Which Element’s Oxide Is Used to Prepare Coloured Lenses in Sunglasses?

Sunglasses Composition and Elements

Sunglasses come in various lens colors. Each color blocks different light wavelengths. Gray, brown, and green lenses block brightness and glare. They cause little color distortion. Photochromic lenses contain silver salts. They darken in sunlight and lighten indoors. Polarized lenses block horizontal light waves. This reduces glare from water, snow, cars, and more. Gradient lenses transition from dark to light. The top blocks overhead rays. The bottom shows colors clearly. Plastic and glass lenses have pros and cons. Plastic resists breaks but scratches easily. Glass offers clarity but more weight. The choice impacts cost, comfort and durability.
