Dilated Pupils
When mydriasis is a side effect of medication or recreational drugs, pupils usually return to their normal size within hours. When the pupils are dilated, the eyes become more sensitive to light. This can lead to blurry vision, as well as, in some cases, a general feeling of constriction around the forehead and eyes. Eye specialists called ophthalmologists and optometrists may use special eye drops called mydriatics to dilate the pupils during eye exams. A condition called benign episodic pupillary mydriasis happens when an otherwise healthy individual with a history of headaches suddenly develops dilated pupils.
In bright light, your pupils constrict (get smaller) to prevent too much light from entering your eyes. In dim lighting, your pupils dilate (get larger) to allow more light in.

Substance abuse is a serious issue that affects millions of Americans.

These often increase intracranial pressure, which can put pressure on and affect the eye system.

The presence of a dilated pupil on only one side suggests that a large mass or lesion may be present. Opioid use disorder can lead to serious health consequences, including eye damage, but recovery is possible.

This is a sign of vision problems in the eye that don’t elicit pupil constriction. Diagnosis of the cause of unequal pupils involves a comprehensive physical examination, including an eye examination and a neurological examination. Any injury, disease, or chemical that interferes with one or more of these functions can lead to anisocoria. This can be a harmless physical feature or a sign of an eye or brain problem.
