안경렌즈와 굴절측정렌즈의 굴절력 관계에 대한 연구

A Study of the Power of Glasses Lens and that of Trial Lens

Today's diopter of optical lens can reveal the derivation apparently compared with that of refraction measure lens. First, this is applicable when there is a difference in the shape and thickness basically and when the lens is used for a short distance. When measure and use it, an astigmatic difference is occurred by the discordant light passage. This is also applicable to optical lens with prism diopter lens and in some cases, must be corrected relating to the diopter incidently.
