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.

--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.
