It's a pretty common procedure worldwide; an ophthalmologist dilates the patient's pupils with eyedrops to be able to look inside them with a bright light and inspect for problems. Then afterwords the patient is sensitive to light for a few hours which impacts driving and everything else. Sunglasses work but the people most likely to see an eye doctor are those with glasses, and corrective sunglasses are pretty rare. Some eye doctors give out dark tinted face shield type things. The pupil-dilating drug is an anticholinergic like belladonna which has been known about for thousands of years (cf. name "belladonna" from the plant's use to dilate pupils as a cosmetic for "pretty ladies") (typically an anticholinergic like beladonna which has been known about for thousands of years)
