My OperaIntegrated display with contact lenses

A select group of researchers have tested a new screen that can be embedded in a contact lens and works wirelessly using a separate power source. Despite the fantastic possibilities of this device, has a long way to go before it ends in a close eye on you.
Integrated display with contact lenses
For now, the screen is not only a "rudimentary proof of concept." In its current form, the electronic system for the device can handle only a single pixel.
The researchers aim to improve this limitation, with a little more time and more research. "Our next goal is the incorporation of a default text in the contact lens." Said lead researcher Dr. Parvis.
The research states that wireless power source may be about a meter away from the device, in terms of visibility.
More interesting would be a power source that could also be installed on the user, but the feasible distance decreases drastically to about two inches.
The team determined using this test using rabbits and embedding wireless power sources in their heads.
With this experimental sample, Vision Without Glasses the team has overcome a series of challenges. One problem solved was that was trying to get the eye could see something mounted on its surface. Usually, the eyes need at least a few inches of focus.
The integration of circuits on something as delicate as a contact lens is another matter. The electronics are made of inorganic materials, requires high temperatures and contain toxic chemicals that make them difficult to integrate. The team found a way to produce extremely thin circuit embedded in the contact lens itself.
The chips are on the contact lens is built on a transparent sapphire substrate nanometers thick. The image itself is produced by a small LED that is a fraction of a millimeter. Researchers are working to add more and more LED chips for multi-pixel version based on micro-Fresnel lens.
Among the possible uses cited, as the HUD-like functions such as monitoring the levels of blood sugar in people with diabetes or GPS based on the instructions for the drivers are pretty ingenious ideas.
However, people involved with the project admitted, "to have the lens with high resolution full-color, may be in years to come."
