Dear student

Light enters the eye through the cornea, pupil, and lens, and is then transmitted through the vitreous humor to the retina.


It fills the space between the lens and the retina (80% of the volume of the eyeball) which lines the back of the eye and helps to keep the retina in place by pressing it against the choroid.


The space that it fills is called the vitreous body.

 

Functions of aqueous humour:

Maintains the intraocular pressure and inflates the globe of the eye.
Provides nutrition (e.g. amino acids and glucose) for the avascular ocular tissues; posterior cornea, trabecular meshwork, lens, and anterior vitreous.
May serve to transport ascorbate in the anterior segment to act as an anti-oxidant agent.
Presence of immunoglobulins indicate a role in immune response to defend against pathogens.

Hope this clarifies your doubt.
