Application Scenarios for Photochromic Lenses
Photochromic Gray lenses are suitable for people who frequently travel, engage in outdoor activities, or work, such as hiking enthusiasts, sanitation workers, traffic police, etc. They can also be used for elderly people after cataract surgery, and it is recommended to wear brown lenses to reduce light stimulation.
However, teenagers and full-time drivers may not be suitable for wearing color changing lenses, as regular color changing lenses do not change color inside the car and are more suitable for using polarized sunglasses while driving.
Color is an Important Consideration Factor
When choosing photochromic lenses, color is an important consideration factor. The common colors of color changing lenses are gray, brown, and green, with gray and brown being the most commonly used.
Gray lenses:
Can effectively absorb infrared rays and block 98% of ultraviolet rays. Observing objects through gray lenses, the natural color of the object will not change, but the overall tone will darken and the light intensity will be significantly reduced, providing a more realistic and natural visual experience.
Tea colored lenses:
Can fully absorb ultraviolet rays and effectively filter blue light, thereby improving visual contrast and clarity, bringing a brightening effect. It is particularly suitable for wearing in poor air quality or foggy environments, and can be considered the preferred choice for drivers.
Advantages of Photochromic Lenses
UV420 Photochromic Gray Lens:
- 100% blockage of harmful UV rays.
- Diminishing damage from strong sun ray and restoring image accuracy.
- Light intelligent lenses automatically adapt to changing light conditions.
- Anti-Reflection Coating and spin coating process.
How is spin coating technology implemented:
The discoloration factor is uniformly applied to the substrate surface at high speed. No matter how high the degree, each area is guaranteed to change color completely evenly.
Advantages of spin coating process:
Spinning coating process is the most advanced technology at present. Discoloration dye is applied to the surface of the lens (above the substrate) by spin coating technique, to form a discoloration layer. The color change layer has strong adhesion, high firmness, and more uniform and stable color change.
