The visual acuity of the left eye is 0 3, and the visual acuity of the right eye is 2 0 How to get i

You don't know anything about eyesight. It is the best vision, the degree of myopia has nothing to do with the naked eye, it must be 200 degrees higher than 100 degrees. Myopia is usually blurry vision from a distance.

The vision may be farsighted, and you can see far away, but you may not be able to see clearly near it. Unaided vision: Myopia, vision without glasses.

indicates unaided distance vision; 100 degrees indicates the degree of myopia, and there is no numerical correspondence between the two.

Generally, if a normal person's distance vision is normal, you are fine.

Better than eyesight, these are two different marking methods! It usually means that you can see a point of view clearly at a meter, that is, you can see a point of view at a meter.

Got it! Have a great day!

That's the best eyesight pull, not satisfied.

The visual acuity is equivalent to, about 450 degrees.

In fact, the measured eye chart logarithmic visual acuity and naked eye visual acuity are not directly related to what we usually call the number of degrees of the eye (eye refraction), like myopia 200 or 700 degrees, because our human eye accommodation is not the same. To know the exact prescription, you need to go to the ophthalmology department of the hospital for routine vision examination and computerized refraction examination.

Eye vision in and above is normal vision, and can achieve excellent vision, such vision only needs daily protection to not decline on it, the general common methods are:

1. When reading a book or looking at the computer, don't keep staring, you should turn your eyes more and exercise more, your eyes are like our bodies, they need to be exercised.

2. Look at more green, if there are green plants nearby, you can look at green plants from time to time, green has a soothing effect on the eyes. I often read a book or look at the computer at close range, and I need to occasionally look into the distance to relax my lower eye muscles.

3. Do eye exercises: eye exercises are very helpful for relieving eye fatigue and dryness, often read books or look at the computer can do eye exercises every two or three hours, massage eye acupoints.

4. Blinking: Blinking can relieve eye fatigue and dryness, which is very beneficial to the eyes, and this method can be done anywhere at any time, which is very convenient.

5. Ice packs for eyes: Before going to bed, applying ice packs to the eyes can not only reduce swelling, but also help relieve eye fatigue.

6. Don't read in a dim place, don't turn off the light to look at the computer, and don't read in the backlight or in the sun.

7. Eat more purple fruits and vegetables, as well as fish.

8. Regularly supplement vision nutrients, and general doctors recommend oral eye vision nutrients, and insist on taking them for a period of time every year, which can protect vision and prevent the occurrence of myopia.

The eyesight is currently the best strength, you see that the eye chart on the best people, my child's poor eyesight only arrived, too envious of your eyesight, but in good eyesight to protect well, now use a large amount of eyes, but also regularly check the eyesight. I have been leading the inspection without charge, and the examination is very good, but the child is disobedient and has poor eyesight.

The current vision is the standard of the previous vision. In other words, the eyesight is very good and there is no problem.

Vision is to look at the eye chart at a distance of 5 meters to see the row of E direction, the eyesight is very good, the pilot's eyesight is superb.

It is naked eye vision, vision that has not been corrected by lenses, generally normal people are in between, and the vision is lower after myopia, and it can be achieved by wearing glasses with appropriate prescriptions or to reach normal vision.

Usually, it is said that "it is visual acuity, that is, the number represented by the first few lines can be seen in the international standard eye chart," which means that you can see the 13th line, which is just a test mark.

And "400 degrees" and the like refers to the diopter, which is the reciprocal of the focal length f of the refractive system, and the relationship between the "degree" and the diopter when we wear glasses is: 1 diopter 100 degrees.

However, there is no conversion formula between visual acuity and power, because visual acuity and power are not proportional, for example, if someone has a myopia of 800 degrees, they can see it when they look at the distance vision chart, while another person has a myopia of 300 degrees, and they can only see it when they look at the distance vision chart.

The visual acuity in the old eye chart is equivalent to the visual acuity in the new eye chart, the reference myopia degree should be between 300-350 degrees of vision, and in the new eye chart, it is equivalent to the visual acuity of yes, the corresponding degree is about 450 degrees, which belongs to moderate myopia.

Myopia is the most common eye disease among children in China, and the rate of high myopia in mainland China is much higher than that of children in other countries and regions.
