Visual acuity in the left eye is 5 3 and visual acuity in the right eye is 4 9

The landlord's binocular vision has a certain anisometropia.

Staying up late with the eyes is easy to form visual fatigue, the eyeballs are in a state of adjustment for a long time, and they are not relaxed, and they will definitely have an impact on their vision after a long time!

How old is the landlord? It's good to say that if you are still a teenager, you should pay attention, your eyeballs have not yet developed, and you have to take good care of your eyes! The eyes are the windows to the soul, otherwise there will be a lot of inconvenience in the future!

If it's a girl, bangs often cover the eyes, which will also cause vision to deteriorate and appear uneven!

Eye exercises are very good, can relieve eye fatigue, but the wrong method will be counterproductive, you can go to a larger optical store, there is a heat therapy instrument, (we do it here for free) to relieve eye fatigue, 15 minutes to significantly improve the naked eye vision, long-term persistence!

Also, don't stay up late!

Good luck with improved eyesight!

It's okay to take a break...Don't be in front of the computer for long periods of time

Generally, it will not recover, pay attention to maintenance, and the difference is still not much, even if it is myopia, I am now, it is very good to do eye exercises, look at the computer for a while to rest for about 10 minutes, eat some cod liver oil and other good things for the eyes.

My mother told me that my fifth master was over 80 years old, and his eyes used to be short-sighted, and he couldn't even read the newspaper, and then he insisted on doing eye exercises every morning, but now he doesn't talk about the newspaper, and his eyes are not myopic at all, and his health is very good, and he has never heard of him being sick.

The unaided visual acuity value is about 300 to 350 degrees, which belongs to medium and low myopia, but we must pay attention to the protection of the eyes to prevent further decline in vision. First of all, you should go to a regular optical store with myopia glasses to correct your vision; At the same time, it is necessary to pay attention to eye hygiene and do not use eyes for a long time; Don't play with your phone or read a book in a place that is too dark; Doing eye exercises every day can effectively restore your eyesight.

Hello, myopia and unaided visual acuity cannot be directly calculated, and there is no direct conversion relationship between the two. The prescription is measured by optometry, while unaided vision is when you see an eye chart without glasses. There is no strict correspondence between the two.

You can check your eyesight first, and there is no necessary correspondence between visual acuity and myopia.

Therefore, it is necessary to determine the exact degree of myopia after the hospital ophthalmology department dilated eye refraction, and then wear appropriate glasses according to the follow-up situation to correct the vision to a normal level, reduce the burden on the eyes, and prevent the prescription from deepening.

The sum of visual acuity refers to the determination of the visual acuity level of the eye by a logarithmic eye chart as sum. Normal visual acuity standard in Kairu Hall: Visual acuity that can distinguish 1 perspective is the standard of normal visual acuity, which is recorded as equivalent to visual acuity recorded in decimal records and 6 6 or 20 20 visual acuity recorded by fractions.

Logarithmic eye chart printing specifications:

1) The distance vision chart is printed on offset printing paper, with a quantitative amount of more than 70g m2 and a whiteness of not less than 85%. The distance vision chart uses a 5-carat (777mm 217mm) format of 787mm 1092mm paper, and the allowable deviation is 3mm. The distance vision chart is arranged from top to bottom by size in 14 rows of optoscopes.

The row spacing is 24mm.

2) The near eye chart is printed on white cardboard, with a quantitative amount of more than 200g m2 and a whiteness of not less than 90%. The near eye chart is 145mm 270mm in a three-fold format with a permissible deviation of 2mm. The near eye chart is divided into three segments from right to left, and the 23 rows of optographic indicators are arranged from top to bottom in order of size.

It's 100 degrees, it's 450 degrees.

The left eye 100 is also so-so.

It's very mild myopia, but the right eye is really myopic and must need glasses.

It's not easy to deepen.

The left eye is not considered myopia, and the right eye is a little myopic but the degree is not high, only about 50 degrees, so it is not recommended to wear glasses.

Let me correct you, from your tips above, it can only mean that your brother's eyesight is not good, but it can't necessarily be said to be myopia.

Astigmatism and farsightedness can also lead to this.

So, take a picture on the computer refractor, and you will know.

Is it naked eye vision that gives you?

The left eye is okay.

The right eye is more nearsighted.

However, the specific prescription needs to be tried on.

Not absolutely.

The visual acuity of the right eye is yes, and the visual acuity of the left eye is left and right.

The eye chart conversion is as follows:

The standard logarithmic eye chart and decimal record eye chart are as follows.
