The eyesight is 5 0 on the left and right, but the eyes can t see clearly in the evening and morning

If you can't see, you belong to night blindness, and if you can't see clearly, it belongs to astigmatism, so yours is not night blindness, go and check your vision, it should be a little astigmatism. Hope it helps.

It should be caused by vision loss, pay attention to oral hygiene, and avoid eye strain.

1. The time of close eye use should not be too long, every 40-50 minutes, you should take a little rest for 3-5 minutes, and look into the distance to relieve visual fatigue.

2. Read and write, play with the computer, maintain a correct posture, the height of the table and chair should be appropriate, and the distance between the eyes and the reading materials should be about 33 cm.

3. Mix whole grains, meat and vegetables, eat more vegetables and fruits, and don't eat partially. Lack of vitamins in food is prone to night blindness and dry eye disease, and lack of trace elements chromium and calcium in food makes it easy to suffer from myopia.

Fourth, when reading and writing, the light should be moderate, not too strong or too dark, and the light should come from the left front, so as not to obstruct the vision of the hand shadow. The light should be soft, if it is incandescent, it should be between 25 and 40W, and it is not recommended to read in the sun. Because the intensity of light has a direct impact on pupil dilation, too strong light will increase the intensity of eye accommodation, aggravate the intensity of eye labor, and it is easy to cause myopia after a long time.

Generally, desktop lamps should be less than 40 watts.

5. Avoid reading while walking or reading in a walking car. Because the carriage is shaking, the body is shaking, and the distance between the eyes and the book cannot be fixed, the burden on the glasses will increase. Often, this is likely to lead to myopia.

6. Actively participate in physical exercise to enhance physical fitness. As the eyeball follows the target, the ciliary muscles continue to relax and contract, and the synergistic effect of the extraocular muscles can increase the blood perfusion of the eye, promote the metabolism of the eye, and thus reduce eye fatigue. Moreover, the quality of physical fitness is also closely related to the occurrence of myopia in children.

Malnourished and weak children are prone to myopia.

7. Insist on doing proper eye exercises. By massaging the acupuncture points around the eyes to enhance the blood circulation of the eye socket, improve neuronutrition, eliminate the excessive congestion in the eye, and achieve the purpose of relieving eye fatigue, it is conducive to the prevention and treatment of pseudomyopia in adolescents, and is a good way for adolescents to self-care their eyes.

8. Eat less candy and high-sugar foods. Too much sugar will produce a large amount of acidic substances in the blood, and the acid will combine with the salt in the body, especially calcium, resulting in a decrease in blood calcium, which will affect the toughness of the eye wall, make the eye axis easy to elongate, and promote the occurrence and development of myopia.

9. Regularly go to the eye hospital to check the eyesight, and if it is found, it should be corrected in time to prevent the progression of myopia.

10. Eat less sweets. Because sugar needs a lot of vitamin B1 to metabolize in the body, if you consume too much sugar, vitamin B1 will appear insufficient. Vitamin B1 deficiency can affect the growth and development of the optic nerve, leading to vision loss.

Excessive intake of sugar will also reduce the calcium in the body, weaken the elasticity of the eyeball, and promote the development of myopia.

Analysis: Hello, depending on the situation you provide, there is a high possibility of night blindness to be considered.

Suggestions: Night blindness is commonly known as "blindfolding", which is called night blindness when it is difficult to see clearly and move in a dimly lit environment at night. The root cause of night blindness is the lack of raw materials for rhodopsin synthesis in retinal rod cells or the lesions of rod cells themselves, which are mostly caused by vitamin A deficiency.

Analysis: From your condition, after all, you used to have vision, so it cannot be ruled out that your visual fibrillation has decreased and you have refractive error.

Suggestions: should be the refractive error caused by excessive use of the eye, it is recommended to go to a professional optometry institution to check the eyesight, if the vision can still be seen, then it should be the recent eye fatigue caused by excessive use of the eye, it can be recovered by rest, if there is refractive error, you need to wear glasses to correct, I hope it will help you.
