Lutein is a carotenoid found in egg yolks, avocados, cruciferous vegetables and dark green leafy vegetables. It is known for its ability to improve eyesight. Studies have also shown that it has a neuroprotective effect and can improve memory and intelligence.
Your body cannot produce lutein, so you need to supplement it through diet. Unfortunately, many people fail to supplement enough lutein simply because they do not eat enough vegetables and/or eggs.

The author of a review published in the Journal of the Public Library of Science (Plos One) in 2019 pointed out that “existing evidence suggests that dietary lutein may be beneficial to AMD patients, and higher doses can make MPOD more effective Increase in a short period of time." Lutein has also been shown to prevent cell death caused by retinal detachment. If supplemented in time, it can also help improve night vision.
