Omega-3 fish oils help protect our sight as we get older

Fatty acids from fish protect us against inflammation and heart disease – and they can also help keep our eyesight sharp as we get older, new research has discovered.

DHA, an omega-3 fatty acid, stops the build-up of a toxic molecule at the back of the eye, which causes vision loss when we are old.

The ‘black box’ warnings, which are issued by America’s drug regulator, the Food and Drug Administration (FDA), were ignored by the doctors who were visited less frequently by the salesmen, and so carried on prescribing them.  Only the doctors who had frequent visits were aware of the drugs’ dangers, and had moved on to safer alternatives.

The research team from the University of Alberta are now investigating the impact of DHA on people with age-related macular degeneration (AMD), a common cause of vision loss.
