What are the dangers of atropine eye drops?

The hazards of atropine eye drops are dilated pupils, effects on vision, and allergic reactions. Atropine drops, usually referred to as 0.01% atropine drops, are a more commonly used ciliary muscle paralysing agent with regulatory paralysis, dilating pupils, and can be used to dilate pupils prior to refractive examinations, as well as for the treatment of refractive errors in children.
Atropine itself is an M-blocker and can cause toxicity in excess. 0.01% Atropine is a low concentration, but it acts directly on the eye mucosa and can also cause side effects. For example, after using atropine to dilate the pupil, some patients are unable to recover at first and may suffer from short-term blurred vision and loss of vision. Some patients suffer from allergic reactions caused by atropine, resulting in symptoms such as excessive sweating, congestion in the eyes, dry mouth and dry throat.
