Tips for cleanning eyeglasses lenses effectively

[prescription glasses]

Here's my little ways of cleaning eyeglasses lenses, sometimes, it’s difficult to clean then dots up if they attach on lenses firmly: first one is using some detergent, you may all know about it. just daub little on your lenses, then cleanse it with a piece of soft cloth; and the second, if there are dots on the lens that you can't remove it by that way, you can try ultrasonic washing machines. You can find them in many local eyeglasses stores.
