Miotics are a class of medications primarily used to treat conditions such as glaucoma by decreasing intraocular pressure. The mechanism through which miotics exert their therapeutic effects primarily involves the stimulation of contraction of the ciliary muscle. When miotics are administered, they activate the parasympathetic nervous system, leading to the contraction of the ciliary muscle.

This contraction results in two significant outcomes: first, it increases the aqueous humor outflow through the trabecular meshwork, which helps to lower intraocular pressure. Second, the contraction of the ciliary muscle causes a change in the shape of the lens, aiding in the accommodation process, which is the eye's ability to focus on near objects.

Understanding this mechanism is vital for recognizing how miotics contribute to managing eye conditions effectively. The other options do not accurately represent this process, as relaxation, inhibition, or enhancement of muscle elasticity do not align with how miotics function in relation to the ciliary muscle.
