What happens if ciliary muscles contract too much?
Normal accommodation allows the eye to “accommodate” for near-vision. However, in a state of perpetual contraction, the ciliary muscle cannot relax when viewing distant objects. This causes vision to blur when attempting to view objects from a distance. This may cause pseudomyopia or latent hyperopia.
What is the function of the ciliary body?
