Asahi Lite HYPER INDEX 1.74 DAS SP double-sided aspherical lens
The ideal double-sided aspherical design
Double-sided aspherical design by adopting a low curve
S degrees direction and direction of C degree astigmatism,
And according to the curvature aberrations in the lens periphery distortion of the image,
As much as possible cut the offensive behavior of glasses at a minimum,
The suppressed. Ever experienced not clear
Make your field of view.
-High refraction rate 1.74
New development of ultra high index 1.74 material adopted.
Negative effects caused by increasing the refractive index by various high-tech
Clear. Never before compared to traditional plastic lenses
Thinner and lighter to success.
Before pursuing not ultra high refractive index of the lens
Material is enough see Abbe number: 33. 0', ':1.47 specific gravity.
Achieve a high balance said.
UV cut < UV 400 >
UV-A harmful UV rays is to cut almost 100%.
It is a very nice lens.
