The term accommodation refers to the process by which a person's vision is adjusted to focus on objects at varying distances. This involves the muscles in the eye contracting or relaxing to change the shape of the lens, allowing light rays from distant or nearby objects to converge onto the retina correctly. The ability to make these accommodation changes is essential for clear and comfortable vision, particularly when switching between looking at something up close (such as reading) and something far away (like watching a television screen).
