為什麼要控制近視?

To avoid progression to higher degree of myopia

To avoid structural change of eyeball and ocular complications associated with high myopia

To avoid irreversible visual loss

Q:   Why is it important to correct vision in childhood
A: Myopia in children is mainly caused by elongation of the eyeball (elongation of the ocular axis). It is easy to become myopia if you become habituated to looking at things up close, and once the axial length of the eye is elongated, it will not return. For this reason, it is important to suppress the lengthening of the ocular axis in order to control the progression of myopia.

Severe myopia can also lead to irreversible vision loss, macular degeneration, retinal detachment, and glaucoma.

Also, myopia will get worse if eyesight is under-correction, monovision or over-correction
