Foods to Improve Eyesight | Improve Eyesight with Healthy Food
If you want eyesight better than 20/20, or want to prevent eyesight deterioration, it’s good to know why your vision depends on nutrients to see clearly. Choose right foods to improve eyesight.
Much of this information comes from the research. And the amazing thing is that this research started long before many people with eyesight deterioration were even born.
As early as 1945 scientists found that the macula of the eye had yellow carotenoid pigments in it. Nutritional research lagged behind though and no one knew that these yellow pigments were found in foods until many years later.
In 1958, there was evidence that vitamins helped improve macular degeneration. One of the first vitamins tested was vitamin E. To perform this research, the scientists decided on what would define improvement for macular degeneration. Their criteria was that improvement meant there was a reduction of distorted vision. In other words, if you looked at two separate lines on a paper close to each other and saw them as one line or saw them as wavy, then this is considered distortion.
What the researchers found was that two thirds of the participants improved the distortion in their vision, thereby improving their macular degeneration. Two thirds is pretty significant! You don’t find very many studies these days that show that something helps a condition in two-thirds of the study participants. Yet, nutrition worked.You can find foods to improve eyesight.
Nutritional Research On Eyesight Sees 20/20
Thirty years later, the National Health & Nutrition Examination Survey found that by eating a diet rich in beta carotene, people over 45 years old were at lower risk of developing macular degeneration than those who didn’t have a diet rich in beta carotene.You can choose foods to improve eyesight without glasses.
By 1993 the research was quantifiable by doctors at Johns Hopkins University and Harvard University. Those who ate a diet rich in carotenoids were 43% less at risk to develop macular degeneration. By eating spinach or collard greens five or six times a week reduced their risk of developing macular degeneration by 88%. Do you think you could handle eating a spinach salad five times a week to prevent eyesight deterioriation? Many people find this easy to do.There are plenty of foods to improve eyesight.
Nutritional Eyesight Facts
We know now these nutrition facts about eyesight:
1. Low levels of lycopene were also associated with a greater chance of developing macular degeneration.
2. People with cataracts have less vitamin C in their eyes than those who don’t have cataracts.
3. Antioxidants are like sunglasses for your eyes.
4. Your retina uses the most oxygen of any of your body parts. Thus, it needs more antioxidants than any part of your body.
5. There is more zinc in your retina than in any other part of your body. Zinc allows the release of vitamin A in the liver to form rhodopsin for your eyes. It also allows the photoreceptors to work properly.
Antioxidant Functions For Your Vision
Here’s a table about a few of the antioxidants and what they do in the body to protect your eyesight from deterioration.
