What harm does laser surgery do to eyes?
There are three kinds of laser damage to human eyes: \x0d\ 1. The damage of strong light to the nerves of the eyes, laser is a kind of high-density light energy, and it is a single wavelength, that is, monochromatic light. A weak laser aimed at the naked eye can be very dazzling. Slightly high-power laser will temporarily blind the eyes, and high-power light intensity will directly hurt the nerves of the eyes, leading to blindness. This is also for visible light, infrared or ultraviolet invisible light, which is invisible to human eyes and has no sensory stimulation to human eyes. \x0d\2. When the light energy reaches a certain level, it will produce high temperature to the object and directly burn the eyes. When the laser power reaches a certain level, the steel plate can be vaporized instantly, not to mention the eyes. This should be easy to understand. \x0d\3. Some specific lasers have a particularly strong absorption effect on specific materials, such as near-infrared lasers with a wavelength of 1064NM. The laser characteristic of this wavelength band is that it has a particularly strong absorption of water. If you directly irradiate people's eyes, it will absorb water from the eyes, which is very harmful to the eyes. \x0d\ Actually, the laser does not touch a specific object, so there is no radiation. For the human body, the main harm of laser is the sensory stimulation to the human body, the burn caused by high energy and the absorption of water with specific wavelength.
