By Specific Functions
All specific function lenses adjust their tint based on UV light, primarily changing to brown and gray, with a refractive index of 1.56. They come in single vision (S.V.), round-top, blended, flat-top, and progressive designs for various visual needs.
Clear Photochromic Lens
- Maintains a clear appearance indoors for a natural look and changes tint at a standard rate under UV light for balanced transitions.
Fast Change Photochromic Lens
- Transitions between clear and dark in 5 seconds, ensuring immediate comfort and protection, and is designed for fast adaptation to changing light conditions, reducing adjustment time.
Photochromic Blue Cut Lens
- Filters harmful blue light from screens and lighting, protecting against eye strain, and combines photochromic and blue light blocking for comprehensive UV protection.
Application
Our photochromic lenses provide versatile benefits for a wide range of applications, including driving, sports, professional safety, and everyday use.
Driving & Motorcycling
- This category features eyeglass lenses designed for road use. Photochromic lenses for driving automatically adjust to varying light conditions, improving visibility and minimizing glare.
- Motorcycle transition lenses for men and women automatically adjust their tint to sunlight, providing UV and wind protection and ensuring clear, optimal vision for all riders.
Outdoor Sports & Activities
- Designed for outdoor sports enthusiasts, these lenses provide both versatility and protection.
- Transition lenses for mountain biking and photochromic lenses for running are engineered to adapt swiftly to changing sunlight conditions, ensuring clear vision throughout your activities.
Work & Safety
- Essential for professionals requiring protective vision gear, photochromic lenses in safety eyewear offers dual benefits: eye safety and light adaptation.
- These lenses adjust to lighting changes, providing impact resistance and UV protection for safety and comfort in any setting.
Everyday & Multifunctional Use
- These photochromic lenses support daily and special activities, including computer use where they reduce blue light exposure and adjust to ambient light to minimize eye strain.
- Similarly, photochromic reading lenses adapt to both indoor and outdoor lighting, ensuring comfort and clarity for reading under any conditions.
Enhanced Optical Clarity
Spin coating ensures uniform material distribution on the lens, maintaining clarity and preventing distortions, ideal for single-vision lenses.
Improved Photochromic Response
Spin coating ensures an even photochromic layer for uniform tinting under UV light, providing consistent shading and reliable UV protection.
Lens Index Customization
Indices available: 1.50, 1.56, 1.61, 1.67, and 1.74; higher indexes provide lighter, thinner lenses. Indices 1.56 to 1.74 are ideal for blue-cut lenses.
Durability
Spin coating strengthens lens coatings, boosting adherence and scratch resistance, and reducing delamination over time.

POPULAR QUESTIONS
These lenses contain special photochromic molecules embedded within the lens material (resin, PC, or acrylic). When exposed to UV light, these molecules alter their structure, making the lens darken. This process is reversible—when the UV light is gone, the molecules revert to their original form, and the lenses become clear again.
Photochromic gray lenses are generally better for driving because they provide true color recognition and reduce light intensity without altering the color spectrum. Brown lenses, however, are better suited for enhancing contrast in low-light conditions, which can also be beneficial in certain driving situations.
The main advantages are their aesthetic and comfort benefits due to being thinner and lighter. This makes high-index photochromic lenses more comfortable for everyday wear, particularly for those with stronger prescriptions who might otherwise have thick and heavy glasses.
Yes, these lenses are designed to provide optimal visual comfort in both indoor and outdoor settings. Indoors, they help minimize exposure to blue light, reducing potential eye strain and sleep disturbances. Outdoors, they adjust to the light conditions by darkening, which enhances visual clarity and protects from UV rays.
They are ideal for individuals who experience frequent changes in light environments, such as outdoor enthusiasts, commuters, and those who drive at night. People sensitive to bright lights or who spend long hours in front of computer screens can also benefit from the reduced glare and eye strain.
The level of UV protection provided by photochromic lenses is not directly related to their darkness. All photochromic lenses are designed to offer 100% UV protection, regardless of how dark they get. The darkness level primarily affects glare reduction and comfort in bright conditions.
