We’ve all heard the old wives’ tale that eating carrots can help us see in the dark. But eating your way to better eyesight isn’t only about munching more root veg. A raft of recent research has found several other key vitamins and minerals are just as essential. 
Research shows our intakes of oily fish, the main source of Omega-3 fats, fall short of recommended guidelines while leafy green vegetables are under-consumed, meaning nutrients such as lutein are lacking from diets. We all need to find ways to include more of these foods in our diets or consider supplements to improve levels. These seven superfoods will help keep your peepers healthy:

WHY? This – along with other leafy greens such as broccoli and kale – is packed with zeaxanthin and lutein, which lower the risk of developing macular degeneration and cataracts. Lutein protects the eye by forming pigments in the macula that filter out harmful blue light waves, which can damage the eye.
