Cataracts are not a disease to put on the back burner and worry about later. Yes, over half of all Americans over 80 years old have this disease. However, it also affects younger adults, especially those that fall into certain high-risk groups. This includes people that have been exposed to radiation, people 50 years or older, people with diabetes, and those who smoke.
Sun exposure to the eyes can cause damage and increase your risk of getting cataracts, too. No matter your age right now, prevention is key when the risk of getting cataracts is so high. The best place to start is with your diet. Are you getting all the necessary cataracts vitamins?
What Are Cataracts?
Cataracts are the clouding over of the lenses causing cloudy vision or complete vision loss. This happens when the tissues that connect to the eyes’ lenses change, often from age or injury. The most common cause of cataracts is aging. For many people, cataracts are hereditary and not related to trauma or sickness.
There are, however, specific types of cataracts that have other causes. Traumatic cataracts usually occur after eye surgery. Secondary cataracts are often caused by the presence of other eyes diseases, like glaucoma. Some babies are also prone to getting congenial cataracts if their mother was suffering from measles or another disease while pregnant.
The first symptoms of cataracts are foggy vision and light sensitivity. You might notice that your night vision has decreased or that bright colors seem slightly dulled. There isn’t any pain or discomfort. Cataracts are slow-moving and you might not realize you have them until some vision loss occurs. You should see your eye doctor right away if you notice a decrease in your vision. By getting annual eye exams, your doctor can help you prevent cataracts before they happen. One way of doing so is by taking vitamins for cataracts.
It’s important to know that cataracts are not contagious. They can’t spread from one eye to another or one person to another. Sometimes they only present in one eye and not the other, sometimes both.
Which Vitamins for Cataracts Are Safe and Effective?
Getting a healthy, balanced diet is key to preventing cataracts. Like any other eye disease, being deficient in certain nutrients can increase your risk of developing them. So, which nutrients are specific vitamins for cataracts? Here are some of the most crucial.
AREDS and AREDS2 Vitamins for Cataracts
These two well-known studies looked at which vitamins could effectively prevent cataracts and other age-related eye diseases. They found in the first AREDS that multivitamins containing vitamin C, E, and zinc could slow down the progression of cataracts. And in some cases, prevent them altogether. In AREDS2, lutein and zeaxanthin were discovered to also be critical vitamins for cataract prevention.
You don’t have to change your diet or eat foods that you don’t enjoy. A multivitamin like the one used in these studies is an excellent way to get all your cataracts vitamins in.
As mention above, lutein and zeaxanthin were proven to be vitamins for cataracts in the AREDS2 study. These two carotenoid antioxidants play a huge role in general eye health. Besides neutralizing oxidative stress in the eye, they filter blue-light. This protects the macula from getting damaged and degenerating. Lutein and zeaxanthin are naturally found in the lenses of the eyes, where cataracts develop. The absence of lutein and zeaxanthin results in the lenses being unprotected from free radicals and immense damage.
You can get lutein and zeaxanthin in your diet from leafy greens, yellow peppers, and egg yolks. However, for some, it may be more convenient to take cataracts vitamins in supplement form.
Did you know that having a zinc deficiency can result in cataracts? Zinc is a necessary nutrient for the retina and choroid. Without it, vitamin A doesn’t get transferred from the liver to the retina and you’re more susceptible to infections. The body doesn’t naturally produce zinc, so you must get it from your diet or from cataracts vitamins.
Zinc is present in foods such as legumes, seeds, shellfish, and whole grains. According to the AREDS studies, people who are at higher risk of age-related eye diseases should be taking more of these crucial nutrients. It’s best that you speak to your eye doctor about dosages and zinc levels before increasing yours.
Some people are predisposed to develop cataracts later in life. However, by getting enough vitamin E, those people can delay the onset of cataracts. Others who aren’t high-risk can take vitamin E to prevent cataracts and age-related macular degeneration altogether. Vitamin E is a powerful antioxidant that protects the cells from oxidization. Cataracts are sometimes caused by the oxidization of the cells in the lenses of the eyes.
By protecting these cells from damage, you can theoretically prevent cataracts. Keep in mind that taking more than the recommended dose of vitamin E can result in unwanted symptoms. For example, muscle weakness and decreased thyroid functioning.
Besides taking vitamins for cataracts, you can get vitamin E from some food sources. These sources include leafy greens, broccoli, nuts, and vegetable oils.
Should I Start Taking Vitamins for Cataracts Prevention?
It’s always best to discuss vitamins with your doctor before you start taking them. Perhaps you already get more than enough from your diet. Or, perhaps you’re not getting nearly enough.
The key is regular checkups with the eye doctor so they can monitor your eyes’ health. Your eye doctor can assess the eyes for signs of cataracts or track the disease progression. They will likely suggest some lifestyle changes such as quitting smoking, exercising more, and getting a more nutritious diet.
They may also suggest surgery but know that this comes with many risks. If you start now, you could prevent or delay the onset of cataracts. It all starts with getting all the necessary cataracts vitamins from your diet or in a supplement form.
