EYE EXPERIMENT

 CILIARY MUSCLE CONTRACT FOR NEAR VISION

CILIARY MUSCLE RELAX FOR DISTANT VISION

Mechanism:

• Normal Accommodation: The ciliary muscle contracts temporarily to allow the lens to thicken for near focus and then relaxes to flatten the lens for distant focus.
• Spasm of Accommodation: Persistent contraction of the ciliary muscle keeps the lens in a rounded state, reducing the eye's ability to relax for distant vision.

Cycloplegia

Cycloplegia refers to the paralysis of the ciliary muscle, resulting in the loss of accommodation. This prevents the lens from changing shape to focus on near objects, effectively rendering the eye focused only for distance vision.
