A team of physicists at ETH Zurich has created a tiny metalens that can half the wavelength of incident light.
They have achieved this using a special metal-oxide lens material called lithium niobate and through nanoscale pattern, stamped into the material.
Such metalenses could be used as a security feature on banknotes or in the fabrication of ultra-thin elements for cameras.
A contact lens would gain a lot of situational awareness and mobility.
Seeing what happen to my wife eyes (that use contact lens) when even the smallest dirt gets in her eyes, I would say that in a open combat zone the googles seems to be way more effective.
Maybe the best compromise would something like a simple sunglasses, the same as the glasses that filter the blue light.
