Clinical ciliary muscle paralyzing agents, which are mainly dilating drugs, not only paralyze the ciliary muscle, but also dilate the pupil. Dilated pupils may be followed by photophobia and even blurred vision in the near future. The duration of side effects may vary depending on the duration of the ciliary muscle paralyzing agent. Fast ciliary paralytics may have side effects for 1-2 days, while slow ciliary paralytics, such as atropine, may have effects for up to 3 weeks. Atropine may cause atropinization, such as facial flushing or sweating, after excessive use, but these effects will fade as the drug wears off and will not cause much harm. If there is photophobia need to wear a pair of sunglasses, if it is not clear to see near, you can wear glasses similar to presbyopic glasses, you can also adjust and correct.
