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. Wipe and dry using a Protech cleaning cloth or equivalent soft, lint free cloth.
