Anteriorly there aquaeus humor and vitreous posteriorly there. The lens capsule is a semi-permeable membrane which will allow entry of water and electrolytes. Lens held in temaptnya by a ligament known as zonula (zonula zinnii) to siliare body. Eyepiece serves to refract light
Is a clear fluid that fills the anterior and posterior eye camera. Intraocular pressure is determined by the rate of formation aquaeus humor
Is a clear gelatin body and avascular which form two-thirds of the volume and weight of the eye. Vitreous fills the space bounded by the lens, retina, and optic disc
The third tier of the eyeball is the retina which is the deepest and have tabled as many as 10 layers layer which is layered membrane neurosensoris that will change the light into the optical nerve stimulation and transmitted to the brain.
