Experts across the world agree to the fact that eyesight and vision are crucial for humans to lead a normal and happy life and those who are affected by vision loss or issues with their eyes struggle much more than those who have problems with other sensory organs. Thanks to the importance accorded to eyesight, researches are constantly being carried out to identify why people lose their vision and why there are issues with our eyes. Almost all the researches have proved that if lutein levels in the eyes go down, it may trigger issues such as vision loss, cataract, etc. Let us now find out why lutein for the eyes is important.
Experts firmly believe that the macula of the eyes has lutein in it. Lutein remains cozily in a small area inside the retina and exercises complete control over the aspect of the 3-dimensional view we get when we look at objects. Experts also believe that lutein can help people detect polarized light. Lutein also helps in combating the oxidative stress caused by free radicals that seem to be omni-present. It can safeguard the eyes from the high-energy photons let out by blue light. Though there are a few other experts who brush aside these opinions as hypothetical, there is concrete evidence to prove that a direct relationship exists between the lutein we consume and eye pigmentation.
According to the findings of several researches, if the pigmentation of the macula increases, risks of issues with the eyes such as macular degeneration due to aging or other reasons, etc. go down. Random clinical trials have also proved that lutein helps in improving visual functions. In fact, lutein with other nutrients can do wonders for the visual health of people. In other words, lutein can help in countering macular degeneration caused by various reasons including aging.
Studies have also proved beyond doubt that lutein reduce risks of issues like cataracts. Foods like corn, egg yolks, green and leafy vegetables, and a few types of fruits contain lutein but unfortunately, we do not take the required steps for ensuring that we get adequate amounts of lutein by consuming these foods regularly. So, lutein supplements can compensate for shortfall, if any, we may face in getting lutein.
Photophobia, or “abnormal human optical light sensitivity”, may also affect those who do not consume an adequate amount of lutein. This fact has been corroborated by research, the findings of which have appeared in a particular issue of the Journal of Food Science. In short, lutein supplements can improve visual performance in users and bring down the risks related to light sensitivity in them.
To summarize, lutein supplements can help in overcoming issues such as macular degeneration, cataracts, and photophobia.
