As we get older, the eyes become more vulnerable to damage and the harmful effects of screen-emitted blue light (junk light). Eye Defense™ is designed to support strong eyes and better vision at any age. Research suggests that the compounds in Eye Defense™ may support long-term eye health and protect against the harmful effects of blue light from extended screen time.
Lutein and Zeaxanthin Isomers
Lutein (L) and zeaxanthin (Z) are collectively known as “macular pigments.” These are dietary carotenoids located in the eye that lend support to the center of the macula--the region of the eye most susceptible to photo-oxidative damage.  L and Z act as filters of high-energy blue light to support healthy vision and protect against oxidative stress and inflammation.  Higher intakes of L + Z are associated with a reduced risk for degenerative eye disorders like age-related macular degeneration (ARMD). [3, 4, 5] Lutemax 2020 features a 5:1 ratio of lutein-to-zeaxanthin, the same ratio found in nature that is shown to maximally support eye health.
Vitamin A (beta carotene)
Vitamin A is a fat-soluble nutrient with potent antioxidant effects throughout the body. The nutrient supports better vision by protecting the surface of the eye (cornea) and by combatting eye-related inflammation.  In combination with other antioxidants such as vitamin E, lutein, and zeaxanthin, vitamin A has been shown to play a key role in decreasing the risk of vision loss from macular degeneration (AMD).  A lack of adequate vitamin A causes the cornea to become dry, leading to vision problems like clouding in the front of the eye, ulcers, and vision loss. 
Vitamin E (d-alpha tocopherol)
Vitamin E is another powerful antioxidant compound that helps protect cellular structures from free radical damage and other metabolic debris.  Research suggests that vitamin E may have a protective effect against the formation of cataracts and the onset of AMD.  In a study done on more than 5,000 people, subjects who took a daily vitamin E supplement had a 25% lower risk of developing AMD.  Another study found supplementation of 400 IU of vitamin E per day was associated with a 60% lower risk of developing cataracts. 
Sea Buckthorn Oil
Sea buckthorn oil has been shown to reduce symptoms of dry eyes and scratchiness by stimulating the eye’s natural lubrication response.  Derived from the fruits and berries of the Sea Buckthorn plant, this unique ingredient is rich in vision-boosting carotenoids and tocopherols, and contains essential fatty acids to support the body’s natural defense against eye-related inflammation and tissue damage.
