Night vision study

FISH oil supplements can significantly improve ‘night vision’, according to a new study.

Researchers from Loughborough University wanted to know whether docosahexanoic acid (DHA), a polyunsaturated fatty acid found in fish oils, improved ‘dark adaptation capabilities’ – the process the eyes go through when adjusting to new light levels.

Researchers found that, on average, people were able to identify images that were 25% fainter the second time around – after a course of fish oil.

Six weeks after finishing the supplements, their ‘night vision’ returned to original levels.
