Abstract

Recently, a study to evaluate the optical properties of wearing contact lens has begun to improve the quality of vision (QOV). Because soft contact lens (SCL) is composed of a soft material, it deforms along the cornea when it is worn on the eye. Therefore, it is necessary for the study of QOV to develop a method to measure SCL shape of the soft material. In this study, the shape of SCL in a saline was measured by laser slit light. As a result, the measurements became almost same as value of standard of SCL. Front curve and shape of the bevel region which are non-publication were also measured.
