WHY CR39 ORGANIC GLASS?
CR39 is 20 times more shatter-resistant than mineral glass. If broken, the glass fragments are blunt, preventing any injury.
CR39 is the best-known organic material. Because it conducts heat very well, it evaporates much less than mineral glass. It is particularly notable for its light weight.
WHY ANTI-REFLECTIVE LENS?
Anti-reflective lenses are a type of lens that prevents glare. Anti-reflective lenses effectively block light reflections, preventing negative light interference. Because anti-reflective lenses contain water and oil, their composition results in very low reflection density. This feature of anti-reflective lenses prevents the negative effects of sunlight. Furthermore, anti-reflective lenses with a light tint provide added comfort when driving at night by blocking oncoming vehicle headlights.
