Manufacturing Technique

1.INTELLIGENT COLOR CHANGE
The darkness of the after-changing color of photochromic lenses are decided by the intensity of ultraviolet light.
The photochromic lens can adapt to changing light, so your eyes don't have to do this. Wearing this kind of lens will help your eyes relax a bit.

2. HOW DO PHOTOCHROMIC LENSES WORK?

There are billions of invisible molecules inside the photochromic lenses. When the lenses are not exposed to ultraviolet light, these molecules maintain their normal structure and the lenses remain transparent. When they are exposed to ultraviolet light, the molecular structure begins to change shape. This reaction causes the lenses to become a uniformly colored state. Once the lenses are out of sunlight, the molecules return to their usual form, and the lenses become transparent again.

3. WHY SHOULD WE WEAR PHOTOCHROMIC LENSES?

☆ They are highly adjustable to varying lighting conditions in indoor and outdoor environments
☆ They provide greater comfort, since they reduce eyestrain and glare in the sun.
☆ They are available for most prescriptions.
☆ Protect eyes from harmful UVA and UVB rays of the sun (reducing risk of cataracts and age-related macular degeneration).
☆ They allow you to stop juggling between your pair of clear glasses and your sunglasses.
☆ They are available in different colors to suit all needs.
