Atropine eye drops are used to dilate the pupil and relax the iris muscles in certain conditions, such as fundus examination or the treatment of iritis. They inhibit the action of the muscles that constrict the pupil, allowing the pupil to dilate temporarily to facilitate the examination or relieve spasms associated with inflammation. They are also sometimes used to treat lazy eye in children by reducing the work of the healthy eye and stimulating the weak eye to work. Atropine should be used according to the doctor's instructions and for a specific period to avoid side effects such as allergies or temporary blurred vision. It is recommended to avoid exposure to strong light during the period of the drop's effect, and to adhere to one dose each time and not repeat it without medical supervision. Therefore, atropine eye drops are one of the effective and important medications in the field of vision.
