The eyes work like camera lenses that focus on the film and resemble the cornea, the lens of the eye and the lens of the camera, while the retina resembles the film, all of which revolves around the ideal and perhaps behind all these functions a lot of information and details that we do not know from our eyes, The strangest of these facts is in a new episode of the "Know Your Body" series, according to the scientific website "Thoughtco".
- The eye behaves just like the camera in the sense that the image formed on the retina is reversed (upside down), and when the brain translates the image, it turns them automatically.
- Humans do not see ultraviolet light, but the retina can detect it. What prevents it is that the lens absorbs it before reaching the retina.
- Blind people who still have eyes can sense the difference between light and darkness, because there are special cells in the eyes that reveal light, but they do not participate in the formation of images.
- Each eye has a small point of blindness, this point where the optic nerve is attached to the eyeball, but not felt by the person.
- Doctors are unable to fully implant an eye, and the reason is that it is very difficult to re-link nerve fibers that are more than one million in the optic nerve.
- The color of the eye can change over time, mainly due to hormonal changes or chemical reactions in the body.
