It ensures better accuracy

The correct answer is: Lasers can cause eye and skin damage

Wearing goggles when using laser light is crucial primarily because lasers can cause significant eye and skin damage. Lasers emit concentrated beams of light that can easily be focused onto the retina, leading to permanent injury or blindness. The intensity of laser light is much higher than that of regular light sources, which is why protective eyewear is essential to absorb or block harmful wavelengths. Goggles specifically designed for laser use provide a barrier that protects sensitive eye tissues from high-intensity light exposure. The importance of wearing appropriate goggles cannot be overstated, especially in environments where lasers are utilized for various applications like medical, industrial, or research purposes. Goggles are designed to filter out particular wavelengths of laser light, reducing the risk of injury while allowing the user to carry out their work safely. This protective measure is a fundamental aspect of laser safety protocols.
