The building blocks of effective sports vision are visual acuity and contrast sensitivity. Proper measurement of these spatial vision attributes is necessary for repeatability in the clinic or in the laboratory. The most repeatable method of testing visual acuity is with logMAR charts—either the Bailey–Lovie chart or the Early Treatment Diabetic Retinopathy Study chart. The Pelli–Robson and the Mars are the most repeatable contrast sensitivity tests.
Athletes may or may not demonstrate superior visual acuity and contrast sensitivity compared with age-matched nonathlete populations, and the optical quality of their eyes may be similar. Dynamic visual acuity in athletes and their performance are typically superior to those of nonathletes.
This lecture will cover factors influencing visual acuity and contrast sensitivity, how visual acuity and contrast sensitivity relate to sports performance, and the best ways to measure visual acuity and contrast sensitivity.
Mark Bullimore is an internationally renowned scientist, speaker, and educator based in Boulder, Colorado. He received his Optometry degree and PhD in Vision Science from Aston University in Birmingham, England. He spent most of his career at the Ohio State University and the University of California at Berkeley and is now Adjunct Professor at the University of Houston. He is Associate Editor of Ophthalmic and Physiological Optics and the former Editor of Optometry and Vision Science. His expertise in myopia, contact lenses, low vision, presbyopia, and refractive surgery means that he is consultant for a number of ophthalmic, surgical, and pharmaceutical companies. This work has resulted in approval of, among others, Paragon CRT, Alcon’s iLux, and CooperVision’s MiSight lens.
