Eye fatigue can exacerbate myopia, and it is an important factor in worsening nearsightedness. When the eyes look into the distance, they are in a completely relaxed state, which does not cause or worsen myopia. Myopia occurs due to near-distance eye activities. Prolonged close-distance eye activities and working too closely can lead to chronic fatigue in the external eye muscles. When this happens, the eye axis is stretched and, over time, cannot fully return to its original state, resulting in the onset or worsening of myopia. Therefore, during daily eye use, it is essential to avoid excessive duration and too close distances to prevent fatigue and thus avoid worsening myopia.

What should we do if a child has severe myopia of 800 degrees?

Myopia can be divided into pseudomyopia and true myopia, with true myopia further categorized into low, moderate, and high degrees. Clinically, myopia exceeding 600 degrees is usually referred to as high myopia. High myopia not only causes blurred vision in children but can also lead to various eye diseases, such as retinal detachment. Thus, it is very serious. Moreover, once children develop high myopia, their vision might continue to deteriorate even into adulthood. Therefore, parents must pay significant attention. During childhood, methods such as wearing glasses can be used to control the progression of myopia. If the child has reached adulthood and their eyesight has not continued to worsen over two years, considering treatment options like surgery might be possible, though currently, it is incurable.

Will nearsightedness be inherited?

Myopia has a certain hereditary aspect, but it is mainly caused by improper use of the eyes. Myopia is characterized by clear near vision and blurred distant vision, primarily due to changes in the eye's axial length. After the onset of myopia, it is crucial to properly dilate the pupils and conduct an optometric examination to rule out false myopia and amblyopia. Currently, the main treatments for myopia are still corrective glasses or orthokeratology lenses. Surgical treatment can also be considered for individuals aged 20 to 45. Once myopia develops, proper eye usage should be practiced, reducing close-range activities to avoid eye strain, and regular follow-ups are advised.

Can people with high myopia and floaters undergo myopia surgery?

Patients with high myopia who experience floaters can also undergo myopia correction surgery to eliminate nearsightedness. However, symptoms of floaters will not improve after the surgery. The commonly used myopia correction surgeries include laser surgery and the implantation of a posterior chamber intraocular lens for aphakic eyes. Patients need to visit the ophthalmology department of a hospital for optometry, corneal topography, and A-scan ultrasound examinations. The type of surgery is then determined based on the condition of the eyes. Floaters are caused by the clouding of the vitreous body within the eye due to aging. They can be treated with oral medications to promote absorption. For example, currently, lecithin complex iodine tablets can be taken, but the absorption is slow, requiring patients to adhere to regular treatment. (Please follow the doctor's advice when taking medication.)

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.
