Explain accommodation in the human eye for distant and near vision.

You're on a roll — Accommodation is the process by which the eye changes its optical power to maintain a clear image or focus on an object as its distance varies. This is achieved by changing the shape of the lens. For Distant Vision (objects further than 6 m): • The ciliary muscles relax. • The suspensory ligaments tighten (become taut). • The tension on the lens increases. • The lens becomes less convex (flatter). • Light rays are refracted less. • Light rays are focused onto the retina. For Near Vision (objects closer than 6 m): • The ciliary muscles contract. • The suspensory ligaments slacken. • The tension on the lens decreases. • The lens becomes more convex (more rounded). • Light rays are refracted more. • Light rays are focused onto the retina.
