Why are lasers classified by the FDA?

Lasers are classified by the FDA primarily to assess their potential hazards to users and patients. This classification system allows the FDA to implement safety standards that ensure lasers are used safely in various applications, particularly in medical and cosmetic procedures. By evaluating the potential risks associated with different types of lasers, the FDA can recommend appropriate safety measures, usage guidelines, and training requirements to protect both practitioners and patients from harm. This approach is crucial in minimizing the risk of injury, ensuring effective and safe use of laser technology in healthcare settings.

The other options, while they may seem relevant in different contexts, do not directly pertain to the primary reason for the FDA's classification of lasers. The focus is specifically on safety and risk assessment rather than manufacturing processes, sale price regulation, or design protocols.
