Eye drops used to improve myopia generally refer to ciliary muscle paralyzing agents, including cyclopentanone eye drops, tropicamide eye drops, atropine eye drops, etc. The most definite effect should be low concentration of atropine eye drops, which generally refers to a concentration of 0.01% atropine eye drops. The principle of this type of medication for myopia refers to improving the spasm of the ciliary muscle by relaxing the ciliary muscle, thus relieving eye fatigue, by which pseudomyopia can be treated and the growth rate of true myopia can also be alleviated. Therefore, in the case of children, the onset of myopia can be prevented in this way; for true myopia that has already appeared, the growth of myopia can also be slowed down by using this type of medication.
