Nutrients That Support the Eyes and Brain: Sage & Goji Berries

Blog-Brain and VisionDid you know that your daily habits affect your eyes and brain? As our population ages, more effort is needed to support seniors’ eyes, brains, and overall health. Research shows that a balanced diet, regular exercise, meaningful social interactions, and targeted supplements can have a significant impact. Remember, your retina and optic nerves are essentially brain tissue, meaning the nutrients that nourish your brain also bolster your vision. Read on to discover some of the latest research in this field.

Ultraviolet Light Linked to Eye Disease and Skin Damage: UV Safety

woman in sunshine wearing sunglassesJuly is Ultraviolet Safety Month, a crucial time to raise awareness about the dangers of UV rays and the importance of protecting our eyes and skin. Ultraviolet radiation, a type of energy produced by the sun, can have serious health implications if proper precautions are not taken. Why is UV safety important? What are the sources of ultraviolet radiation? How can you keep yourself and your loved ones safe from the harmful effects of UV rays?

Add Nutritional Sun Protection to Your Summer

Protection Against Sun Exposure

sun protection - girl and dadSummertime is here, and it is great to be outdoors enjoying the wonderful weather. Some daily exposure to sunlight helps build up Vitamin D in the body and is good for eye health, but excessive exposure can lead to skin damage, skin cancer, and even promote eye disease which may include macular degeneration, other retinal disorders, and cataracts. Ongoing exposure to blue light increases the risk of neovascular (wet) macular degeneration, particularly associated with low levels of antioxidants, and especially low levels of vitamin C and zeaxanthin.[1. Fletcher, A.E., Bentham, G.C., Agnew, M., Young, I.S., Augood, C., et al. (2008). Sunlight exposure, antioxidants, and age-related macular degeneration. Arch Ophthalmol, Oct;126(10):1396-403.] Another study suggested that extended exposure to sunlight outdoors may be associated with age-related maculopathy.[2. Cruickshanks, K.J., Klein, R., Klein, B.E. (1993). Sunlight and age-related macular degeneration. The Beaver Dam Eye Study. Arch Ophthalmol. 111(4):514-518.] Continue reading “Add Nutritional Sun Protection to Your Summer”

The Sun and Your Eyes: Enemy or Friend?

Does Sunlight Danger Outweigh the Benefits?

Many studies demonstrate that exposure to sunlight provides protection to diseases such as hypertension, diabetes, multiple sclerosis, and a variety of cancers, and avoiding sunlight may influence their progression.[1. Razzaque MS. (2018). Sunlight exposure: Do health benefits outweigh harm? J Steroid Biochem Mol Biol. Jan;175:44-48.]  It has been thought that these protections are due only to vitamin D, whose creation requires sunlight, but researchers are now reporting that circadian clock influencing, immune response modification, and nitric oxide, melatonin, and serotonin formation are involved as well.[2. Van der Rhee HJ, de Vries E, Coebergh JW. (2016). Regular sun exposure benefits health. Med Hypotheses. Dec;97:34-37.] In fact, researchers are finding that the risk of skin cancer increases with irregular patterns of sun exposure, while regular patterns convey relatively lower risk.  This is the difference between getting sunburned versus a brisk daily walk in the sunlight.

But too much sunlight is harmful to both eyes and skin. We know that getting sunburned increases skin cancer risk. Our vision is also directly negatively impacted by the sun and ultraviolet radiation (UVR), as well as blue light from computer screens. Continue reading “The Sun and Your Eyes: Enemy or Friend?”

Blue Light Harms Fruit Fly Eyes and Brains

fruit fly eye blue lightFindings from a recent study suggest that blue light, the same light emitted from smartphones and fluorescent light bulbs, causes brain damage and premature aging in fruit flies.

Why would research on fruit flies be important for human brains?  Surprisingly, many of the genes of fruit flies are the same as the genes in humans, and studies on fruit flies often reveal information valuable for human health. Fruit flies’ life cycle is short so scientists can see aging patterns.

As published in the journal Aging and Mechanisms of Disease, researchers at Oregon State University conducted an experiment where they subjected adult fruit flies to blue light. The targeted group of adult flies was exposed to twelve hours of blue light, followed by twelve hours of darkness. They then compared these flies to the control group. Those flies were kept in total darkness for twenty-four hours or bathed in light where blue wavelengths were blocked. Continue reading “Blue Light Harms Fruit Fly Eyes and Brains”

Save Your Vision at All Stages in Life

How can you save your vision regardless of your age? Eye disease is prevalent in seniors; however, people of all ages can take steps to protect their eyes. Here is Natural Eye Care’s guide to preserving the precious gift of sight.

At All Ages

Wear Sunglasses: The earth’s atmosphere has thinned, exposing our eyes to more ultraviolet light whenever we are outdoors. Wear 100% UVA/UVB protecting sunglasses when you are outside in the Continue reading “Save Your Vision at All Stages in Life”

Sunglasses for Driving: Protect the Eyes and Increase Safety

sunglasses for drivingWhenever the sun is shining, drivers need to wear sunglasses. Glare from the sun is unsafe and can cause accidents. The eyes are vulnerable to damage from sunlight. Which types of sunglasses are best for driving? How do sunglasses protect the eyes?

Driving Safety

New drivers have the mantra drilled into them: “Hands on the wheel, eyes on the road.” Bright sunlight streaming through the windshield is hard on the eyes. Even a slightly Continue reading “Sunglasses for Driving: Protect the Eyes and Increase Safety”

Why Lightbulb Choices Matter

lightbulbsEven though sunlight is free, we pay for electric lightbulbs. We enjoy access to light 24 hours a day, even lighting the outside at night. The miracle of electric lighting means more leisure and work time.

What effects do the different types of lightbulbs have on our eyes? On our health? Does the type of light in the evening affect our sleep cycles? We’re encouraged to use compact fluorescent and LED bulbs instead of incandescent bulbs, but are the long-effects of these new bulbs known, or can their effects be predicted?

Outdoor Activities Associated with Eye Disease

outdoor jobs and visionSunlight is critical for overall well-being.  Through an intricate process it enables the body to produce essential vitamin D.  We only need 20 minutes of sunlight a day.  But sunlight also contains UV radiation.

Unprotected over exposure to sunlight can eventually result in oxidative damage to the retina and other eye tissue such as the eye lens and sclera causing many eye problems as well as skin cancer. You can help protect your eyes by wearing 100% UVA/UVB protecting sunglasses when outside (particularly wraparound glasses with amber or brown lenses that are polarized to reduce glare).
