractive error. Refractive errors are any number of different size and shape abnormalities that affect the eye’s ability to focus light on the retina, affecting vision.
Contrast sensitivity is also important for athletic performance. During a contrast sensitivity test, you will be asked to identify the orientation of parallel gray stripes against backgrounds of various colors. The backgrounds gradually begin to match the shades of the stripes. Low contrast sensitivity, especially in low-light conditions, will make it more difficult to track objects. A variety of solutions can be effective for addressing contrast sensitivity concerns. These solutions include wearing eyeglasses with a special lens tint to increase visibility, depending on your vision needs.
Ocular alignment tests, like the Hirschberg test, evaluate how well both eyes work together. Alignment problems are detected by analyzing specific points on the cornea where reflections occur. Dr. Calvert also recommends eye dominance tests. Our optometrists also recommend eye dominance tests. If one eye loses focus too soon, you may be suffering from binocularity, a condition where both eyes struggle to work together to manage depth perception and visual coordination.
Athletic performance is not only enhanced in the gym; it also requires excellent visual processing speed and hand-eye coordination.
