The Ladies will be so happy about this, but remember, always be careful
The revolutionary lenses would allow individuals to zoom in and out, also offering hope to thousands of elderly people suffering from vision loss.

The prototype lenses, presented at the American Association for the Advancement of Science’s yesterday in San Jose, California, contain tiny aluminium telescopes that would interact with a pair of specially designed glasses to allow you to toggle between normal and ‘zoomed in’ viewing.

The operating instructions tell users to wink the right eye to zoom and the left to zoom out.

The lenses, which were first developed with the US Defence Advance Research Projects Agency as super-thin cameras for aerial drones, have been retooled as a possible solution for those with age-related macular degeneration.

Macular degeneration is when the light receptors on the inner surface of the eye are lost, resulting in blurred central vision. This can make performing normal tasks – such as reading – near impossible.

Eric Tremblay, from the Swiss Federal Institute of Technology in Lausanne, said: “We think these lenses hold a lot of promise for low vision and age-related macular degeneration.

“At this point, it is still research but we are very hopeful it will eventually become a real option for people with age-related macular degeneration,” Mr Tremblay told the Daily Mail.

However, before the lenses can be rolled out scientists need to create a lighter, more ‘breathable’, version.

The rigid prototypes, which still allow light through the centre of the lenses, are bigger and thicker than traditional lenses but surrounded by mirrors.

It is these mirrors that provide the ‘superhero’ elements of the contact lenses. By bouncing the light around the view – as seen by the wearer – is magnified.
