Eyes that speak
A recent breakthrough might eliminate the need for diabetics to repeatedly check their blood sugar by pricking their fingers.

The lens is being hailed as among recent times' biggest medical breakthroughs. In the coming years, we think we'll see more technology emerging, in which colour becomes a language we can both speak, and understand.
