â€¢ Solution uses Chlorine e6 (Ce6) insulin and saline to enable night vision
â€¢ A test subject was able to see in darkness 'for several hours'
â€¢ Ability wore off the following day, with 'no noticeable effects' after 20 days
â€¢ But researchers warn of a high risk of cellular toxicity as a result of the solution and said chemicals should be 'handled with cautionâ€™
A team of scientists claim it has found a way to inject peopleâ€™s eyes with â€˜night visionâ€™.
The research gave one volunteer the ability to see more than 164ft (50 meters) in almost total darkness for 'several hours'.
By injecting his eyes with a liquid solution, he could spot people running among trees in dark conditions 100 per cent of the time, while others who hadn't been treated with the drops were successful in only a third of cases.
