Super Thin Aspheric(1.67)
Super Thin Aspheric (1.67) lenses are light, thin and scratch-resistant with 100% UV protection. Also, they are more impact-resistant than CR-39 resin lenses. They provide optical performance similar to glass lenses, as MR-7 lenses have a high index and Abbe number. The lenses are suitable for strong prescription, with spherical power from +/-6.00~+/-9.00 and cylindrical power from +/-3.00 to +/- 4.00.
