What are the materials of eyeglass lenses?
Author:
Resin lenses: Lightweight, shatter-resistant, and impact-resistant, they are currently the most commonly used lens material. Suitable for daily wear, especially for children and sports enthusiasts.
Glass lenses: Good optical performance and strong wear resistance, but heavier and fragile, now less commonly used.
PC lenses (polycarbonate): Very lightweight and extremely impact-resistant, often used for children's lenses and sports glasses, but with slightly poorer wear resistance.
High refractive index resin lenses: Thinner than ordinary resin lenses, suitable for patients with high myopia or hyperopia, and more aesthetically pleasing.
Progressive multifocal lenses: Suitable for patients who need to correct myopia, hyperopia, and presbyopia simultaneously. The upper part of the lens is for distance vision, the lower part for near vision, and the middle is a transition zone.
Blue light blocking lenses: Based on resin or high refractive index lenses with an added blue light blocking coating, they reduce the eye irritation caused by blue light emitted from electronic screens, suitable for people who use computers or phones for long periods.
Photochromic lenses: Added photosensitive materials to ordinary or progressive lenses that darken when exposed to ultraviolet light, suitable for environments with significant indoor and outdoor light changes.
Polarized lenses: Effectively reduce strong light reflections, commonly used in sunglasses, suitable for outdoor activities.
