Eating a lot of oily fish may protect against age-related vision loss. This is stated in a new study published in the journal Cellular and Molecular Neurobiology..

In oily fish (trout, sardines, herring, etc.). ) contains omega-3 fatty acids - substances that increase the survival of cells critical for normal vision. Omega-3 fatty acids help cells in the human eye cope more effectively with stress, such as that caused by a lack of blood supply, scientists say..

In laboratory tests, human eye cells were constantly exposed to light to see how well they coped with its influence.. When using omega-3 fatty acids, the cells were much better able to withstand this test..

The retina is a thin layer of tissue at the back of the eye..

It converts light into signals that are sent to the brain, where they are processed into images.. Damage to the retina leads to degeneration of the macula, which is responsible for what we see directly in front of us, that is, for central vision.. This type of vision is critical for reading, writing and color discrimination..

Although oily fish also contains omega-6 acids, which cause inflammation and therefore pose a threat to vision, their action is completely suppressed by omega-3 acids, scientists say..
