This is the text (if you need help).
Scientists can help older people to see better. They have a special red light. Looking at it for three minutes a day could help our eyes. A scientist said people should not buy any red light. They need a special one with the right wavelength. The scientists are looking for a partner to make the lights. They will cost around $20.
Researchers did tests on 24 people. They found that vision was worse in older people. The red light helped the older people to see better. Their sight got better by 22 per cent. A doctor said poorer eyesight will be a big problem. He said: "If you can't see clearly... you fall down and break bones."
Back to the red light lesson.
