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

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