Features
The most common materials available for use in lenses used to be glass and a hard resin called CR-39. With the continuous improvement of technology, there are more requirements of CR39(optical/plastic) lenses than glass lenses. We are a manufacturer of optical lens, and in these lenses, 1.56 index lenses are one of the most popular lenses all over the world. Furthermore, lenses with 1.56 index are considered the most cost effective lens on the world market.
Thickness: Under the same prescriptions, 1.56 index lenses are thinner than 1.499 lenses. as the increase in diopters, the difference will be bigger. In the other word, high index materials are classified by numbers. Again, the higher index, the thinner and lighter the lens.
Weight: Due to the thickness, it’s obvious that 1.56 lenses are lighter than 1.499 lenses in the same diopters.
AR Coating
–HC(hard coating): To protect the uncoated lenses from scratch resistance.
–HMC(hard multi coated/AR coating): To protect the lens effectively from reflection, enhance functional and charity of your vision.
