The Benefits of Lutein & Zeaxanthin for Vision

Lutein and Zeaxanthin may sound like the names of some suspicious looking aliens from a long-forgotten B-movie, but they are actually rather interesting anti-oxidants that are said to have excellent benefits for vision. They are chemical compounds of the caretenoid family and both contribute to a carrot's orange colour as well as the yellow in other plants.

Not only do they provide colour to the world's vegetables and plants, but they are highly present in leafy green vegetables such as broccoli, spinach, kale and asparagus and are a key part of our diet for preserving the health of our eyes. Studies have shown that huge reserves of Lutein and Zeaxanthin are found in the lens and retina of the human eye and that a strong level of both is necessary to preserve healthy vision.

The way they are supposed to work is two-fold. Firstly they filter out high energy blue light that can be damaging to the eye, but secondly and more importantly, they act as a barrier to free radicals that can be extremely dangerous to the eye, both impairing vision and causing cataracts in extreme cases.

Free radicals are unstable molecules that can damage otherwise healthy cellular tissue structures, including those found in the eye. The skincare industry is also highly aware of the damage that free radicals can do to human tissue and there are many products on the market designed to protect skin from this.

In terms of eyesight, the best way to protect against dangerous free radicals is to keep a good level of Lutein and Zeaxanthin by keeping a healthy diet of leafy green vegetables, and indeed carrots: possibly the source of the urban myth that carrots help you see in the dark.

As our modern diets have deteriorated however, many people fail to do this, and increasingly people are relying on dietary supplements for their vitamins and minerals. As such, many products, such as Higher Nature's VisualEyes have cropped up in order to supplement diets lacking in crucial Lutein and Zeaxanthin to help maintain healthy vision and protect against cataracts.

Although the best way to keep up solid levels of caretenoids in the diet is to eat plenty of fresh fruit and vegetables, it is recommended that you eat 5 to 9 servings a day in order to have sufficient Lutein and Zeaxanthin in your diet, a challenge that many people will fail to meet considering the challenge they find in just 5 portions a day. As such, natural health supplements are a course of action well worth considering for those concerned about their eyesight, and people well used to taking vitamins should be well used to the idea.
