Soap Application When Eyeglasses Steam
To prevent annoyance caused by a deposit of moisture upon eyeglasses, when going from a cold into a warm atmosphere, moisten the tips of the fingers and rub them over a cake of soap. Then rub them over the lens, and polish as usual. One application every day or two is all that is necessary.

Money Cleans Eye Glasses
To clean your eye glasses use a soft bank note. It will not scratch or mar them and leaves them beautifully clear. First steam the lenses with your breath, then wipe and polish them with a piece of currency. A trial will prove this far better than using a handkerchief.
