Ensure the frame fits closely enough to block light from the sides for optimal eye protection; adjust temple placement if necessary.

Usage recommendations

Ensure proper fit before use to achieve full eye protection. Clean lenses with a soft cloth and store the glasses in a protective case when not in use.
