1.56 ASP Introduce

Characteristics

Solved the existing diopter error and distortion aberration completely by the updated aspheric design. 1.56 index aspheric lens to have removed a distortion phenomenon of the lens edge always keep an image clear and distinct.

Solved the perspective problems such as ghost or swim-effect phenomenon.

Compared to non-coated lens, its visibility range became so wider over 15° as to have eye fatigue minimized. Indispensable for driving and company men to need a high-precision lens.
