After using lots of local lenses I moved to crizal lenses and found it above all of them. It is bit costly but the clarity and the smoothness of crizal lenses are incomparable.
It has some features which I personally experienced. Some of them are :
It provides me clearest vision compare to other lenses I used.
It is scratch proof, smudge proof and also water and dust proof.
It also protects your eyes from UV rays.
It is very useful while driving because it reduces the glare and distractory light coming from other vehicles.
It is durable and effortless and easy cleaning.
Overall best for your eyes.
