#35 Human Eyes Are Made Of A Jelly Fluid Called Vitreous Humor
Vitreous humour is a translucent, colourless fluid that fills the gap between the retina and the lens of an eyeball. It holds 80 per cent space in the human eye and is made up of water and a mix of proteins, collagen, salt and sugars.
Any sort of problem with vitreous may detach the retina from the back of the eye, which would need surgery to be rectified. If not taken care of at an early stage, it can lead to permanent vision loss.
