We recommend cleaning your glasses with a store-purchased lens cleaner. Never submerge your glasses in water, hot or otherwise. Doing so can damage your glasses and void your warranty. Pharmacies and department stores are common stockists of lens cleaners. Make sure that you buy a product that suits your lenses. If you have glasses with an anti-reflective (AR) coating, you will need a product approved for them. Use a liberal amount of spray to remove dust and debris. Wipe the lenses dry with a microfibre cleaning cloth. These cloths excel at drying lenses. They absorb oil and reduce smears and streaks. Be aware that they can be so good at collecting debris that it remains on the cloth. Ensure that you clean your microfibre cloth after each use. Hand wash it with dishwashing liquid and allow it to air dry. Another handy option is individual pre-moistened lens wipes. These come in disposable packages and are also available at most pharmacies. Before you use one of these lens wipes, be sure to clear your lens of any debris. Otherwise, you run the risk of wiping said debris into the lens and causing a scratch. Our recommended lens cleaner spray is also available in our online store.
