Scientists believe they have found help older people suffering poor eyesight. The solution is shining a special red light the eyes for three minutes. Doctors say a three-minute daily dose the special red light for two weeks could help improve age-related vision problems. However, they say not any red light will help improve eyesight. The co-author a study into the effects red light and vision older people explained why. Professor Glen Jeffery said: "I strongly suggest that people do not just go and buy a red light the web. They have to produce the right wavelength and be reliable. We are looking a commercial partner to do this and to price them under around $20 to $25."

The study was carried by a team from University College London. Researchers conducted tests 24 men and women aged 28 and 72. They said some cells that help us process light had deteriorated the older people. Doctors say their red light improved the ability these people to detect different colours, particularly blue. The vision these older people improved as much as 22 per cent. Doctor Jeffrey said: "Populations are ageing rapidly and this is going to be a major issue the future. We need to gear for this." He added: "If you can't see clearly you can't read or watch TV. You also tend to fall down and break bones. Our lights are a step this direction."
