The Eyes Have It

Sometimes, Mother Nature comes up with a great solution that takes human technology thousands of years to replicate. A new breed of artificial lens is controlled in much the same may as a human eye, by an artificial muscle that squeezes it into different configurations. The ability to focus a lens in this way, without direct control by electronics, will enable them to be deployed in situations where current solutions are no use – for instance, biosensors and medical imaging equipment.
