Transition lenses (also called photochromic lenses) darken when exposed to UV light, typically within a minute outdoors, and lighten indoors once UV exposure ends. They provide 100% UVA and UVB protection and filter a significant amount of blue‑violet light, typically 20–26% indoors and over 85% outdoors, depending on the lens type.
Anti-glare coating, also known as anti-reflective (AR) coating, is applied to eyeglass lenses to reduce reflections from both the front and back surfaces of the lenses. This allows more light to pass through the lenses, improving visual clarity and reducing eye strain. Anti-glare lenses are beneficial for night driving, working under brig
Anti-glare coating, also known as anti-reflective (AR) coating, is applied to eyeglass lenses to reduce reflections from both the front and back surfaces of the lenses. This allows more light to pass through the lenses, improving visual clarity and reducing eye strain. Anti-glare lenses are beneficial for night driving, working under bright indoor lighting, and using digital screens for long periods.
Also known as a blue light filter reduces the amount of high-energy visible (HEV) blue light that reaches the eyes. Blue light is part of the visible light spectrum and is emitted by various sources, including digital screens (like computers, smartphones, and tablets), LED lighting, and the sun.
