The lens’s biconvexity increases as tension is released, allowing it to focus more precisely on closer objects. The ciliary muscles in the eye become weak, causing the lens focusing system to fail. WebAttached to these choroids are muscles called ciliary muscles that stretch the choroids out when they contract.
