Abstract
Dilatation of the pupil (mydriasis) is a core component of a comprehensive ophthalmic examination and is becoming part of the eye examination routine for optometrists in the United Kingdom. As many patients drive to attend their examinations, concerns have been raised regarding the effects of pupillary dilatation on driving and whether or not the visual standard for driving is met after dilatation. Therefore, we investigated the effect of mydriasis on the visual standard for driving a private vehicle in the United Kingdom. (Author/publisher)
