OCULAR ACCOMMODATION Meaning and
Definition
-
Ocular accommodation refers to the ability of the eyes to adjust and focus at various distances, allowing for clear vision. It is a natural process that occurs as the eyes change the shape of their lenses to alter the focus of incoming light.
The process of ocular accommodation begins when the eye focuses on an object at a specific distance. In order to bring the object into clear focus, the muscles surrounding the lens contract, causing the lens to change its shape. This change in shape adjusts the focal point of light so that it falls directly on the retina, resulting in a sharp and clear image.
Ocular accommodation is essential for the eyes to maintain clear vision at different distances. For instance, when looking at nearby objects, the eye's lens becomes thicker and rounder, which increases its refractive power. This adjustment is known as accommodation for near vision. Conversely, when focusing on distant objects, the lens becomes thinner and flatter, reducing its refractive power for a clearer view.
The ability of the eyes to accommodate gradually decreases with age, leading to a condition called presbyopia, where the eye has difficulty focusing on nearby objects. This condition is commonly experienced by individuals as they enter their 40s or 50s.
In summary, ocular accommodation is the process by which the eyes adjust the shape of their lenses to focus incoming light and provide clear vision at various distances. It is a natural ability that allows individuals to see objects both up close and at a distance.
