Purpose: The change of straylight with clear versus cosmetic soft contact lens according to time and the effect on visual acuity were analyzed.
Methods: Healthy twenty five young subjects( age 19-23 years ) were fitted with clear and cosmetic SCL( etafilcon A ). After wearing contact lenses after ten minutes and eight hours, using straylight measure instrument, the values were measured. Subjects were repeated three times and were analyzed the mean log MAR.
Results: The straylight values were statistically different between clear and cosmetic contact lens after wearing ten minutes ( p=0.03, p<0.05 ) and eight hours ( p=0.00, p<0.05 ). Subjects on clear SCL were no difference on the changes of straylight in relation to time. The straylight values of cosmetic SCL were statistically no difference according to time.
Conclusions: The straylight values of SCL were increased owing to color and were influenced for the color. The measure of straylight as well as contrast sensitivity visual acuity was suggested for examining the quality of visual acuity.
