Detailed Solution

The Ultraviolet rays are preferred in the application like LASIK eye surgery. The ultraviolet rays are used because of their high precision as they can be focused in a very narrow beam.

LASIK uses an excimer laser (an ultraviolet laser) to remove a thin layer of corneal tissue. This gives the cornea a new shape so that light rays are focused clearly on the retina.
