How to use

Wear the sunglasses so the frame rests comfortably on the nose and temples, ensuring the wraparound shape shields eyes from direct and peripheral glare. Allow the photochromic lens time to adapt when moving between shaded and bright environments—adaptation time varies with temperature and light intensity. For lens changes follow the manufacturer’s instructions to swap lenses securely and avoid touching the inner surfaces to maintain optical clarity.

Recommendations

Use these sunglasses for activities where rapid changes in brightness occur. Clean lenses with a soft microfiber cloth and mild lens cleaner. Store in a protective case when not in use to preserve frame finish and lens performance.
