Wipe your eyeglasses clean with liquid soap if you prefer not to use an anti-fog wipe or spray on your eyeglasses. Squirt a drop of liquid soap on a damp rag and rub it onto your eyeglass lenses. Allow the soap to soak onto the lenses for a few minutes. Take another damp rag and gently wipe your eyeglass lenses clean. Invest in eyeglasses that feature an anti-fog coating on the lenses.
