General Warnings No complete protection against all rays: Although sunglasses provide UV protection, they are not designed to block all potentially harmful rays (e.g., very strong UV-C). Avoid prolonged direct exposure to the sun, even while wearing sunglasses. Not suitable for direct sun observation: These sunglasses are not intended for direct viewing of the sun, such as during a solar eclipse. Use specialized protective glasses in such cases. Not a safety glass: Sunglasses do not provide protection against mechanical or chemical impacts. For workplace environments, use safety glasses that meet applicable safety standards. Use while driving: Pay attention to the filter category. Lenses in category 4 (very dark tint) are not permitted for use in road traffic. Impairment of vision: Tints may cause color distortion or limitations to vision, especially in low-light conditions. Avoid heavily tinted lenses for activities requiring high precision.
Special Notes for Polarized Sunglasses Reflections and vision changes: Polarized lenses reduce reflections but may also limit visibility of screens or displays (e.g., GPS devices, smartphones). Not compatible with specialized equipment: Polarized sunglasses may interfere with the perception of cockpit instruments or other reflective surfaces. This is particularly important for pilots or technical users.
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: While many sunglasses are made of shatter-resistant materials, extreme impacts or falls may still cause damage. Handle and store glasses carefully. Scratch sensitivity of lenses: Lenses may be prone to scratches. Avoid contact with sharp objects and clean lenses only with a microfiber cloth. Avoid chemicals: Keep sunglasses away from harsh chemicals, including cleaning agents, solvents, perfumes, and sunscreens, as these can damage the coating or frame. Warranty and return conditions: Improper use or incorrect care may void the warranty. Follow the included care instructions and manufacturer guidelines. Do not sit on lenses or apply pressure: Excessive pressure can damage the frame or deform the lenses.
Health Warnings Beware of allergies: Some materials, such as metals or plastics, may cause skin irritation or allergic reactions in sensitive individuals. Use child-appropriate models: Children should wear sunglasses specifically designed for them to optimally protect their sensitive eyes. No protection with damaged lenses: Damaged or scratched lenses no longer provide full UV protection and should be replaced immediately.
Additional Precautionary Notes Use in water: Avoid using sunglasses in seawater without thorough cleaning afterward, as salt can damage the coating. Not suitable for extreme conditions: These sunglasses are not intended for use in extreme environmental conditions (e.g., glacier hiking, high-altitude tours) unless specified for such purposes (filter category 4).
