re: costa del mar sunglasses, how do u clean the lenses?

Only use purified water, preferably tears from a virgin.
For wiping, use 1000 count, hand spun Egyptian cotton, light colors only.
For drying, use a ultrasonic blower, between 1300-1350 CFMs, no more, no less.

Then, encapsulate the glasses in a clean Ziplock inside the provided hard case.


Don't let this happen again.
