I bought my prescription eyeglasses last week, and it costed me 100 dollars for PC lenses, I am really careful about it, anyone can tell me which is the best way to clean PC lenses? Appreciate!

You can daub some depurative on the lens, and wipe dirty pot buy a soft cloth, if there's too much grease and the above method can not work effectively, you can choose a ultrasonic washing machine, you can find it almost in every glasses shop!
