This is a dilating drop using during your eye exam. This drop is used in conjunction with phenylephrine to make the pupil dilate to aid in visualizing the lens and retina.  Tropicamide is also a short-acting cycloplegia medicine and will make the vision blurry for a couple of hours. This drop is rarely prescribed outside the office, however, as longer acting cycloplegics like atropine and cyclopentolate are more effective in treating eye pain and inflammation.  Like all dilating drops, the bottle has a red-colored cap.
