Material and Environmental Notes Sensitivity to high temperatures: Frames and lenses may deform or become damaged with prolonged exposure to high temperatures (e. g., in a car under direct sunlight). Break resistance: Although many frames are made of shatter resistant materials, extreme impacts or falls may still cause damage. Handle and store frames carefully. Avoid chemicals: Keep the frames away from aggressive chemicals, including cleaning agents, solvents, perfumes, and sunscreens, as these can damage the coating or frame.
