Not all myopia is hereditary, but high myopia does have a genetic component. The occurrence of myopia is mainly related to genetic and environmental factors. If there are children in the family with a history of high myopia, they should develop good eye habits from a young age, or undergo genetic testing for high myopia. If myopia occurs, it can be corrected by wearing glasses, or by refractive surgery after reaching adulthood.

Children's myopia lacks which trace elements?

The relationship between myopia in children and the lack of trace elements is not significant. Myopia is generally caused by several reasons: The first is hereditary factors, where one or both parents may have myopia. The second reason is poor eye habits in children, such as sitting too close to the desk while doing homework, or excessive use of the eyes, like watching TV or spending a long time on mobile phones, which can easily lead to myopia in children. Once a child develops myopia, the degree could increase by 50-100 degrees each year. Thus, if this is the case, it is necessary to conduct a timely dilated optometry for the child to confirm whether they can wear orthokeratology lenses. If the child is over eight years old and all conditions are suitable, orthokeratology lenses can be prescribed to control the progression of myopia.

The main cause of myopia formation

Myopia is primarily caused by the focusing system of the eyeball focusing parallel light rays in front of the retina when our eyes are in a relaxed adjustment state. The far point of a myopic eye is at a certain point in front of the eye. The occurrence of myopia is influenced by a combination of factors including genetics and environment, and the incidence is still being explored. Based on the refractive components, myopia can be classified into refractive myopia and axial myopia. According to the degree of myopia, it can be classified into mild myopia (below 300 degrees), moderate myopia (300 to 600 degrees), and high myopia (above 600 degrees). The clinical manifestations of myopia include blurry distance vision but good near vision, often with fluctuating distance vision where squinting is needed to see clearly at a distance.

Why can't true myopia be reversed?

True myopia is mainly characterized by the elongation of the eyeball, and the current medical level cannot solve the problem of eyeball elongation. Therefore, its nature cannot be changed, which means it cannot be reversed. Present treatment methods can only alleviate the symptoms of blurred vision when viewing distant objects in myopic patients, but cannot resolve the fundamental nature of myopia. Current treatment options include prescription glasses, orthokeratology lenses, contact lenses, and surgical treatments. Surgical options include corneal laser surgery and ICL (implantable collamer lens) surgery. After the onset of myopia, it is important to rest and use the eyes correctly to prevent further progression of the condition.

Can massage cure myopia in children?

If a child develops myopia, it generally cannot be cured through massage. Depending on the specific case of myopia, if it is pseudo-myopia, it can be cured by massage. However, if it is confirmed as myopia after a dilated eye examination, massage cannot cure it. Once a child has myopia, the degree of myopia can increase by 50-100 degrees per year, so it is essential to control it promptly. After a series of examinations, if the child is suitable for orthokeratology lenses, these lenses should be used as they are the best method to control myopia.

Can glaucoma patients undergo myopia surgery?

Glaucoma is a group of eye diseases characterized by atrophy of the optic nerve and defects in the visual field. Common symptoms include reduced vision, eye pain, and loss of visual field. In terms of treatment, it primarily involves the use of medications to control eye pressure or anti-glaucoma surgery to manage eye pressure, which helps delay the atrophy of the optic nerve and the loss of vision. However, since glaucoma has already caused damage to the optic nerve, it is generally not recommended to undergo myopia surgery, as it cannot improve vision.
