What are the major organs susceptible to laser damage?

• A. Eyes and skin
• B. Heart and lungs
• C. Lungs and skin
• D. Brain and eyes

Answer: (A)

The main idea is that laser energy can directly injure tissues that are exposed to it, especially when the energy is focused or absorbed intensely. The eyes are highly vulnerable because the eye naturally focuses incoming light onto the retina, concentrating energy in a tiny, delicate area where even brief exposure can cause permanent vision damage. The cornea and lens can also suffer harm from certain wavelengths, leading to surface burns or cataracts. The skin is the other primary target since it is often in the beam’s path; high-intensity exposure can cause burns, redness, and deeper tissue injury, with the level of risk depending on the wavelength and exposure duration. In typical laser work, these two—eyes and skin—are the organs most at risk, whereas the heart, lungs, or brain are not directly impacted by standard laser exposure unless other, unusual hazards come into play.
