Lutein antioxidant for the eye

There are so many health supplement nowadays and people just can't get enough of it. There is this one eye supplement that has been trying make a name in my country, I'm not going to tell the brand, but what is important to me is to know exactly what makes this supplement, different from the other ones, What is it that make it work? and does it have any side effects? and stuff like that. So, What is Lutein?

Lutein is another antioxidant that is one of the caretenoids these are pigments that are usually found in different types of vegetables and fruits, such as squash, carrots, mangoes, sweet potatoes, tomatoes, corn and dark, leafy vegetables like those of kale, collards, bok choy and spinach. but what exactly does lutein does to help us?

Studies indicate that lutein plays a vital role in reducing the risk of AMD or also known as Age-related Macular Degeneration and can also help slow down the progression of the disease. Lutein deposits in the macular - the part of the eye that controls accurate vision - and helps filter out harmful blue light which stops it from reaching and damaging the sensitive back tissue of the retina, effectively acting as natural sunglasses.
A lot of people may not need to take any supplements like Lutein, especially if they have well balanced diet and a higher intake of lutein-rich foods, but for those people with serious eye problems, a supplement wouldn't hurt. but better check your doctor first.
