What to look for in your vision supplementMonday, 19 August 2019 | Journey
Researching the best vision supplement can be as daunting as choosing which Netflix show to watch next, and both come with equal amounts of blue light exposure.
To help reduce the impact of your screen time, here are the key factors to look for in your vision supplement.
Essential Eye Nutrients
To protect your precious peepers from digital eye strain, a quality vision supplement needs antioxidants, omega-3 DHA, and two essential eye nutrients, lutein and zeaxanthin.
Antioxidants help support healthy vision by protecting cells from free radical damage.
New Zealand Propolis is a natural powerful antioxidant, and Manuka Health’s premium concentrated extract has exceptional purity and potency.
Omega-3 DHA is essential for eye, nerve and brain health. It should also be a key ingredient in your vision supplement because it helps the body absorb lutein and zeaxanthin.
Lutein and zeaxanthin, found in green leafy veg, egg yolks, and yellow vegetables and fruit, are top nutrients that help the eyes filter blue light.
They do this by creating a layer of pigment over the retina (the light-sensitive tissue at the back of the eye) and the macula (the centre of vision).
Yep, these two star players create a built-in, blue-light filtering layer of protection. Kind of like internal sunglasses. And just like your Ray-Bans last longer than a pair of two-dollar knock-offs, a vision supplement with quality sourced ingredients offers stronger eye protection.
Quality Source, Trusted Brand
FloraGLO is considered the gold standard lutein brand. And as the number one doctor recommended lutein, it’s also the most trusted.
FloraGLO lutein is sourced in Switzerland from Marigold flowers in its natural free-form state so it's more easily absorbed by the body. Unlike humans, plants have an innate ability to make lutein and zeaxanthin naturally (as protection against UV damage, another way these two nutrients help protect against light exposure).
Because humans have to obtain lutein and zeaxanthin from food, modern diets can mean insufficient amounts. Particularly when urban living requires increasing amounts of screen time, which also increases our need for these protective nutrients.
Researched Ingredients, Effective Doses
The job of filtering blue light puts strain on your eyes in the short term, and in the same way overexposure to UV light results in sunburn (and lousy tan lines), too much long-term blue light exposure can damage the retina.
But before you rush off and buy all the lutein-laden foods you can find, it’s helpful to know how much you need.
The requirement for lutein and zeaxanthin has increased since the days when the only exposure to blue light was from the sun. FloraGLO is shown to absorb blue light and reduce eye damage caused by visible light, and provides the same amount of lutein in a daily dose that you would get from 5 cups of cooked broccoli or 40 large eggs.
FloraGLO is supported by over 20 years of research and 99 scientific studies.
Two capsules of Manuka Health Vision Shield contain the recommended dose of FloraGLO Lutein & OPTISHARP, Zeaxanthin a scientifically researched brand of zeaxanthin, top quality omega-3 DHA, and Manuka Health’s superior New Zealand Propolis, natures powerful antioxidant protector.
Vision Shield provides well researched, targeted care that protects your eyes from blue light exposure, supports healthy vision, and reduces eye fatigue.
So now you’ve found what you should be looking for in your vision supplement, you can binge-watch season 2 of Stranger Things (though you may need to shield your eyes for entirely different reasons) with a bowl of natural popcorn and blue-light protection.
That makes any weekend marathon virtually guilt-free.
