Briefly explain how monocular vision works.

This is what an eye looks like. In a healthy one, light comes through the ‘cornea’ at the front and is focussed by the ‘lens’ onto the back of your eye. There’s a layer of special nerve cells that detect light and colour and that’s the ‘retina’. From there, the brain works out what we are seeing. But what some people see isn’t always clear.
