No matter what coating they have, they will scratch easily. I've found that
most scratches are due to operator behavior. My bifocals have a 2nd bifocal
at the top, great for working under an auto lift.

To avoid most scratches I suggest:
+ clean by washing then air dry
+ don't lay them lens side down
+ don't let the temples touch the lenses

Many recommend a soft carrying bag that can double as a wiping cloth. Be
aware that the temples may/will touch while in the bag. I clip the temples
together with a small binder clip before inserting into the bag. I get a
good life out of mine by following these tips.
