The eye is the organ of vision that perceives light and converts it into electrochemical impulses in the nerves. The more complex eye is an optical system that can collect light from the surrounding environment, adjust the intensity of the eye through the iris, focus it with an adjustable lens, and project it to the light-sensitive retina to produce an image, which converts the image into electrical signals and transmits it to the visual system and other parts of the brain through the optic nerve. Eyes can be divided into ten different species according to their ability to distinguish colors, and 96% of animals have complex optical systems.

Among them, the eyes of mollusks, chordates and arthropods have the function of imaging.

In many vertebrates and some mollusks, the eye imprints light by projecting light onto the light-sensitive retina, where light is received and converted into signals that are transmitted to the brain through the optic nerve. Usually the eye is spherical, filled with a clear, gel-like substance, with a lens for focusing, and usually an iris that controls how much light enters the eye.

2. Vision care:

1. Vision-enhancing vision care: early prevention of diseases that may affect the development of visual function can be done by means of glasses and strabismus correction to help maintain the development of visual function.

2. Visual care and vision care: It is mainly to maintain a well-developed visual function state, prevent and treat myopia and pseudomyopia in a timely manner, and restore vision to the original development level through automatic telescopes, vision optimization systems and other measures.

3. Preventive vision care: mainly to prevent the occurrence of blinding eye diseases, such as the prevention and treatment of congenital cataracts, the prevention and treatment of eye trauma, etc., which can be alleviated by drugs and surgery.

4. Symptomatic vision care: prevention and treatment of unexplained adverse eye symptoms, such as eye fatigue, itchy eyes and other symptoms, can be relieved by eye massage, vision exercises, etc.

1. Carrots.

Vitamin A is one of the essential elements for the eyes. Vitamin A includes carotene, the most important substance for maintaining eye health. Carrots are the best choice for vitamin A intake.

Eyes are needed to read and read, to read and read, to look at pictures and paintings, to see people, to enjoy beautiful scenery, etc. The eye can distinguish between different colors and brightness of light and convert this information into neural signals that are transmitted to the brain.

2. The human eye is approximately spherical and located in the orbit. The average anteroposterior diameter of a normal adult is 24 mm, and the average vertical diameter is 23 mm. The anterior end protrudes 12 14 mm outside the orbit and is protected by the eyelids.
