Temporary paralysis of the ciliary muscle, preventing the lens from changing shape and eliminating the eye's ability to accommodate or focus on near objects. It is typically induced by using cycloplegic eye drops containing medications that temporarily paralyze the ciliary muscle. Cycloplegia is employed during comprehensive eye examinations to obtain an accurate measurement of refractive error by eliminating accommodation's influence.
