Technological innovations have created the use of lasers in different applications

Laser light is not visible, though our technological innovations have created the use of lasers in different applications like manufacturing, medicine, and welding to create efficiency. However, lasers have biological effects if accidentally or intentionally monochromatic laser beam collides with cells of a living organism. Researchers have carried out experiments to establish the extent to which lasers are able to affect human tissues with little discovery. Strong effects of laser collision can cause laser-induced shocks and dire bubble formations in an individual, which can cause death. Lasers have an effect on the eye that is, if monochromatic laser light encounters the cornea, blindness can occur. Shock waves have an effect, especially that which involves forming radicals within white and red blood cells. Biologically, if the light of high intensity and wavelength collides with lymphocytes, there is massive damage to cells. The extent and effectual smash-up are in relation to pressure and the number of pulses emitted at an instant (Karman et al, 1999, pp. 135-138).
