2. Visual Effect: Compared with high index lenses, 1.56 lenses have higher ABBE value, can provide the more comfortable visual experience.
3. Coating: The uncoated lenses are easily subjicted and exposed to scratches, hard coating lenses can effectly scratch resistance.
Tinted:
Unlike Photochromic Lenses, solid tint lens coatings remain tinted at all times. Tints of virtually any color or darkness can be applied to eyeglass lenses. Lighter fashionable tints are often used primarily for cosmetic purposes while dark tinting can turn any pair of glasses into sunglasses. Additionally the color can be added as a solid tint where the darkness and color are consistent throughout, or as a gradient tint where the color darkness is greatest at the top of the lens and then gradually fades toward the bottom. There are plenty of options here for customization.
