What is inside a human eyeball?
Most of the eye is filled with a clear gel called the vitreous. Light projects through your pupil and lens to the back of the eye. The inside lining of the eye is covered by special light-sensing cells that are collectively called the retina. It converts light into electrical impulses.

What is white part of eye called?
The sclera, or white of the eye, is strong tissue that wraps around the eyeball. It helps maintain your eyeball’s shape and protects it from injury.

It might look scary, but it’s usually harmless. Your conjunctiva, the clear membrane that covers your eye, has a lot of tiny blood vessels. When blood gets trapped beneath this layer, it’s called subconjunctival.
Why do eyes turn blue?
There are lots of reasons someone can have blue “whites”. Anything that results in a thinning of the sclera could cause it. For example, some medications, like steroids, can produce blue sclera. Not having enough iron in your blood (anemia) and aging have also been shown to give a blue tint to the whites of the eye.
What are the GREY spots in my eyes?
Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes becomes more liquid. Microscopic fibers within the vitreous tend to clump and can cast tiny shadows on your retina. The shadows you see are called floaters.
Why is there a red thing in my eye?
A subconjunctival hemorrhage is a red spot on your eye caused by a broken blood vessel. It might look scary, but it’s usually harmless. Your conjunctiva, the clear membrane that covers your eye, has a lot of tiny blood vessels. When blood gets trapped beneath this layer, it’s called subconjunctival.

Can an eyeball fall out?
Not all popped eyeballs come from head trauma. A few people can luxate their globes on purpose, and certain others get “spontaneous globe luxation” when their eyelids are pushed in the right way. Someone with shallow eye sockets or floppy eyelid syndrome, for example, might pop his eyeballs during a regular eye exam.
