A little nearsighted. Do you want to wear glasses?

Abstract: when we are short-sighted, in the relaxed state of adjustment, when the parallel light enters the eye, it will focus in front of the retina, so a clear image can not be formed on the retina. It needs to be corrected with concave lens so that the light can focus on the retina., When you have severe myopia, once you don’t wear glasses, it’s like the world is mosaic. Needless to say, most people will wear glasses themselves., But the problem is, if it’s only 100-200 degrees myopia and you can see things without glasses, is it OK to wear glasses or not?, Let’s first look at how our eyes see things. When our eyes are normal, that is, there is no myopia, hyperopia and astigmatism, parallel light enters our eyes, refracts through cornea and crystals, and finally focuses on the retina to form a clear image. The retina then transmits the information to the brain through nerves, The brain center processes the images obtained by both eyes, and finally we can see the object clearly., When we are nearsighted, when the adjustment is relaxed, the parallel light enters the eye and will focus in front of the retina, so a clear image cannot be formed on the retina.

when you have severe myopia, once you don’t wear glasses, it’s like the world is mosaic, so needless to say, most people will wear glasses themselves.

but the problem is that if you are only 100-200 degrees myopia, you can see things without glasses. Is it OK to wear glasses or not?

let’s first look at how the eyes see things.

when our eyes are in normal condition, that is, there is no myopia, hyperopia and astigmatism, parallel light enters our eyes, refracts through cornea and crystals, and finally focuses on the retina to form a clear image, which then transmits the information to the brain through nerves, The brain center processes the images obtained by both eyes, and finally we can see the object clearly.

when we are nearsighted, when the adjustment is relaxed, the parallel light enters the eye and will focus in front of the retina, so a clear image cannot be formed on the retina. A concave lens is needed to correct so that light can be focused on the retina. The reason why

and

are in a state of adjustment and relaxation is that our eyes have the ability of adjustment, especially in children. If it is not in the state of adjustment and relaxation, the degree found is inaccurate.

this is why we need to dilate the pupils before optometry when checking the degree of children clinically, because only after dilation, the adjustment of the eyes will be relaxed and the accurate degree can be found.

for children with low myopia, do you want to wear glasses?

and

for children, because the eyeball is still developing, once myopia occurs, the degree will continue to progress. Many parents will feel that they can’t take off their glasses. They think we should not wear glasses at all.

in fact, this is wrong, because the progress of degree is related to the eyes themselves and eye habits. Wearing glasses correctly can not only help you see clearly, but also slow the development of myopia. This has been confirmed by many studies.

in addition, if one eye sees things clearly and the other eye is blurred, it may affect the brain’s binocular fusion function for a long time, which may not only inhibit the eyes with poor vision from seeing things, thus becoming amblyopia, but also affect the stereo vision of both eyes.

if the images obtained on the retinas of both eyes are blurred, it will not only affect children’s learning and life, but also affect the visual development of the brain and may form amblyopia.

therefore, for children, if the refractive myopia degree has exceeded 100 degrees after mydriasis, it is recommended to wear glasses in time.

and

in adults, does it affect low myopia without glasses?

some people may feel that wearing glasses is not good-looking, or they feel uncomfortable when wearing glasses. They haven’t worn glasses much for various reasons, and they also feel that they can see things. There will even be a feeling that my eyesight seems to be getting better without glasses for a period of time.

this is because many people confuse the concepts of vision and power. Our normal vision to see things without glasses is called naked vision, which is affected by many factors. The diopter found by optometry can more accurately reflect the refractive status of the eye. The vision after wearing glasses, that is, corrected vision, really reflects the ability of your retina to see things.

you may find that, for example, two people with corrected vision of 1.0 and optometry of 300 degrees are short-sighted. If one person does not wear glasses and the other person wears glasses all the time, their naked eye vision is likely to be different, and usually the person without glasses is better.

this is because when you don’t wear glasses for a long time, your retina has always been blurred, and your brain center may adapt to this blurred image through certain mechanisms. It’s like that we sometimes meet acquaintances on the road, but we don’t really see their appearance, but just a general outline. Of course, if

and

are too vague, they can’t be distinguished. Therefore, this ability still requires the degree of ambiguity. That’s why when the degree is deep, it can’t be seen, but only a little degreeI also feel that not wearing glasses has little impact on my life.

but in fact, the eyes always tend to get the clearest imaging. Therefore, when you feel as if there is nothing, in fact, when you are looking, your eyes are already using adjustment, which may lead to visual fatigue after a long time.

and

can’t always see the world clearly. In fact, they may miss some important details in life. It is suggested that people in need should wear glasses as much as possible.
