extend the order-of-magnitude calculations a little. Probably complete rubbish, but what can you expect from a physicist completely clueless about biology. |

* '''Retina''' - the tissue that supports the rods and cones. | * '''Retina''' - the tissue that supports the rods and cones. | ||
* '''Choroid''' - the structure behind the sclera. It can change thickness (on a timescale of days) to make small adjustments to the [[axial length]] | |||
* '''Vitreous humor''' is the clear gel filling the majority of the eyeball. It is where true [[floaters]] live. This gel is important for helping the eye hold its shape and maintain the correct pressures inside the eye even when air pressure changes. In adults, the gel has a complex structure, with different thicknesses in different parts. | * '''Vitreous humor''' is the clear gel filling the majority of the eyeball.

* '''Vitreous detachment''' is attached to the outer wall of the eye in multiple locations, but can become separated. When separated from the retina it does not support the retina fully, and puts you at higher risk for [[retinal detachment]]. It can also leave behind a large [[floater]] that impairs vision. | * '''Vitreous detachment''' is attached to the outer wall of the eye in multiple locations, but can become separated.
