"Post-mydriatic": Mydriasis is pupillary dilation and without pupillary constriction, bright lights can dazzle you or even cause a temporary bleaching of the retina. Pharmacologic dilation for diagnostic testing and examination can last 3 or more hours, depending on the drops used and the color of your eyes, with lighter colors lasting longer. The near vision is typically more impaired than the distance.
