Every lens we sell includes a scratch-resistant coating and an ultraviolet protective filter. Other options include an anti-reflective coating, or mirror coat, for sunglasses.
Anti-reflective coating allows more light to pass through the lenses. This reduces eyestrain from computer glare, improves vision at night and eliminates light halos around car headlights and streetlights, and it makes the lenses “disappear” on your face. The anti-reflective coating has a one-year warranty against scratches.
A mirror coat is used to reduce glare and brightness on sunglasses. A tint can be added to any lens for a variety of purposes.
