Add Nutritional Sun Protection to Your Summer

Protection Against Sun Exposure

sun protection - girl and dad Summertime 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”

Lutein, Zeaxanthin, Meso-Zeaxanthin – An Update

Your Eyes Benefit from Lutein, Zeaxanthin, and Meso-zeaxanthin

food high in Lutein, Zeaxanthin, Meso-zeaxanthin Lutein, zeaxanthin, and meso-zeaxanthin are potent antioxidants found in green leafy vegetables, eggs, corn and even chocolate. They have a profound effect on preserving healthy vision, brain function, the immune and cardiovascular systems.

New research is focusing less on the well-established understanding of local benefit from nutrients, e.g. lutein for macular degeneration or cataract, and more on its systemic benefits affecting the immune system, the brain and cognitive function, the eye, cancer, and cardiovascular health.[1. Buscemi S, Corleo D, Di Pace F, Petroni ML, Satriano A, Marchesini G. The Effect of Lutein on Eye and Extra-Eye Health. Nutrients. 2018 Sep 18;10(9):1321.] In addition, new research is focused on the “why” of the benefit of these carotenoids.

Macular Degeneration

Macular degeneration (AMD) is one of the leading causes of vision loss and blindness. Our retina is abundantly supplied with oxygen but repeated or prolonged exposure to light, especially UV and blue light, decreases long-chain polyunsaturated fatty acids (such as omega-3s) in the retina, increases certain molecular bonds (lipid conjugated dienes), and degrades the photoreceptors and retina.[2. Johra FT, Bepari AK, Bristy AT, Reza HM. (2020). A Mechanistic Review of β-Carotene, Lutein, and Zeaxanthin in Eye Health and Disease. Antioxidants (Basel). Oct 26;9(11):1046.]

Accumulated exposure to UV and blue light can cause accumulation of free radicals, oxidative stress, accelerate vision loss, and hasten breakdown of photoreceptor cells which are essential for vision. Continue reading “Lutein, Zeaxanthin, Meso-Zeaxanthin – An Update”

Homeopathy and the Eyes

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?”

Nutrients for Cataracts: New Research, New Package

Cataracts are one of the most common eye conditions among seniors. A cataract results in clouding the vision, and eventually causes blindness if not treated. The conventional approach to cataracts is to wait and see if it gets worse. When a cataract is advanced, an eye surgeon usually offers cataract surgery. Cataract surgery uses artificial lenses that correct any clouding due to a cataract. It can correct certain refraction errors at the same time. However, not everyone is a good fit for this treatment. Which nutrients help promote healthy lenses and overall eye health? What does recent research into cataract pharmacotherapy show? And, which combinations of nutrients are the most effective for lens support? Continue reading “Nutrients for Cataracts: New Research, New Package”

Eye Floaters in the Vitreous: A Guide by Natural Eye Care

vitreous floaters Have you ever noticed specks or clouds in your field of vision? They are most likely eye floaters. Floaters can look like cobwebs, blobs, dots, or little insects that float around. Eye floaters can be semi-transparent or darker. If you have them, they are more noticeable in certain lighting conditions, such as bright sunlight. You might not notice them at all unless you are looking for them. Continue reading “Eye Floaters in the Vitreous: A Guide by Natural Eye Care”

Blue Light Harms Fruit Fly Eyes and Brains

fruit fly eye blue light Findings 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”

Why Astaxanthin Helps Prevent Sun Damage

Astaxanthin protects from sun damage Astaxanthin is a potent antioxidant that helps prevent sun damage to the body by blocking free radical damage. This bright red molecule forms in certain algae, pink seafood, and yeast. Unlike beta-carotene, this carotenoid crosses the blood-brain barrier to help maintain healthy brain function. Astaxanthin helps the brain by promoting neurogenesis, the generation of new brain neurons. This nutrient also supports existing neurons by reducing oxidative stress. Scientists have found that astaxanthin can protect against cumulative sun damage to the eye. This nutrient may help reduce the risk of eye disease such as macular degeneration. It may also protect against cataracts and vision loss from glaucoma. In addition, related carotenoids called lutein and zeaxanthin block blue light and work synergistically with astaxanthin.
