6 Simple Steps to Reduce Vision Loss from Age-Related Macular Degeneration

The rate of vision loss is increasing for people 40 years old and older. The latest report is this vision loss is due to Age-Related Macular Degeneration (AMD). Let’s take a look (pun intended) at what you can do to beat the odds.

Major Risk Factors for AMD

Lifestyle choices -Smoking, high cholesterol and high blood pressure are risk factors for AMD

Diet -Diets lacking adequate nutrients are another major risk factor. It’s been reported that nutritional value of foods is decreasing. 2

Ultraviolet light -UV rays can also increase the risk of macular degeneration

What Can You Do?

1. Stop smoking, maintain healthy cholesterol and blood pressure levels

2. Include vision supporting foods

The right nutrition can optimize macular health, so an eye-healthy diet is important in reducing the risk of age-related macular degeneration (AMD). It could also slow the progression of AMD. In general we want a diet high in antioxidants and foods that are densely colored. Some examples:

Vitamin C - citrus fruits, berries, melons, broccoli, tomatoes, cabbage, potatoes

Vitamin E - vegetable oils, almonds, pistachio nuts, peanuts, wheat germ, whole grains, turnip greens, and mango

Beta-carotene - carrot, sweet potatoes, spinach, dark leafy green vegetables, melon, cantaloupe, winter squash, and apricots

Zinc - chicken, pork, liver, eggs, wheat germ, fortified breakfast cereals, and seafood

Copper - liver, cocoa beans, nuts, whole grains, seafood, and dried fruits

Lutein - spinach, kale, collards, Swiss chard, mustard greens, dill, red peppers and guava

Zeaxanthin - orange sweet peppers, broccoli, corn, turnip greens, collard greens, dark leafy greens, tangerines, oranges, eggs and persimmon

You can do a no-cost personalized nutrition assessment to determine if you are getting all the eye protecting nutrients that you need. Learn more by clicking here:  Meology

3. Wear Sunglasses

Wear good quality sunglasses outdoors that protect your eyes from Ultra-violet (UV) radiation.

4. Test Yourself with an Amsler Grid

Download your own Amsler Grid to test at home.

5. Computer Screentime

There are mixed messages on this topic. Does too much time spent in front of a computer screen or mobile device put you at risk of macular degeneration?  Some experts say yes and others say no. They all agree screentime can have negative influences on your circadian rhythms.
