Ask what is good for the eyes and what are the benefits of the eyes

Tell very seriously, insist on daily eye exercises. It is very effective, and eat some eye-replenishing foods, such as pork liver.

The eyes are important organs of the human body, and excessive use of the eyes, such as reading, lettering, embroidery, and watching TV and other activities for too long, can cause eye fatigue, general fatigue, and extreme mental tension;Malnutrition can also lead to vision loss.

Common symptoms of eye fatigue are headache, forehead swelling, and dry eyes.

To protect your eyes, in addition to paying attention to the combination of work and rest, do not read books and watch TV for a long time, do eye exercises regularly, and often eat some foods that are beneficial to your eyes, which can also play a great role in protecting your eyes.

So what are the foods that are good for the eyes?

Such as lean meat, poultry meat, animal offal, fish and shrimp, milk, eggs, beans, etc., which are rich in protein, and protein is the main component of the cell, tissue repair and renewal need to constantly replenish protein, food containing vitamin A is also beneficial to the eyes, when vitamin A is lacking, the ability of the eyes to adapt to the dark environment is reduced, and it is easy to suffer from nocturnal syndrome when it is serious.

Vitamin A can also prevent and ** dry eye disease. When you are deficient in vitamin A for a long time, you should take enough vitamin A every day to eliminate eye fatigue. The best** of vitamin A is the liver, cod liver oil, milk and eggs of various animals, plant foods such as carrots, amaranth, spinach, leeks, green peppers, red sweet potatoes and oranges, apricots, persimmons and other carotenes in fruits.

Foods that contain vitamin C are also good for the eyes. Vitamin C is one of the components that make up the lens of the eyeball.

If you are deficient in vitamin C, you are susceptible to cataract disease with cloudy crystals. Therefore, it is important to consume foods rich in vitamin C in your daily diet. For example, a variety of fresh vegetables and fruits, especially green peppers, cucumbers, cauliflower, bok choy, fresh dates, raw pears and oranges are the highest.

Rich calcium powder is also good for the eyes, and calcium has the effect of eliminating eye tension. For example, beans, green leafy vegetables, and shrimp skin are rich in calcium. Cooking methods such as roasted pork rib soup, pine fish, and sweet and sour pork ribs can increase the calcium content.

Remember to take good care of your eyes, because "eyes are the windows of the soul"!

1. The eye is the most important organ of the human senses, and about 80% of the knowledge in the brain is obtained through the eye. 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 lidal rock cover segment.

The eyeball includes tissues such as the wall of the eyeball, the intraocular cavity and contents, nerves, and blood vessels.

Eye: The eye is the most important organ of the human senses, and about 80% of the knowledge in the brain is acquired through the eye. Reading and reading, looking at pictures, looking at people, enjoying beautiful scenery, etc.—all of these things need to be done with the eyes.

The eye can distinguish between different colors and the brightness of light, and convert this information into nerve signals that are transmitted to the brain.

The human eye is the benchmark for the magnification of the telescope, that is, the magnification is 1, and the aperture is the size of the pupil of the human eye, which changes with the change of light intensity, generally fluctuating between 2 and 7 mm.

Imaging Principle:

The eye changes the focal length of the lens by adjusting the degree of curvature of the lens to obtain an inverted, reduced image. The farthest point that the eye can see is called the adjusted far point, and the far point that the eye can see is at a very far distance; The closest point that the eye can see is called the adjustment point, and the distance between the two points is called the adjustment range. The near point of the normal eye is about 10 cm from the eye.

Increasing the time spent outdoors as much as possible can prevent the occurrence of myopia;

2. Reading, TV, computer or mobile phone, 30 minutes of eye time should be rested for about 10 minutes;

3. Maintain a good reading distance;

4. Maintain a good sitting posture when reading and writing, do not lie down to read, and do not read in a rocking car;

Fifth, the indoor lighting should be appropriate, not too bright and not too dark;

6. Regularly go to the ophthalmology department for eye examinations.

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.
