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.
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. The 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.
Frequently Asked Questions
💡 Who are photochromic gray lenses best suited for?
Photochromic Gray lenses are highly recommended for individuals who travel frequently, work outdoors, or engage in outdoor activities (such as traffic police, sanitation workers, and hikers). They are also ideal for elderly individuals recovering from cataract surgery to reduce light stimulation.
💡 Why might photochromic lenses not be suitable for driving?
Regular photochromic lenses require direct UV exposure to change color. Because car windshields block most UV light, the lenses will not darken effectively inside a vehicle. Full-time drivers are advised to use polarized sunglasses instead.
💡 What is the difference between gray and tea-colored photochromic lenses?
Gray lenses block 98% of UV rays and reduce overall light intensity without altering the natural colors of objects. Tea-colored lenses block UV rays and filter blue light, which enhances contrast and clarity, making them excellent for driving or foggy conditions.
💡 What advantages does the spin coating process offer?
The spin coating process applies the discoloration dye uniformly onto the outer surface of the lens at high speed. This advanced technology ensures strong adhesion, high durability, and a completely even color transition across all areas of the lens, regardless of prescription strength.
💡 Do these lenses block UV rays?
Yes, the UV420 Photochromic Gray Lens provides 100% blockage of harmful UV rays, protecting your eyes from strong sunlight damage and restoring visual accuracy.
