Can I go outside without my eyes if I am 400 degrees nearsighted?

Wearing glasses is a matter of habit and need.

You have to look hard at things in the distance, then the eyes will hurt, the retina will be more compressed, then it will be more myopia, so you have to bring. This is very clear: as long as people with eyes wear glasses in class, the blackboard is small to prevent overuse of eyes and deepen myopia.

If you don't look at things outside and don't squint at the small slit, don't wear them, and you can't remove your glasses when you wear them. But most of the time you squint your eyes, you have to take it, because then your eyesight will drop directly, and you will have to wear it in the future, so it's better to wear it early and control the power.

It's best not to wear it, usually do health exercises, and eat more foods containing anthocyanins that are good for your eyes, such as grapes, blackberries, figs, cherries, beetroot, eggplant, purple sweet potato, black dragon ball, black potato, blood orange, red cabbage, blueberry, cranberry, strawberry, mulberry, hawthorn skin, dragon fruit, perilla, black (red) rice, etc. Because anthocyanins can accelerate the synthesis and regeneration of rhodopsin on the retina, the retina can adapt to changes in light and improve the eye's ability to distinguish in dark places. It can enhance the sensitivity to dark and low light.

400-degree glasses can not be easily removed, it is recommended to wear them

If you don't wear glasses at this level, then you can't see clearly, so it is recommended to wear glasses.

Also note:

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. In addition, it is also necessary to pay attention to regular supplementation of eye vision nutrients, not from the nutrients required by the eyes, enhance the anti-fatigue ability of the eyes, and better protect the eyesight.

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.

Hello, myopia of 500 degrees is moderate myopia, and it is recommended that you wear glasses regularly.

Myopia of 500 degrees, generally speaking, without wearing eyes, seeing things in daily life at work and study will cause blurring, and there will be a situation where you can see clearly in and far away, so it is recommended to wear glasses for daily work, study and other items.

Wearing glasses can be determined according to your specific situation. If you look at things. If you need to see something small, you have to wear glasses.

If you. Don't look at things, just look at some big buildings around you or something. You don't need to wear glasses.

However, with nearsighted glasses. It is still more convenient to see objects and see more clearly. Because myopic eye glasses can also protect vision from not deteriorating.
