Q. Is laser torch harmful for eyes?

Answer

The retina can be damaged by high-powered lasers because they fire a strong light current into the eye, penetrating the deepest layers of the organ in a matter of milliseconds. The blink reflex that serves to protect the eye from damage is too slow to completely block the laser. Warning labels on these products are obviously insufficient to avoid injuries, according to the researchers, who urge doctors, parents, and teachers to have conversations with children about the risks posed by these products. Depending on the wavelength of the light and the energy absorption qualities of the ocular tissues, laser irradiation of the eye may harm the cornea, lens, or retina.
