Bionic eye

In an experiment involving rats, researchers at the Stanford University, US, have successfully implanted a 3-millimetre-wide chip behind their retinas. The implants will make up for their retinal dysfunctions. This 'bionic eye' will in future help patients who will wear goggles mounted with a small video camera. Light will enter the camera and send the image to a wireless computer for processing and transmitting that into an infrared image on the goggles' LED screen. The goggles will reflect an infrared image on the retinal chip and stimulate its photodiodes which will mimic the retinal cells by converting light into electrical signals. The signals, transmitted by cells in the inner retina via nerve pulses to the brain, will one day help blind people ' suffering from diseases like retinitis pigmentosa and macular degeneration ' see again.

Snoopers' envy

If you really need to keep those wandering eyes of your nosy colleagues away from your monitor, the 3M company's privacy filters can be of immense help. With this filter over the monitor, anyone trying to sno-op will see a black screen; only the person working directly in front of the machine will see what's on the screen. Besides making things difficult for others, the filter reduces glare and improves clarity.
