What is the degree of 0 5 eye, and what is the degree of myopia of 0 05?

Hello, the eye can't be sure if it's caused by refractive error, and even if it's caused by refractive error, there's no way to determine how many degrees it is. The common causes are keratitis, uveitis, cataract, glaucoma, retinal optic nerve lesions, if the above eye diseases are excluded, the physical examination does not find other abnormalities, then it is necessary to consider refractive error, visual acuity is, the degree of refractive error, it can be myopia, myopia astigmatism, farsightedness or farsightedness astigmatism, and may be mixed astigmatism. It must be determined through a medical vision.

Nakedness has nothing to do with power.

To do laser surgery, you need to be over 20 years old, the prescription has not increased within 2 years, and the corneal thickness is required. The main thing is that it is very risky and needs to be carefully considered!

Because the principle of the laser is to cut off a piece of the corneal surface directly to reduce the power, but if the power is too high, it cannot be completely corrected. There is also a certain possibility that the cornea will grow on its own. And because the cornea is thinner and brittle, you can't accept the impact of external forces, if you don't exercise in the future, if you are sure that you will not rub or collide with others in the rest of your life (fight), and if you don't have surgery for your eyes for the rest of your life, you can consider doing it.

Even if the surgery is done,

That's a matter of sight, how many degrees you can use to measure, about 200-250.

There is no absolute relationship between vision and power. The power is not proportional to the unaided visual acuity, 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 can only see it when they look at the distance vision chart. What is said is visual acuity, that is, the number represented by the number that can be seen in the first row of the international standard eye chart, that is, the number that can be seen in line 13, which is only a test standard.

200 degrees 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. Vision is a feeling that is synthesized by the cerebral cortex.

The power is a refractive problem, which is objective, and can be measured by both imaging and computer measurements. It can be simply understood that it is about 300 degrees. Low-grade myopia can be completely recovered with scientific cooperation**, but the key is to maintain it in the future, which requires effective maintenance.

Also, pay attention to eye hygiene and wish you good health.

This has little to do with the prescription of the glasses...

It is better to choose an eye hospital that only does myopia surgery.

Hello, first of all, let me explain to you that visual acuity and diopter are two different concepts. There is no conversion between them. Vision is only an approximate screening. What you have mentioned above is only a visual acuity value, and the exact degree must be determined by dilated refraction.

Myopia and visual acuity are two different concepts. The prescription is measured by refraction, while visual acuity is how you see the eye chart. There is no correspondence and conversion between the two.

To find out if you are currently nearsighted and your exact myopia degree, you should go to the hospital's eye department for a formal dilated eye examination.

At rest, the parallel light from infinity passes through the refractive system of the eye, and then converges in front of the retina to form a focal point, and on the retina, it forms an unclear image of distant vision that is significantly reduced, but near vision is still normal.

Suggestions: The above power does not need **, it belongs to normal vision. Medigo keratoscope tells.

's visual acuity is about 50 degrees or 100 degrees.

Visual acuity and diopters are not equal one-to-one. The exact amount is only known by optometry. Don't just wear glasses, and don't borrow glasses from others.

If your vision has only recently declined, it is likely to be pseudomyopia. Pay attention to rest, exercise outdoors, often look at the distance, don't stay in the classroom between classes, do more eye exercises, pseudomyopia can be recovered.

Based on personal experience, the prescription of glasses is about 300 (I remember that there seems to be a formula to calculate it). This is somewhere between true myopia and pseudomyopia. You need to take good care of your eyesight. Try Violet One Eye Fatigue Relief Capsules.

Visual acuity can not be clear how many degrees, the value of the detection of visual acuity and the value of the power can not be directly converted, but the visual acuity should belong to the standard vision, there may be no myopia, if you are not at ease, it is recommended to take the child to a regular ophthalmologist for eye testing, and then see if there is myopia, and then test the prescription, and wear appropriate glasses in time for correction.

Me, but the prescription of the glasses is around 175-200.

You can judge by me.

Low naked eye vision does not mean myopia, going to the hospital for optometry is the most accurate, and if it is a child under seven years old, the eye development is not perfect, and the naked eye vision is also low.

e, my right eye, 125 degrees, astigmatism 50 degrees, I don't know if it's not.

It is a standard of vision, on the Chinese logarithmic eye chart, from all the way to, even, the Chinese vision standard is that the above is normal vision, vision or vision, does not represent how many degrees, vision and power have no direct correlation. However, there is a correlation between this, and the worse the vision, the higher the degree of myopia, but there is no exact consistent correlation. For those who are more sensitive, 50 degrees and 100 degrees of myopia, their vision may be reached, but some people have better adjustment ability, and they may have 300 degrees or even 400 degrees of myopia, and their naked eye vision can still be reached.

Therefore, there is no complete scientific correlation between the degree of unaided visual acuity and the degree of myopia. It usually refers to the results of eye chart screening, also called naked eye vision, and the result obtained by computer refraction is the refractive power, and there is no direct correlation between the two, so if you want to know whether you have refractive error and refractive error, you can go to a regular hospital for optometry examination, only in this way can you get relatively accurate results, and the same naked eye vision refraction results may be different in different people.

For normal adults, normal vision should be above and above, and there are many causes of low vision, usually including refractive error, amblyopia, fundus diseases, etc., and the plan for each disease is different.

Visual acuity and myopia are both 200 degrees and 300 degrees respectively

Normal vision is at least there, so it is abnormal to be below it, so this power should still be paid attention to and corrected in time.

1. According to the vision situation, if you need glasses for correction, then you must go to the hospital for accurate optometry, and then wear appropriate glasses.

2. Correct daily bad eye habits and pay attention to developing good living habits.

3. Insist on doing eye exercises every day.

Fourth, timely supplement the eye vision nutrients to supplement the nutrients needed by the eyes, so as to better control or improve the myopia of the eyes.

5. Have a certain amount of outdoor activities every day and see more green plants.

6. Check your eyesight regularly.

Although, the higher the degree of myopia, the worse the distance vision, there is no strict proportion. Generally speaking, if you are nearsighted above 300 degrees, your distance vision will not exceed; 200 degrees in between; can be reached, and sometimes it may be better.

Those below 300 degrees are mild, those with 300 600 degrees are moderate, and those above 600 degrees are high.

Ways to improve your eyesight:

1 Do eye adjustment exercises. Look for a piece of grass or a tree 10 meters away and look intently for 25 seconds to identify the outline of a piece of grass or leaf. Then place your left palm a little more than 30 cm in front of your eye and read the line from beginning to end for about 5 seconds.

Look at the mudra, then gaze into the distance, then look at the mudra again. Repeat 20 times a day for 10 minutes each time.

2.Do eye exercises every day and massage the relevant acupuncture points in the eyes to relieve eye fatigue.

Eat more foods that contain vitamin A, such as carrots, spinach, cod liver oil, etc. It mainly supplements vision nutrition and enhances the ability of eyes to resist fatigue.

4. The eyes should not be overworked, to maintain enough sleep, it is best to wear glasses and do a correction** to prevent further deterioration.

5. Develop the best sitting posture, that is, the arms are straight and the chest is straight; Correcting bad habits includes lowering your head, lying on your stomach, looking at what's on your back, and staying up late.

The eyes are about 400 degrees of myopia, which is considered moderate myopia.

Commonly used methods to correct vision for moderate myopia are:

1. Put an end to over-looking close, reading and writing homework and other things that are close for a long time.

2. Develop the best sitting posture, that is, read and write with your chest and arms straight, and hold the pen correctly.

Note: The main purpose of holding the chest and straight arm is to keep the distance between the eyes and the desktop when reading and writing, and the incorrect posture of holding the pen will cause the eyes to be misaligned, so parents should always supervise their children.

3. Strengthen outdoor sports. It is required to exercise outdoors for two hours a day, running, playing ball, martial arts, swimming, gymnastics, etc.

Note: Outdoor exercise, improve physical fitness, physical health, and improve immunity; In the same way, if you strengthen exercise, your ability to resist myopia will also improve. Moreover, with outdoor sports, the eyes can look far away and enhance the sensitivity of the eyes.

4. Do far-sighted eye adjustment training, including: myopia prevention and treatment training exercises, eyeball-turning, frequent visual acuity measurement, and frequent look up at distant targets.

Note: Turning the eyeball, 2 second circles, clockwise and counterclockwise 60 circles each, increase blood circulation, measure vision, improve the ability to see far, exercise eye sensitivity, twice a day.

Myopia is generally limited to 300 degrees, and below 300 degrees, you will not squint when you are outdoors, and you will see things clearly and will not be blurred, so it is not recommended to wear glasses. It is only recommended to wear it when attending class, watching TV, and watching the computer.

However, above 300 degrees, you don't feel like you're squinting, but when you actually see things blurry, you use more adjustment to see things in the distance. In this way, according to the blurring theory of ophthalmology, your myopia will be accelerated, and it is easy to form astigmatism. The principle of myopia deepening is that when you see things blurrily, the ciliary muscle of the eye needs to use greater adjustment force, and after a long time, the ciliary muscle will be fatigued and lose its elasticity, forming pseudomyopia, and over time, the eye axis will be elongated, forming true myopia.

Low-grade true myopia translates into moderate myopia below 600 degrees because the eye produces new fatigue and new pseudomyopia. This progresses to high myopia. Therefore, above 300 degrees, we recommend wearing glasses all day.

If you don't wear glasses and see things in a blurry state, myopia will only accelerate the development of myopia and form astigmatism faster. If the astigmatism is large, it is easy to get headaches, and it is more difficult to correct than simple myopia.

The eye may have a myopia degree of about three or four hundred, however, the value of the vision test can only detect the strength of the visual acuity, and can not be directly converted with the degree of myopia, and now it is not clear what the child's myopia is, it is recommended to take the child to do a detailed refraction test to be clear, if the diagnosis is myopia, you need to wear glasses in time to correct, and at the same time pay attention to the child's eye care to prevent the degree from deepening.

200 degrees.

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 called 50 degrees of myopia, and is 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).

It is inaccurate to judge the degree only by the eye chart, some people are more than 100 degrees, some people are more than 200 degrees, this still depends on the instrument to measure accurately, but it is certain that it is mild myopia. Myopia can be exercised by the stalk forest rejuvenation surgery, and it can be restored to normal vision in about two or three months, which is not a big problem.

There is no direct correlation between power and unaided visual acuity, for example, a person with 100 degrees of myopia and a person with 300 degrees of myopia may have both unaided vision. One by one, it may be myopia, or it may not be myopia, but the vision loss caused by visual fatigue caused by looking at the near place for a long time, and this vision can be restored.

It is better to choose an eye hospital that only does myopia surgery.

It's probably around 200 degrees, so it's best to do a detailed check-up first.

If the naked eye vision is shown differently in different people, some people may be caused by astigmatism, and some people may be due to myopia. Even if the vision loss is also caused by myopia, some people may be 100 degrees, some people may be 200 degrees, this is mainly due to the different adjustment ability of each person's eyes. Therefore, if there is vision loss, you need to go to the hospital for an optometry examination, which is the gold standard for diagnosing refractive errors.

How many degrees of eyes.

1. The vision of the eyes is abnormal, perhaps myopia, pseudomyopia, farsightedness, astigmatism, and amblyopia are uncertain. It is recommended to go to the ophthalmology department of a regular hospital for a comprehensive eye examination to rule out other eye diseases, and then proceed after confirming refractive error**.

2. Pseudomyopia is corrected with drugs**, and true myopia or farsightedness can be corrected with glasses.

3. If the astigmatism exceeds 100 degrees, it can be corrected with glasses, and amblyopia should be trained to increase vision, preferably before the age of 9, and the source should not exceed 12 years old at most.

4. There is no correspondence between the visual acuity of the eye and the power, which are two concepts and cannot be calculated.

How can you protect your eyesight.

1. To protect eyesight, we first need to ensure the time for outdoor activities, and there should be more than two hours of outdoor activities every day, which can effectively reduce the incidence of myopia, so children should go to outdoor activities for more than two hours every day, which is under the light and cannot be carried out indoors.

2. The main way for adults to protect their eyesight is to develop good eye habits, and it is best to reduce the use of near eyes, especially near electronic devices.

3. If you use your eyes at close range for a long time, you can take a short break for about 5 minutes, and look at the distance to rest the eyes and lift the liquid.
