It's easy to take great care of your eyeglasses and important in extending its life-span, so here's the best way to do it:
To keep your lenses clean from day-to-day, simply use the included cleaning cloth to wipe away any visible smudges. Sometimes you'll want to give the eyewear a deep clean. To do so, all you will need is a soft cloth, simple dish soap, and water. Mix the dish soap and water together, take your cloth, give it a good soak, and give your frame and lenses a thorough cleaning.
Remember to refrain from using hot water because exposure to high heat can cause damage to the lenses. Otherwise, using these methods to keep your glasses nice and clean will ensure that you can use them for a long time.
