This refers to a plain lens with no coatings.
This lens is treated with a chemical dye that blocks out ultraviolet (UV rays of up to 400 nm wavelength, thus providing UV protection.
This protective coating makes the lens surface scratch-resistant by increasing the abrasion resistance of the lens material. It is best to have all plastic lenses hard-coated.
This Combines 2 Types Of Coating: 1. Hard Coat that is sturdy and scratch-resistant 2. Anti-reflection Coat (AR) that reduces surface reflection
