Nature's Bounty Lutein Blue is a unique eye health supplement that helps filter damaging blue light from electronic devices such as phones and tablets.

General description Lutein is an antioxidant that occurs naturally. It protects and improves eye function. It is part of a group of substances called carotenoids. Lutein and other carotenoids, such as zeaxanthin, may help prevent or slow macular degeneration.

A large body of evidence shows that lutein has several beneficial effects, especially on eye health. In particular, lutein is known to improve or even prevent age-related macular disease which is the leading cause of blindness and vision impairment.

Lutein is a carotenoid found in the macula and retina of the human eye. Often referred to as the "eye vitamin," it is thought to work as a light filter and protect the eyes from sun damage.

Lutein and zeaxanthin are made only by plants, so animals normally get them by eating plants. Highest concentrations are found in dark green leafy vegetables such as kale, spinach, swiss chard, and mustard and turnip greens − although these nutrients are also found in a variety of other vegetables (see table, below).

Consuming up to 20 mg of lutein daily as part of the diet or as a supplement appears to be safe. Pregnancy and breast-feeding: Lutein is likely safe when used in the amounts found in food.

Recommended level for eye health: 10 mg/day for lutein and 2 mg/day for zeaxanthin. Safe upper limit: Researchers have not set an upper limit for either. Potential risks: In excess, they may turn your skin slightly yellow. Research seems to show that up to 20 mg of lutein daily is safe.

Constant exposure to blue light over time could damage retinal cells and cause vision problems such as age-related macular degeneration. It can also contribute to cataracts, eye cancer and growths on the clear covering over the white part of the eye.
