im sure its when the lens either gets thicker or thinner to focus on near or far things
----------------------------------------------------------------
Accommodation is when the shape of the lens in the eye changes to make sure that a clear image is still being reflected onto the retina when you're looking at far of near objects.
When you look at a near object, a lot of light refraction is needed, so the ciliary muscles contract & the suspensory ligaments slacken so that the shape of the lens becomes fat & rounded.
When you look as a far object, not a much light refraction is needed, so the ciliary muscles relax & the suspensory ligaments tighten, allowing the lens to become long & thin.
In this way, you continue to see a clear image whether you're looking at something in the distance or something nearby & this is accommodation.
The ciliary muscle is responsible for eye accommodation for near and far vision. It accomplishes this task by changing the shape of the lens.

The ability of the eye to change its focal length is known as accommodation. This process involves the ciliary muscles adjusting the shape of the lens to focus on objects at varying distances. Accommodation allows us to see objects clearly whether they are close up or far away.
Accommodation is the term that means the lens of the eye can change shape. When it changes shape, the eye can focus on items far away or close.

Eye color is a physical change, not a chemical change. Eye color is determined by the amount and distribution of melanin in the iris, which is a physical characteristic that can change over time but does not involve any chemical reactions.
The lens of the eye, specifically the ciliary muscles surrounding it, can change its shape to adjust the amount of refraction. This process, known as accommodation, allows the eye to focus on objects at different distances by changing the curvature of the lens.
Franciscus Cornelis Donder has written: 'On the anomalies of accommodation and refraction of the eye' -- subject(s): Accommodation and refraction, Eye
Acc- Accommodation (eye).
During accommodation, the ciliary muscle contracts to change the shape of the lens, making it thicker to focus on close objects and thinner to focus on distant objects. The pupil constricts to reduce the amount of light entering the eye, enhancing focus. These changes help the eye to adjust and focus on objects at different distances.
This ability is called accommodation. It involves the lens of the eye changing its shape in order to focus on objects at different distances.
The ability of the eye to adjust its focal length is known as accommodation. Since a nearby object (small dobject) is typically focused at a further distance (large dimage), the eye accommodates by assuming a lens shape that has a shorter focal length
