The Eye Structure
how it works
How does the Human Eye work?
The cornea also has other parts of the eye that support it. One is the lens (crystalline).
The (crystalline) lens is a transparent structure that, along with the cornea, helps to refract to the retina.
Light coming by the cornea and crystalline lens then reaches the retina, the light-sensitive inner lining of the back of the eye. The retina acts like an image sensor of a digital camera, converting optical images into signals. The optic nerve then transmits these signals to the visual cortex, the part of the brain that controls the sense of sight.
Eye glasses are used to correct eye sight problems. Eye glasses have different angles dependent on how bad the person's eye problem is.
The Human Eye
There are six main muscles in the eye that control the motion of it. The most important parts of the human eye are the iris, cornea, lens, retina, conjunctiva, the macula, and the optic nerve.
Correcting Eye Problems
There are many other less common problems such as burning eyes, paining eyes, allergies in the eye, black eye blehpharitis, A-Z letters eye symptoms, eye diseases in general and even eye cancer.
Most of these problems can't be fixed and be back to normal but there are many equipment that can help stop it or temporarily fix it while in use, such as eye glasses and contact lens.
It is very easy to get eye problems but very hard to try fix or help so easy tips and habits can save your eye sight and bad habits can ruin them very quick. One of the most common bad habits is using looking at a screen, book or object too close a lot. This can cause short sight easily if you do it consistently.
