Atropine, a non-selective M-receptor antagonist, is a drug that is recognized worldwide as being effective in slowing the progression of myopia. 0.01% Atropine is usually effective in suppressing the increase in refraction and eye axis. The higher the concentration of atropine, the better the control of myopia, but the more pronounced the adverse effects of the drug. 0.01% atropine can effectively inhibit the increase of refraction and eye axis, and has relatively few adverse effects. Atropine 0.5%-1% can also inhibit the growth of the eye axis and the further development of myopia, but may cause photophobia, pupil dilation, allergic conjunctivitis, reduced regulation and other Long-term pupil dilation may even lead to complications such as cataracts and retinal photodamage. For patients with myopia, it is recommended that they go to a hospital to have their vision tested and then choose to control their myopia with glasses, medication, surgery, etc. depending on the cause of their myopia. Do not use medication privately without permission, as this may cause eye discomfort and worsen symptoms.
