Applying heat to the eyes every day cannot control myopia, but it can slightly relieve eye fatigue, dryness, and other discomforts. Myopia occurs when parallel rays of light enter the eye and focus in front of the retina through the eye's refractive system, failing to form a clear image on the retina.

If myopia is pseudomyopia, it might recover through rest, relaxation, and pupil dilation. However, if it progresses to true myopia, it becomes irreversible and incurable; vision can only be corrected and its progression controlled. Before the age of 18, myopia can be corrected with glasses or orthokeratology lenses. After turning 18, corrective surgery for myopia might be an option. It is advised that adolescents and children actively control the progression of myopia.

Can 600-degree acquired myopia be inherited?

A myopia of 600 degrees is considered high myopia, and it can be inherited by the next generation. Moreover, eyes with high myopia are prone to other complications at the back of the eye, such as retinal breaks, macular holes, and posterior staphyloma. Therefore, it is crucial to pay attention to high myopia and have regular check-ups. If both parents have high myopia, there is an 80% chance that their children will tend to be myopic. If one parent has high myopia, there is a 50% chance that their children will tend to be myopic. Even if neither parent is myopic, there is still about a 20% chance that their children will be myopic.

Does nearsightedness surgery require hospitalization?

Myopia surgery does not require hospitalization; it is completed on an outpatient basis. Before the surgery, routine blood tests, screenings for infectious diseases, and specialized eye examinations are conducted. If the pre-operative examinations are thorough and there are no contraindications for surgery, the procedure can be performed on an outpatient basis. After the surgery, patients can go home and must return to the surgical hospital the next day for a follow-up examination. Post-operative medication should be used as prescribed by the surgeon, and regular follow-up appointments should be scheduled.

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 difference between amblyopia and myopia.

Amblyopia refers to a condition where, through examination, the eyeball has no organic lesions, but the vision is poor. Even after correction, the vision remains significantly lower than normal, generally less than or equal to 0.8, without any organic lesions in the eyeball. In such cases, amblyopia can be considered. Myopia, on the other hand, refers to poor vision that can reach normal or better levels after correction. The difference between the two is that amblyopia cannot be fully corrected through adjustment, whereas myopia can be completely corrected. In terms of treatment, myopia can be corrected by wearing glasses or undergoing surgery, while amblyopia can only be managed by wearing glasses or undergoing specific amblyopia treatments.

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.
