What is the degree of vision 4 0, what is the degree of vision of my 4 0

The corresponding power of visual acuity is 650 degrees, which is high myopia. Visual acuity is recorded in decimals, which is true myopia, and it is recommended to correct vision with glasses.

The eye chart and the corresponding prescription can be referred to the table below.

It cannot be converted, the results of the distance vision test table are the "visual acuity" you can see at the moment, and the power is the diopter measured by the instrument. One is similar to sensibility, the other is similar to reason. So, you also have to go to a professional institution or an eye hospital to have your refraction measured.

The eye chart and the corresponding prescription can be referred to the table below.

For vision of 20 5, the clarity of seeing an object at a distance of 20 feet is equivalent to 5 feet, which is equivalent to ordinary vision. It is 50 degrees of myopia lenses; It is 200 degrees of myopia lenses. For example:

He doesn't look at the eye chart without a mirror and only sees, so he needs to wear glasses for myopia of about 200 to 225 degrees, and he can almost see it after wearing the glasses.

Unaided vision is the vision before the glasses; Corrected vision is the vision that comes with glasses.

2. The corrected visual acuity of myopia can not be generalized, and the corrected visual acuity of mild myopia can reach more than 1 0, while the corrected visual acuity of patients with high myopia may not be able to reach 1 0

If your visual acuity is equivalent to a decimal value, you must wear 225-300 degree glasses.

The above is the answer from the experts! Hope it helps! Thank you!

It is about 500 degrees of myopia.

Generally over 5 years old, the international standard eye chart, logarithmic eye chart, is normal vision. The visual acuity of the logarithmic eye chart is equivalent to the visual acuity of the international standard eye chart.

However, when the refractive medium of the eye (such as cornea, lens, vitreous, etc.) becomes cloudy or there is refractive error (including myopia, farsightedness, astigmatism, etc.), the vision of the eye with good retinal function will still decrease.

Nudiity and power are not the same, you go to optometry Some people have a high degree but nude vision is not necessarily very bad, and some people have a low degree but poor nude vision I am 470 degrees, naked vision Some of my classmates are naked, only 200 degrees So it's hard to say, you are still a professional eye hospital to see, I saw it in Qingdao New Vision Eye Hospital.

Hello, everyone's eye condition is different, naked eye vision and myopia are not proportional, so you need to go to the ophthalmology department for detailed optometry to determine how many degrees of myopia you have.

Visual acuity and myopia are not the same concept, and the degree of myopia in visual acuity is about 400 degrees or more.

Go to the hospital and get it checked, after all, that's the authority.

It's myopia -410 degrees, so let's get glasses.

There is no fixed formula conversion for this, it is recommended that you go to a professional hospital for examination to see which method is suitable for **, early detection**.

If the diopter is not proportional to the naked eye's vision, the specific degree should be done for an optometry examination.
