The initiative by Microsoft Research and the University of Washington, would be a big help to people with Type I diabetes patients, who must keep a check on their blood sugar on a daily basis by actually drawing blood several times a day.

The company had first issued the statement on August 19 after it was found that the lenses were linked to pain, red eye and blurred vision by wearers.

Tanya Vlach's dream is to make it web optimised, perhaps with its own app, so movement could be controlled externally. She has said that she would like sensors that respond to blinking, enabling the camera to take still photographs, zoom, focus and turn on and off.

In certain cases it could halt the short sight problem altogether. The special lens gently reshapes the front surface of the eye during sleep at night, a new study suggests. The finding suggests that orthokeratology (OK) lenses may help to reduce the growing incidence and severity of myopia throughout the world, and especially in Asia.

The leech made its way to the 66-year-old woman's eye while she was gardening in the backyard of her suburban Sydney home in March last year and accidentally flicked some moist soil and the blood-sucking organism into her left eye.
