To use these safety glasses, simply put them on your face, making sure the nose bridge sits comfortably on your nose and the arms curve over your ears. These glasses are suitable for various activities where eye protection is needed. When wearing, ensure the lens is clean for clear vision. After use, gently wipe the lens with a soft cloth to keep it clean. Avoid scratching the lens with sharp objects. Store the glasses in a dry place and keep them in their individual packaging to prevent damage. If the glasses are damaged, stop using them immediately and replace with a new pair.
