Lenses made from 1.61 high-index material are thinner and lighter than standard plastic lenses (like 1.5). The higher refractive index means that they can bend light more effectively, allowing the lenses to be thinner even for those with higher prescriptions.

Light-Adaptive: These lenses are equipped with photochromic technology, meaning they automatically darken when exposed to UV light (such as sunlight) and lighten when indoors or in low-light conditions. This feature eliminates the need for a separate pair of sunglasses, making them extremely convenient for people who frequently transition between indoor and outdoor environments.

UV Protection: When the lenses darken, they provide 100% UV protection, helping to shield the eyes from the harmful effects of ultraviolet rays that can contribute to conditions like cataracts and macular degeneration.

Reduced Glare: The ability to adjust to light conditions helps reduce glare in bright outdoor environments, making them more comfortable to wear in sunny conditions.
