I can't see clearly up close when wearing myopia glasses

Nowadays, many children are found to be nearsighted when they just enter primary school. They cannot see the blackboard clearly, so they have to wear glasses. Otherwise, it will affect their studies. They have to wear glasses to see the blackboard clearly. However, sometimes you cannot see nearby objects clearly when wearing myopia glasses. This is abnormal. It may be because you have just worn the glasses and are not used to them yet. Wearing glasses will not affect your ability to see nearby objects.

1. Limit or offset near vision and improve eye sensitivity

1. Limit the time, distance, lighting, posture, etc. for students to read, watch TV, or use computers, and allow them to take a 5-10 minute break every 30 minutes or so. However, this method is not very reliable, because modern students cannot do without reading, using computers, etc., and the time they spend "looking close" is increasing. Therefore, it is preferred to use a farsighted lens to offset the nearsighted reflection and to virtualize reading and writing into a farsighted rest. The more students read and write, the better their eyes rest and the less likely they are to develop myopia.

2. Frequent eye movement or far-sighted-near-eye movement exercises (such as playing table tennis) can improve the sensitivity of eye muscle movement, but it is difficult for students to do it accurately or persist for a long time. Therefore, it is best to use a microcomputer-controlled sensitive mirror, which can be done very standardly and is easy to persist for a long time.

(II) Reasonable glasses

Preventing blurry eyes and lengthening of the eye axis caused by squinting: Blurred eyes will occur when looking at distant objects without glasses, which can induce chemical changes in the eye and cause lengthening of the eye axis; squinting can lengthen the eye axis, both of which can cause the occurrence and development of myopia.

Children with myopia of more than 50 degrees should wear glasses. If they do not wear glasses, they will not be able to see distant objects clearly or will squint, which may cause the eyeball to become longer or cause changes in myopia-related factors and accelerate the development of myopia.

For those below 250 degrees, they should only be worn when looking far away or at the blackboard. They do not need to be worn at ordinary times or when reading (because they can see clearly at close range but blurry at far distance). For those above 250 degrees, they should be worn all day (if they are worn sometimes and not worn sometimes, the frequent blurriness may cause the eye axis to lengthen and cause progression).

(III) Myopia control device: In principle, a myopia device of the second generation or above should be used to control two key aspects of myopia: near vision reflex and decreased eye sensitivity.

There are more than 30 kinds of myopia devices in China. However, according to the working principle, there are only four categories (i.e. four generations):

The first generation of myopia devices (using physical methods to indirectly act on the eyeball): such as various vibration, massage, magnetic therapy, electrotherapy devices, etc., which work by stimulating the acupuncture points around the eyes when the eyes are not looking. Since they have no direct effect on the "near vision" reflex, the long-term effect is almost 100% poor.

The second generation of myopia devices (using optical methods to offset near reflections): such as various farsighted lenses or defocused lenses, desktop farsighted lenses, etc., directly offset about 300 degrees of accommodative myopia through optical convex prisms when reading, writing, or using computers, and virtually transform "looking near" into "looking far" for rest. As long as you use it for a long time, the long-term effect will be better.

The third generation of myopia devices (those that use optical and physical methods to improve eye movement sensitivity): such as myopia sensitive mirror, eye sensitive resonant mirror, etc., prevent the occurrence and development of myopia by training adjustment sensitivity and visual field sensitivity. The effect will be better if used with the second generation myopia device.

The 4th generation of myopia devices (use optical physical methods to offset near reflection and improve eye sensitivity): such as myopia automatic control mirror (automatic farsighted mirror), desktop sensitivity memory farsighted mirror, etc. Automatic farsighted mirror can offset the near reflection through bifocal lenses and actively zoom far, reducing mixed myopia. Since myopia control is achieved during entertainment activities such as watching TV and using computers, it has an immediate effect. Therefore, it is very popular among students, parents and computer operators, and is currently one of the best instruments for controlling myopia.

4. Surgical treatment

Before the age of 18, posterior scleral reinforcement surgery can be performed to prevent the progression of high myopia. After the age of 18, if myopia no longer progresses, excimer laser surgery can be performed. To eliminate myopia.

The above content introduces us to the dangers of wearing myopic glasses. I believe that everyone now has a clearer understanding. We should develop good living habits and not wait until our eyes become myopic before seeking treatment. I hope that the above content will be helpful to everyone, and I also hope that all myopic teenagers can restore their normal vision as soon as possible.
