II. Features:
● ASP lens:
An aspheric lens or asphere is a lens whose surface profiles are not portions of a sph or cyl. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.
The asphere's more complex surface profile can reduce or eliminate sperical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system.

-----Aspherical lenses can reduce aberration and distortion, depending on the material more real
-----Aspherical lenses are thinner, wearing a higher degree of beauty
-----Aspherical lenses are lighter, relieving the visual fatigue caused by oppression effectively |

● 1.56 Index:
1.56 middle index lenses are one of the most popular lenses all over the world. This determines that Aogang 1.56 single vision lenses have the most outstanding optical features:
Lenses with a 1.56 index are considered the most cost effective lens on the market. They possess 100% UV protection and are 22% thinner than CR-39 lenses. They are available with aspheric technology and are not recommended for a rimless drill mount due to its weak nature.
III. Coating Choice:
| Uncoated / Base lens | Hard Coating | AR Coating/Hard Multi Coated | Super Hydrophobic Coating/Crazil Coating |
|
Inner surface of the lens adopt imported element material --- NK55, has excellent performance . |
Enhancing the hardness and resistance on the surface of lenses, prevent lenses from being scraped easily . | Coating anti-reflective film can effectly reduce the reflection of light , make the lenses more cclear and transparent . |
Making the lens waterproof, antistatic, anti slip and oil resistance, also convenient for clean |
