on 24 men and women aged between 28 and 72. They found that
used to process light deteriorated in the

, these people could see different colours
. The older people's sight got better by 22 per cent. A doctor said: "Populations are ageing
and this is going to be a major

you can't read or watch TV. You also tend to fall down and break
. Our lights are a
in this direction."
