The process of dark ______ is in play when you turn out all the lights in the room and can't see anything for a while, but eventually your eyes adjust to the new conditions.

Eye accommodation is when the eyes adjust their optical power to maintain an object in focus in the retina at varying distances. The process is achieved primarily by the lens changing its shape when focusing shifts from distant to near object and vice versa.
Accommodation works primarily by changes in the eye lens. Eyes adjust their lens to cause either more or less refraction of light so that the object is appropriately focussed on the retina. A high curvature creates a shorter focal length for near objects, while a flatter curvature is used to create a longer focal length for images at a further dist...
There are three main changes to the eyethat happen during accommodation. The changes affect the pupils, lens and overall eyes. The happen from convergence to pupillary constriction to lens accommodation
The accommodation reflex is importantbecause it enables you to focus clearly on objects that are up close when you are shifting from viewing objects far off. All the three eye changes must happen for you to see the near objects clearly. For instance, if the eye convergence does not happen correctly, you will have double vision. On the other hand, i...
With age, your eyes lose their ability to focus clearly and comfortably on up-close objects. The medical term for the condition is presbyopia, which usually takes place between the ages of 40 and 45 years. The main changes affect the lens and ciliary muscles. Age robs the lens of its internal elasticity, which affects its ability to curve and incre...
Accommodative dysfunctionrefers to a condition in which an adult or a child has difficulty with their eye-focusing system. The dysfunction results in blurred vision for up-close or distant objects, but often the problem is with near vision. Accommodative dysfunction also refers to eye-focussing problems unrelated to aging. There are three types of ...
