Application
Of all the risks caused by lasers, eye damage is the most serious. After all, vision loss is a serious incision, so more careful consideration should be given to how eye damage occurs and how to prevent it. When light hits the eye, the cornea and lens act as a magnifier. According to the functional principle of magnifying glasses, they concentrate light on the retina (in the back of the eyeball). From here, the stimulus is delivered to the brain, where it is processed into an image. These three parts of the eye (cornea, lens, and retina) are the most vulnerable to damage from laser radiation.
