This is the trade name for the dilating drop tropicamide. This is a short-acting dilating drop used during an eye exam to dilate the pupil.  This drop also has cycloplegia effects which means that it will cause a fair amount of blurriness (especially with reading).  It is the shortest acting dilator available, but even so, the dilation/blur can last anywhere from 3-8 hours.
