GCSE Biology · key term
The process in which the lens changes shape to focus light from objects at different distances onto the retina.
Used by AQA and OCR
Specification 4.5.2.3 · Paper 2
The change in lens shape that focuses light from near or distant objects onto the retina.
Revise: Accommodation for Near and Distant ObjectsThe cornea bends incoming light, while the lens changes shape to fine-tune the focus as you look between objects at different distances. This change in lens shape is called accommodation. A more curved lens bends, or refracts, light more strongly than a thinner lens.
Specification B3.1d · Paper 1 (Foundation), Paper 3 (Higher)
Revise: The eyeThe eye meets these different demands by changing the shape of its lens, a process called accommodation.

The adjustment of lens shape to focus light from objects at different distances on the retina.
Revise: The EyeThe lens changes shape to adjust the focus when you look at objects at different distances. This adjustment is called accommodation. Light from a distant point reaches the eye as nearly parallel rays.
Do not confuse accommodation, which changes lens shape, with the pupil reflex, which changes how much light enters the eye.
For accommodation, give the complete sequence: ciliary muscles → suspensory ligaments → lens shape → amount of refraction.
