Wear sunglasses that screen ultraviolet light when you are exposed to sunlight or are in the vicinity of arc welding. Wear this type of sunglasses even during the winter. Be careful when using household cleaners. Many household products contain strong chemicals. Drain and oven cleaners are very dangerous. They can lead to blindness if not used properly.
