There are many tips, here is a quick list:
a. Use the microfiber cloth we sent with your glasses to wipe the lenses and the frame. Don’t use other cloths or materials, as they have rougher fibers that can scratch your lenses.
b. Just use warm water - it’ll break down grease and fingerprints just fine on its own. Never use dish soap, laundry detergent, or other cleaning products. They’ll strip your lens coatings right off the surface!
c. Whenever you’re not wearing your glasses store them in the hard case to keep them safe, especially during the night. Too many pairs of glasses find their sad ending under the night-time crush of a human foot !
