The insides of the eyeball are really cool, but you can’t see them with just your own eyes!
Opticians and doctors use special a microscope called an opthalmoscope to look at these inner parts of the eye.
The biggest part of the eye sits behind the lens and is called the vitreous body. It accounts for two thirds of the eye’s volume and gives the eye its shape.
It’s filled with a clear, jelly-like material called the vitreous humor.
After light passes through the lens, it shines straight through the vitreous humor to the back of the eye which is where the retina is.
