Eating plenty of salmon, sardines and mackerel may protect against sight loss, new research reveals.
A chemical in oily fish boosts the survival of cells that are critical to vision, protecting against age-related sight decline, a US study found.
Omega-3 oils 'precondition' cells in the eye to withstand 'stress', such as a loss of blood supply, according to researchers.
In laboratory tests, human eye cells exposed to constant light withstand damage if they are supplemented with such oils, the research adds.
Vision loss affects almost two million people in the UK. The leading cause is age-related macula degeneration (AMD) which has 600,000 sufferers.

In 2015, more than two million people in the UK were living with sight loss.
This affects one in five people over 75, particularly women.
At least 50 per cent of cases could be avoidable if the sufferer was fitted with the correct prescription glasses or underwent cataract surgery.
Older people with sight loss are almost three times as likely to suffer depression.
