Now stay with me here……the future of computers may well be in contact lenses?! Yes, that picture above that you see is exactly what it seems. Okay, I’ll explain.
A team from Washington University recently completed trials on a new generation of contact lenses that would project your emails directly onto your eyeballs. Circuits in the lenses are made from layers of metal only a few nanometres thick and feature light-emitting diodes measuring 1/3 of a millimeter across.
The next step is to incorporate hundreds of pixels into the lens. The team believes they can eventually produce complex holographic images and price comparison information just by looking at a specific product. Speculation that we’ll be able to stream web content using contact lenses is also on the table.
There are some major challenges however. One, they have to make the contacts as comfortable as normal ones currently on the market. That pretty much means they have to feel like nothing is in your eye. More challenges include powering these contacts. They are currently without a viable power source and the current prototype only works if it’s within centimeters of a wireless battery. Lastly, there may be uncertain long-term effects of wearing a lens made of electrical circuits that is touching the surface of your eye. Imagine wearing these contacts in the scorching heat?
Very interesting ambitions. I’m still kind of speechless to be quite honest. As a person that wears contact lenses all day, everday, I really haven’t the slightest interest at this point.
