New research from China has found that lutein — found in the vegetable kale — can help improve your night vision.
Lutein is found in the eye and, if low, a person’s vision is impaired.
The study found that those who had consumed daily lutein supplements over a year’s time actually improved their sensitivity to glare, overall vision, and contrast ability.
A look at the right way to add the supplement to your diet (via Men’s Health):
The 20 milligrams (mg) of lutein that people consumed every day is about the same as 1 cup of cooked kale (about 4 cups raw)—not exactly a small amount to consume daily. But a diet rich in a variety of fruits and vegetables will help you consume optimal levels of the nutrient, suggests a study from the University of Texas.
However, if you’re looking to sharpen your vision, you may need to take a supplement to really see the effects.
Potential causes that lead to low lutein include poor diet, smoking and exposure to UV light.
