Optical glasses are visual aids that improve vision by altering the path of light. They help people with poor vision see objects more clearly by adjusting the direction and focus of light.
Fitting Principle: Optical glasses correct visual defects by adjusting the curvature of the lenses. For farsighted individuals, the lenses focus light more precisely, helping the eye focus on the retina; while eyeglass lenses help nearsighted individuals by dispersing light more.
Aesthetics: Optical glasses often feature stylish designs, making them more attractive and encouraging wearers to wear them. Modern optical glasses also utilize lightweight materials and thin designs, resulting in greater comfort when worn.
Material Selection: Optical glasses lenses can be made from various materials. The most common are plastic and glass. Plastic lenses are lightweight and less prone to breakage, while glass lenses offer higher optical quality.
UV Protection: Many optical glasses also feature UV protection. Prolonged exposure to ultraviolet (UV) radiation can damage the eyes; therefore, UV protection in optical glasses effectively protects the eyes from harmful UV rays.
