Sunglass Lens Options
Anti-reflective: Anti-reflective lenses block reflected light, and most have a special layer that prevents spots and makes them easier to clean.
Polarized: Polarized lenses absorb light from horizontal surfaces, like roads and water, to reduce glare.
Photochromic: These lenses do double duty as they are alternate from clear indoors to a sunglass lens outdoors.
Glass: Glass lenses are very scratch-resistant and provide crisp, clear vision. However, glass lenses are not designed for high-impact activities.
Polycarbonate: Polycarbonate lenses are impact-resistant, making them a smart choice for children and active adults.
Plastic: Basic lens material originally developed for aircraft windows.
Nylon: A flexible plastic that withstands extreme temperatures. Various types of nylon include TR90, Grilamid or TR55, among others.
