Sunglass Lens Coatings, Sunglass Lens Materials

The extra highly-priced the shades, the much more likely they’re to have several layers of coatings. these can include a hydrophobic coating to repel water, an anti-scratch coating to improve durability and an anti-fog coating for humid situations or excessive-energy sports.

mirrored or flash coating refers to a reflective movie applied to the outside surfaces of some sunglass lenses. They reduce glare through reflecting tons of the light that hits the lens surface. mirrored coatings make gadgets seem darker than they are, so lighter tints are regularly used to catch up on this.

The material used in your sunglass lenses will have an effect on their clarity, weight, sturdiness and value.

Glass gives superior optical clarity and advanced scratch-resistance. however, it’s heavier than other substances and costly. Glass will “spider” whilst impacted (but not chip or shatter).

Polyurethane presents advanced effect-resistance and terrific optical clarity. It’s bendy and light-weight, but high-priced.

Polycarbonate has first rate impact-resistance and superb optical readability. It’s less expensive, lightweight and coffee-bulk, however less scratch-resistant.

Acrylic is an less expensive opportunity to polycarbonate, first-rate acceptable for informal or occasional-use shades. It’s much less long lasting and optically clear than polycarbonate or glass with some image distortion.
