Abstract	Contrast sensitivity function was believed can be enhanced by wearing amber tinted lenses. However the increment varied with respect to significant diagnosis. The aim of this study was to assess contrast sensitivity with and without wearing amber lens between youth hockey player and non-hockey player. Preliminary examination was done to assess on refractive status and ocular health among eighty healthy male subject aged between 13 to 16 years old where they were divided into youth hockey player (n=40) and non-hockey player (n=40). Pelli-Robson contrast chart was used in measurement of contrast sensitivity with latest refractive correction, two times; with and without wearing amber tinted lens. Contrast sensitivity between youth hockey player and non-hockey player seems to show a significant difference in both conditions of without and with wearing amber tinted lens with statistical value U = 312.0, z = −4.95, p<0.001 and U = 434.5, z = −3.89, p<0.001 respectively. This scenario also shows an increment in contrast sensitivity value when the comparison made between without and with wearing amber tinted lens in both groups. The increment among youth hockey player was clinically significant (T = 68, z = −2.392, p <0.05) and among non-hockey player (T = 253, z = −4.284, p <0.001). However, based on recommendation from previous report, the value obtained is not considered clinically significant until the changes of contrast sensitivity using Pelli-Robson contrast chart achieve ±0.14 log unit. Previous study that claimed amber tinted lens can enhance contrast sensitivity was proven statistically significant in this research but in clinical aspect, the increment was not sufficient enough to be established as an enhancement of contrast level.
