There are two types of eye drops: one stimulates muscle contraction, which increases pupil (like phenylephrine); the other relaxes the muscles responsible for contracting pupil as well as relaxes the muscle responsible for the focusing action of crystalline (like ciclopentolathus and atropine). These two types of medicine are frequently used together.
