Americans who are 40 years of age or older have likely noticed changes in their vision.
They often experience difficulty seeing clearly for reading and or work.
According to the Kansas Optometric Association (KOA) adding certain nutrients to one's diet everyday through supplements or foods can help preserve vision and prevent age-related blindness and diseases.
Lutein and zeaxanthin can be found in colorful fruits and vegetables like broccoli, spinich, kale, corn, grenbeans, peas, oranges and tangerines.
Essential fatty acids are in fatty fish like tuna, salmon, or herring, whole-grain foods, chicken and eggs.
Vitamin C promotes eye health.
You can find vitamin C in fruits and vegetables including oranges, grapefruit, strawberries, papaya, green peppers and tomatoes.
Vitamin E is essential to eye health.
Foods rich in vitamin E include, vegetable oils like safflower or corn oil, almonds and pecans, sweet potatoes and sunflower seeds.
Zinc is another must-have for healthy eyes.
If you consume extra lean red meat, poultry, liver, shellfish, milk, baked beans and whole grains then your diet is rich in zinc.
The KOA recommends adults over age 60 have a comprehensive eye examination once a year or more frequently if there's a vision problem.
