Anti-reflective coatings are used to help provide protection against glare, scratches, smudges, dust, water, and UV rays. We exclusively use Crizal coatings (www.crizalusa.com) for that purpose. If you care about the appearance of your glasses, use a lot of digital devices, drive at night, or participate in outdoor activities (and who doesn’t fall into at least one of those categories?), then a Crizal coating will be very helpful for your glasses!
