    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.

    Photochromic Lens2
    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.
    Photochromic Lens4
    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.

    Frequently Asked Questions

    Who are photochromic gray lenses suitable for?
    Photochromic Gray lenses are highly suitable for individuals who frequently travel, work outdoors, or engage in outdoor activities (such as hikers, traffic police, and sanitation workers). They are also recommended for elderly individuals recovering from cataract surgery to minimize light stimulation.
    Are photochromic lenses suitable for driving?
    Regular photochromic lenses may not be ideal for driving because they do not change color inside the car. Full-time drivers are advised to use polarized sunglasses instead for optimal protection and visibility while driving.
    What are the benefits of choosing gray photochromic lenses?
    Gray lenses absorb infrared rays and block 98% of ultraviolet rays. They darken overall light intensity without altering the natural colors of objects, offering a highly realistic and natural viewing experience.
    When should I choose tea-colored (brown) lenses?
    Tea-colored lenses fully absorb UV rays and filter blue light, which enhances visual contrast and clarity. They provide a brightening effect that is exceptionally helpful in poor air quality, foggy environments, or for reducing light stimulation post-surgery.
    What makes the spin coating process better than other methods?
    The spin coating process is an advanced technology where discoloration dye is applied at high speed directly onto the lens surface. This guarantees strong adhesion, high firmness, and a completely uniform and stable color change across the entire lens surface regardless of prescription strength.
