What is the visual acuity of 1 2, and what is the equivalent of visual acuity 1 2

If the visual acuity is converted to myopia, it is about 200 degrees.

Visual acuity refers to visual acuity, which is normal vision and has no prescription.

Visual acuity is divided into near vision and distance vision, distance visual acuity, refers to the smallest visual target that the subject can see clearly at a distance of 5 meters from the eye chart, visual acuity and above, is normal vision, the following is considered to be defective vision, near visual acuity refers to 33cm away from the eye chart, visual acuity and above, is normal vision.

The power of the myopic eye refers to the refraction, and the relationship between visual acuity and the power of the myopic eye is that the worse the visual acuity, the higher the power of myopia.

Decimal records eye charts.

It is usually said that "it is eyesight, which is the international standard."

The number represented by the first row can be seen in the eye chart.

Word, "is to be able to see line 13, which is just one."

inspection criteria.

And "200 degrees" and the like refer to the diopter, that is.

The reciprocal of the focal length f of the refractive system, we have glasses.

The relationship between "degree" and diopter is: 1 diopter.

Luminosity 100 degrees.

But there is no conversion formula between visual acuity and prescription, because.

Because visual acuity and power are not proportional, for example, some.

The degree of myopia is 800 degrees, and it is possible to look at the distance vision chart.

See, while the other person has a degree of myopia.

300 degrees, looking at the distance vision chart can only see.

Monocular vision is normal vision, and it is very likely to be emmetropic or a little low-degree farsightedness. It is recommended to pay attention to the use of eyes to avoid vision loss caused by excessive fatigue and other reasons.

There is no necessary relationship between visual acuity and power, for example, some people have 100 vision, some people have 300, and there is no simple linear function relationship between visual acuity and power.

Visual acuity is the smallest angle of view that can be resolved by human retinal 2 cells, and according to this standard, it can be seen from a distance of 5 meters.

Your eyesight is good.
