Abstract:

Accommodative facility refers to the speed in which the eye is able to change focus from one distance to another. Tennis is a dynamic sport in which the targets are focused at different distances. Therefore accommodative facility in tennis players and nonplayers has been compared. Thirty -two young male experienced tennis players and thirty- two male nonplayers (did not take part in any racket sports game) were evaluated. The accommodative facility was tested with accommodative flippers (+/–2.00 sphere lenses) binocularly. The subject having 6/6 monocular and binocular near acuity with habitual refractive correction was included in the study. Nonplayers of the same age and sex were included in the study. The mean value of the accommodative facility for the players was 11.92 cpm. The mean value of accommodative facility for the nonplayers was 6.66 cpm and the P value was 0.0005 so there were high statistical significant changes between tennis players and nonplayers. This result can be used to detect sports talents and for players with reduced accommodative facility, vision therapy can be used to improve their facility of ocular accommodation
