The present invention relates to an apparatus and a method to measure a UV transmission ratio of an eyeglasses lens having different refractive power capable of simply and accurately measuring the UV transmission ratio without correcting the UV transmission ratio, even measuring the eyeglasses lens having different refractive power. The apparatus to measure the UV transmission ratio comprises: a UV light source to emit a UV light to a measuring target; a UV diffuser to equal the UV light emitted by the UV light source; a pin-hole to pass the UV light equalized by the UV diffuser to a minute penetration hole; a light path setting unit to set a light path of the UV light source passing through the pin-hole; and a UV detector to detect the UV light passing through a measuring target located on the light path. |
