Maintaining Your Eyewear
Storage: Leaded Eyewear should be stored in a protective case in normal room temperature and low humidity conditions when not in use.

Maintenance: Examine Leaded Eyewear frequently and before each use. Cease use and replace or repair immediately if the eyewear are chipped, pitted, or damaged. You may tighten screws/hinges if they loosen. Cleaning the Frame: Use any standard eyewear cleaning cloth. Diluted soap and water usually will not discolor or damage the frame. Cleaning the Lenses: Never use ammonia or chlorine-based cleaners. Use of alcohol is permitted for lenses that do not posses an anti-reflective (A/R) coat. To clean A/R coat lenses soak in diluted soap and water. DO NOT allow water to remain or dry onto the lenses as this can discolor/damage the lens.
