In many vertebrates and some mollusks, the eye projects light to the light sensitive retina for imaging, where light is received and converted into signals and transmitted to the brain through the optic nerve. Usually, the eyes are spherical, filled with transparent gelatinous material, and have a focused lens. Usually there is an iris that controls the number of rays entering the eye.
Brief introduction of eye organ

Imaging principle of eyes
Let’s introduce the structure of the eye through the soft enamel pins of the eye. The eye can change the focal length of the lens to obtain the inverted and reduced real image by adjusting the curvature of the lens. The farthest point that the eye can see is called the adjusting distance point, and the farthest point that the eye can see is very far away; the closest point that the eye can see is called the adjusting distance point, and the distance between the two points is called the adjusting range. The close point of the normal eye is about 10 cm from the eye. The wall of eyeball is mainly divided into three layers: outer, middle and inner. The outer layer is composed of cornea and sclera, also known as fibrous layer. The first 1 / 6 is transparent cornea, and the other 5 / 6 is white sclera, commonly known as “eye white”. The outer layer of the eyeball maintains the shape of the eyeball and protects the tissues in the eye. Cornea is the most sentinel entrance to receive information. The cornea is a transparent part of the anterior part of the eyeball through which light can be transmitted into the eyeball as a transparent wafer. The cornea is slightly oval and slightly protrusive.
