Monocular cues provide depth information when viewing a scene with one eye. Accommodation – This is an oculomotor cue for depth perception. When we try to focus on distant objects, the ciliary muscles relax allowing the eye lens to flatten, making it thinner.
The spaces of the eye are filled with the aqueous humour anteriorly, between the cornea and lens, and the vitreous body, a jelly-like substance, behind the lens, filling the entire posterior cavity. The aqueous humour is a clear watery fluid that is contained in two areas: the anterior chamber between the cornea and the iris, and the posterior ...
The refracting superposition eye has a gap between the lens and the rhabdom, and no side wall. Each lens takes light at an angle to its axis and reflects it to the same angle on the other side. The result is an image at half the radius of the eye, which is where the tips of the rhabdoms are.
A cataract is a cloudy area in the lens of the eye that leads to a decrease in vision of the eye. [1] [7] Cataracts often develop slowly and can affect one or both eyes. [1] ...
