CR39 Lenses: The Smart Choice for Daily UV Defense
As the days grow longer and the sun shines brighter, it’s easy to enjoy the season—but don’t forget to protect your most sensitive asset: your eyes.
Many people remember to apply sunscreen, but UV protection for your eyes is just as critical. Prolonged exposure to ultraviolet rays and reflected glare can lead to immediate discomfort like eye strain, watering, and blurry vision, and even long-term issues such as cataracts, macular degeneration, and skin damage around the eyes.
Why BV Sunglasses Choose CR39 — And Why You Should Too
At BV Sunglasses, over 80% of our lenses are made from CR-39, a high-performance lens material trusted by optical professionals worldwide.
But what exactly is CR-39?
CR-39 (chemical name: allyl diglycol carbonate, not to be confused with polycarbonate) is a specialized plastic lens material originally developed for military use. It is lightweight, impact-resistant, and known for its high Abbe value, which means less chromatic aberration and clearer, sharper vision than standard plastic lenses.
CR-39 lenses are also cost-effective, making them a popular choice in both prescription and non-prescription eyewear. They can be used in single vision, progressive lenses, and can be treated with scratch-resistant, anti-reflective, or UV-protection coatings for enhanced performance.
The Advantages of CR-39 Lense
Optical Clarity That Rivals Glass
CR-39 offers superior visual sharpness compared to standard plastic lenses, without the weight and fragility of glass.
100% UV Protection
All our CR-39 lenses block 100% of UVA and UVB rays, helping prevent sun-related eye conditions while keeping your vision clear and comfortable.
Lightweight Comfort, All Day Long
Despite their excellent clarity, CR-39 lenses remain ultra-lightweight, reducing nose and ear pressure for long-term wear.
Scratch Resistance
With a hard surface coating, CR-39 lenses are more scratch-resistant than most basic plastic lenses, making them ideal for daily use.
Reduced Glare & Eye Fatigue
Thanks to their low internal reflection, CR-39 lenses are gentler on your eyes—especially in high-glare environments like beaches, roads, or open water.
More Than Just Lenses—A Commitment to Quality
Our CR-39 lenses are paired with carefully handcrafted acetate frames, offering a premium look and feel. Acetate is not only biodegradable and hypoallergenic, but also allows us to create a wide range of stunning colors and finishes to match your personal style.
