The correction option is LASERS NEAR INFRA RED AND VISIBLE BEAM LASERS.
Human eyes are very sensitive to laser rays. These lasers cause biological damage in the eyes due to their high temperatures and the photo chemical reactions. The degree of damage caused depend on the wavelength of the ray involved.
