Use a microfiber cloth and lens spray cleaner provided to you by PVFV.
Spray them to remove all debris and then gently wipe both sides of the lenses, and all parts of the frame.
You may also rinse them with water and wash them with mild non-lotion dish soap, rubbing both sides of the lenses with your fingers, followed by a thorough rinse. Dry them with a lint free cloth.
Always take your frame on and off with two hands to preserve the adjustment.
Don’ts
Use your shirt or blouse to clean your glasses, especially when the lenses are dry. This can scratch your lenses.
Use household glass or surface cleaners to clean your eyeglasses. These products have ingredients that can damage eyeglass lens and coatings.
Leave your glasses inside the car/heat/direct sunlight. This may damage your frame and lenses.
Put your frame over your head. This will stretch your frame out of adjustment.
Remember: If they’re not on your face, they’re in a case!
