Eye flickers key for fine detail

Tiny, involuntary movements made by our eyes when we focus on something could be more useful than we might think, scientists have found.
We may not be aware that our eyes are making these movements, but without them our vision fades.

And scientists have now found that they could also be important in helping us to see very fine details.

The research, carried out by scientists at Boston University, was published in the journal Nature.
