I have 4 9 vision in both my left and right eyes, so what should my diopter be I m 13 and don t hav

In general, yes. According to what you said, both eyes and left eyes, that is, both eyes should have binocular vision at the same time is better than monocular), and then you ask what is the refraction? This question is not very relevant, because how much vision you see is not comparable to your actual diopter.

Let's start with diopters: diopters are the degree to which they can change the focal distance of light (when you are taught physics in high school). General refraction (the smallest unit is 25 degrees), every 25 degrees can be increased by one or two rows of optometric targets, according to the requirements of optometry, monocular and binocular is the standard.

And if you have both left and right eyes, then in my experience, you estimate that it is only 25 degrees, and it is also possible that astigmatism. Astigmatism is mainly a refractive irregularity of the eyeball, resulting in an incomplete refraction on the retina.

If it is a good eyesight, the diopter should not be greater than 100 degrees (special cases are not excluded). No glasses are required.

The diopter is the power of the glasses (enough popular...)

Addendum: We're the same age.

We usually say "degree" and diopter are different, but it can be converted, verbally 300 degrees, diopter is degree, 100 degrees is equal to 1 diopter. 375 degrees is the diopter. The refraction shows the diopter, and if you move the decimal point to the right by two places, you will be 100 times larger.

This is not directly related to the degree. Someone 300 sees, someone 750, sees. There is no conversion.

But the vision standards stipulate that the above is normal vision, you may have a little pseudomyopia, it is better to see an ophthalmologist, there is still hope. I went to see it again and the doctor told me to get glasses. I'm from here, so believe me.

Correction power 25. Because the minimum difference between lenses is 25. There should be no need to correct your power of this kind. It's considered normal.

Commonly used methods to correct myopia are:

1. The eyes should not be overworked to maintain sufficient sleep, and it is best to wear glasses and do correction to prevent further deterioration.

2. Insist on doing eye exercises every day and massaging relevant acupuncture points, which can relieve the fatigue of eye disturbances.

3. When looking at the computer, often blink actively, because people's eyes will not blink automatically in front of the computer screen, resulting in dry eyes.

4. Take a 10-minute break every time you use the computer or work in close proximity for 1 hour to relieve visual fatigue.

5. Rest more, sleep also has an impact.

Those under the age of age should take vision nutrients in a timely manner. It is recommended to take Leyan Vision Nutrients, two Huai Li open packs a day, and insist on taking it for a period of time, the myopia lead age will be reduced, and the vision will be improved.

Visual acuity and diopter are two different concepts, and there is no inevitable law between the two, that is, neither can you infer how many degrees of myopia you have based on your vision, nor can you judge the degree of vision by the degree of myopia!

The specific prescription should still be accurate for the optometry audition. But the landlord's eyes should be a serious refractive error.

Hello! There is no direct correlation between power and unaided visual acuity, for example, a person with 100 degrees of myopia and a person with 300 degrees of myopia may have both unaided vision. Your eyesight, which may or may not be myopia, is a loss of vision caused by eye fatigue caused by long-term viewing, and this vision can be restored.

If you want to determine whether it is myopia and how many degrees of myopia there is, it is recommended to go to the hospital for a dilated pupil examination, (dilated pupils with eye drops, and check your vision after dilated pupils) This is the most accurate! According to the results of the examination, if it is true myopia, it is recommended to wear glasses in case of high vision requirements such as driving, and if it is pseudomyopia, pay attention to rest, and it will recover.

Hope it helps!

Problem analysis: Hello, myopia and vision are not very proportional, because everyone has different ciliary muscle accommodation, so the same degree may be different vision is also normal.

Suggestions: Usually about a myopia, the vision should be around the right, yours belongs to a relatively low level, it can only mean that your adjustment is relatively poor, as long as you wear glasses reasonably, there is no big problem. Therefore, it doesn't matter if the vision test is corrected, but it can be corrected by wearing glasses of more than 100 degrees.

Myopia is a type of refractive refraction. Judging by your eyesight, it is estimated that you are already wearing glasses.

Think about how many degrees of glasses you wore when you first started myopia, and after a period of time, the prescription was not enough, and your vision decreased, and you had to change your glasses again, forming a vicious circle. This condition is entirely due to poor eye hygiene habits.

Myopia glasses are only compensatory correction, which is used to solve the problem of unclear vision, and wearing glasses at close range will increase the burden of eye accommodation, coupled with not paying attention to the distance between the eyes and using the eyes for too long, which will further promote the deepening of myopia. Generally, until the age of 18 or even 20, the development of the eyeball is fixed, and the degree of myopia will no longer deepen.

Generally, it is possible for young people with myopia to increase by 50-100 degrees per year, or even by 300 degrees. You can judge the consequences of this kind of continuation on this basis.

The fundamental solution is to develop good eye habits, avoid long-term close eye use, move your eyes more, blink more, see far, do more health exercises, go to outdoor activities, etc., my space has relevant content, you may wish to take a look, I believe it will be helpful to you.
