The better you live, the better you see

This one should interest lots of you: A recent study about how healthy living improves a very specific element of vision, namely night vision.

In this paper from a UK research group, the researchers found that taking fish oil supplements led to an improvement in night vision, and as anyone who is getting older and likes to drive a lot, like me, of course, will likely confirm if they are honest, night vision does seem to get worse as you age, so this research may help me a lot, especially if it helps calm my wife down a bit more when we hit the road late for that long late-night drive home from Seattle.

Specifically, the researchers concluded that taking a supplement of docosahexanoic acid (DHA), a polyunsaturated fatty acid for 4 weeks, (DHA is found in fish oils, especially so in fatty fish like mackerel, tuna, halibut and salmon) improved ‘dark adaptation capabilities” in their test group of 19 people by about 25 % compared to before they had taken the supplements.

And no surprise, when they stopped taking the supplements, their vision returned to pre-supplement levels.

So want your driving partner to complain less when you drive at night?

Eat more fish.
