Clean your glasses with the appropriate accessory: wipe, microfiber or spray for optics (ORAO accessories range). Conversely, avoid paper towels, silicone-containing cloths, paper tissues that may scratch your glasses. As well as cleaning products, disinfectants, acetone, which could damage your glasses and their treatments. If there are projections on your glasses, do not dry them dry: pass them under clear water first.
The quality of your vision depends on the proper care of your sunglasses. The case is not superfluous! Rows inside your glasses will be protected from scratches, shocks and crushes.
All sunglasses are tested under the actual conditions of use for which they were designed. Design teams, product managers, engineers, model makers ensure that the program for which the product has been designed and developed perfectly matches its use in the field.
