what is power of accommodation
Answers
The eye lens then becomes thicker. Consequently, the focal length of the eye lens decreases. This enables us to see nearby objects clearly.
The ability of the eye lens to adjust its focal length is called accommodation.
The Power of accommodation for a person with normal eyesight is around 4 dioptre (unit of lens power). Power of Accommodation of the eye is limited. The focal length cannot be altered after a certain limit.
Answer:
The human eye, with its various parts, plays a very important role in our lives. It helps us see. This may seem simple enough to just say it like that but a series of operations occur from the point of light rays entering our eyes till we perceive the image of whatever we are seeing. One of these processes is the Power of Accommodation of the eye.
Accommodation of the Eye
The process by which certain muscles (called ciliary muscles) function, to change the focal length of the eyes so that the image is clearly formed on the retina is called the accommodation of the eye. This will vary for near and distant objects and also for objects moving away or towards the eye. By adjusting the focal length, the eye is actually changing its lens power as well isn’t it? This is called the accommodating power of the eye. Literally. the eye’s power to change its power.
