The Advantages Of Progressive Lenses.
--With progressive lenses, you won't need to have more than one pair of glasses with you. You don't need to swap between your reading and regular glasses.
--Vision with progressives can seem natural. If you switch from viewing something up close to something far away, you won't get a ""jump"" like you would with bifocals or trifocals. So if you're driving, you can look at your dashboard, at the road, or at a sign in the distance with a smooth transition.
---They look like regular glasses. In one study, people who wore traditional bifocals were given progressive lenses to try. The study's author said most made the switch for good.
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.
--SHMC(super hydrophobic coating): To make the lens waterproof, antistatic, anti slip and oil resistance.
