Explanation: 

Detailed explanation-1: -Dilated pupils (mydriasis) are when the black center of your eyes are larger than normal. The condition may be caused by dilating eye drops from an eye exam, the side effects from a drug/medication or traumatic injury.

Detailed explanation-2: -Students often have trouble remembering the difference between mydriasis and miosis. Both words describe pupillary dilation, but which is which? Mydriasis refers to a dilated pupil or a wider pupil. Miosis refers to a constricted pupil or a narrower pupil.

Detailed explanation-3: -Pupils tend to become bigger (dilate) in low-light situations. This allows more light into the eyes, making it easier to see. When there’s a lot of bright light, your pupils will become smaller (constrict).
