The ideal sunglass near me must have the function of filtering out ultraviolet rays; The color of the left and right lenses is uniform; The scenery should not be distorted or deformed through the lens; Lightweight and comfortable to wear, eyelashes should not touch the lenses and are not easily broken.

PC lenses are tough, not easily broken, and impact-resistant. They are made of specially designated lens materials for sports glasses and are priced higher than acrylic lenses. How to distinguish PC chips? When the lens is removed, small particles can be seen one by one in the cross-section of the lens.

Glass sheets have slightly higher clarity than resin and are less prone to wear and tear; But it is heavy and the material is easy to break, even tempered glass. In addition, its ability to absorb ultraviolet radiation is relatively weak unless it has undergone special processing.

Resin is a chemical substance with a phenolic structure, characterized by lightweight, high-temperature resistance (even lighters cannot burn through), strong impact resistance, and effective blocking of ultraviolet rays. Most sunglasses on the eyeglass mart have resin lenses.

Nylon sheet is a type of synthetic fiber. It has very high elasticity, excellent optical quality, and strong impact resistance, and is usually used as a protective item. Secondly, it has excellent chemical resistance and is suitable for sheet metal frames. It is ultra-lightweight and not easy to crack (without perforated frames). With good optical performance, UV protection, and rich colors, it is currently the best lens on the eyeglass mart.

AC sheet refers to acrylic lenses. It has excellent toughness, is lightweight, has high transparency, and has good anti-fog properties. But this lens type is not scratch-resistant and particularly prone to scratches.
