What should be worn when operating Class 4 lasers to prevent eye injury?

When operating Class 4 lasers, it is crucial to wear protective eyewear specifically designed for laser use due to the high risk of eye injury associated with these powerful lasers. Class 4 lasers are capable of causing permanent damage to the eyes and skin, even from reflected beams. Standard prescription glasses and regular sunglasses do not provide the necessary protection against laser radiation. They may not filter the specific wavelengths emitted by the laser or provide adequate coverage, leaving eyes vulnerable to hazardous exposure. Protective eyewear is specifically engineered to absorb or block harmful laser wavelengths, ensuring that the eyes are safeguarded against potential injuries while working in settings where Class 4 lasers are in use. This specialized eyewear should meet appropriate safety standards and be selected based on the specific laser parameters to offer effective protection.
