What is the degree of vision of 7 00 and 7 75

150 and 200

If it is a decimal eye chart, it is converted to a five-point eye chart, and the general myopia degree (such as degrees) is said according to the diopter, and the diopter of 1 is defined as the light rays passing through the lens to form a focal point one meter behind the lens. Denoted by d, the focal length f formula is d=1 f.

If the focal length of the lens is meters, then the diopter of the lens is 1, and it is customary to call this 200 degrees. The same diopter does not mean that the vision cannot be changed, so if the eye is myopia, you can use healthy and reasonable interventions, reasonable and moderate use of the eyes, and develop good eye habits, which may restore the vision.

This is the myopic diopter, one is 700 degrees, the other is 725 degrees, pay attention.

You'd better go to the hospital to check, it should be around 200-300, I'm now nearsighted at 275 degrees, if you need glasses.

Hello, once the eyes begin to appear blurry, it is myopia, and the vision should be about 75 degrees to degrees of myopia.

They are 125 degrees of myopia and 75 degrees of myopia.

Myopia is a type of refractive error. When the eye is in a relaxed state of accommodation, parallel light rays enter the eye and focus in front of the retina, which causes a clear image to be formed on the retina, which is called myopia. At this time, the refraction examination will indicate the degree of myopia, such as 50 degrees of myopia, which is usually recorded as""。

In the state of relaxation of eye accommodation, the external parallel light enters the eye, and its focus falls on the retina, forming a clear image, which is called emmetropia; If the focus does not fall on the retina, it is called nonemmetropia, which is refractive error.

In recent years, the incidence of myopia in China has shown a significant upward trend, and myopia has become a major public health problem affecting the eye health of Chinese people, especially adolescents. This most common ophthalmic disease is listed as one of the three major diseases in the world, and the incidence of myopia in China's population is about 33%, which is twice the world average (22% of the total population).

Generally speaking, if the myopia is less than 300 degrees, it is pseudomyopia, and you can still have a chance to recover by protecting your eyesight.

Hello, it means 125 degrees of myopia, which means 75 degrees of myopia. There are positive and negative powers, a positive power is farsighted, and a negative power is myopia. Hope my answer can help you Thank you.
