If we have two eyes, then why is our vision so limited? Why do we have so little depth perception? Why don't our two eyes offer us two different views of the world? Why don't they allow us to look behind and in front at the same time, or sideways in both directions?
Artists Cleary Connolly and Neil McKenzie have spent several years developing an extraordinary series of helmets, that help us to explore these and other mysteries of visual perception.
