• The Meaning Of The Photochromic Lens

Photochromic lenses are optical lenses that darken on exposure to specific types of light of sufficient intensity, most commonly ultraviolet (UV) radiation. In the absence of activating light the lenses return to their clear state. Photochromic lenses may be made of glass, polycarbonate, or another plastic. They are principally used in eyeglasses that are dark in bright sunlight, but clear in low ambient light conditions. They darken significantly within about a minute of exposure to bright light, and take somewhat longer to clear. A range of clear and dark transmittances are available.

• Outstanding Color Performance

1. Fast speed of changing, from white to dark and vice versa.
2. Perfectly clear indoors and at night, adapting spontaneously to varying light conditions.
3. Very deep color after change, the deepest color can be up to 75~85%.
4. Excellent color consistency before and after change.

• The Function Of The Photochromic Lens.

---Photochromic lenses change color in sunlight. Specifically, they darken when exposed to UV rays.

---Most photochromic lenses are clear indoors and at night, and turn gray or brown when in direct sunlight.

---Aoang photochromic lenses are a type of . They start at clear color and turn dark rust in sunlight. They are a daytime-only lens that increases contrast and visual acuity. They’re great for driving, golfing, and active sports.

As the pioneer of Photochromic technology leads the industry in creating lenses that adapt to any light condition in any setting. Darkening in bright sunlight and lightening in overcast conditions, Photochromic technology allows your eyes to adapt to any light, in any weather. The result is a view of the world so crystal clear, you’ll notice natural beauty you’ve never seen before.

III. Coating Choices:

Hard Coating: It also can be also anti-scratch coating, its purpose to help the lenses be destoried. HMC EMI Coating : It also can be called anti-reflection(AR) coating or hard multi coating, the technology is coating another anti-reflective coating on the hard coating. Its purpose to perfectly reduce harmful ray and enhance the vision effect. Super hydrophobic coating: It also can be called crazil coating, it takes the lenses waterproof, antistatic, anti slip and oil resistance which can keep half one year ~one year.
