Purpose: The purpose of this study was to investigate the effect of lens color of sunglasses on stereoacuity by experiment.
Methods: We conducted a stereotaxic test using a RANDOM DOT with a polarizing lens at an examination distance of 40 cm in 100 men and women aged 20 to 60 years without any specific ocular disease. Then, seven kinds of PVC color film such as yellow, black, brown, red, purple, blue and green were put on the polarizing lens and the stereoscopic examination was carried out again.
Results: When the lens color of the sunglasses is yellow, black, and brown, it affects less stereoscopic effect. However, red, purple, blue, and green have much influence on stereoscopic effect. Especially, the red and purple colors affected the stereoscopic vision. In blue and green, the effect of stereoscopic vision was different according to the people.
Conclusions: Depending on the lens color of the sunglasses, stereoscopic vision is affected, which can cause problems in binocular vision. Therefore, when choosing sunglass lens color, many buyers need to pay attention.
