Lens care is essential for maintaining the clarity and longevity of your eyeglasses or contact lenses. Regular cleaning helps remove dirt, oils, and bacteria that can accumulate on the lenses. For eyeglasses, use a microfiber cloth and a gentle lens cleaner. For contact lenses, always wash your hands before handling them and use the recommended cleaning solution to disinfect and store them properly. Proper lens care also involves following the manufacturer's guidelines. Replace contact lenses as directed, and avoid wearing them longer than recommended to prevent eye infections. Additionally, store eyeglasses in a protective case when not in use to avoid scratches and damage.
