Lutein is widely recommended by eye ophthalmologists to maintain eye health. Many people may have doubt about the effectiveness of this nutrient, because they do not know how lutein works in the eyes. The answer to lutein effectiveness in preserving eyesight is yes. But there is still some misconception in this realm. Some people may think that eye health protection is needed only when they have reached 60 years old. The fact is that preventive nutrients such as lutein are only capable of preventing eye problems, rather than curing them. So, lutein should be taken at an early age, which offers eye protection for the future.
Lutein is a natural nutrient that can be found in many green vegetables such as spinach. As a member of the carotenoid family, lutein acts as a pigment in these vegetables as well as other foods including egg yolks and plenty of fruits. This is why there are eye professionals recommending these foods as good sources of lutein.
Lutein also occurs within the retina of the eyes of a baby. This natural nutrient in the retina can filter out dangerous blue light from the rays of the sun. In this way, free radicals damaging the eye cells can be prevented. In the contrary, a lutein deficiency may lead to age-related eye diseases including the common one named macular degeneration. Many studies have proved that lutein intake can also help improve eyesight. This extra benefit in addition to disease prevention is really a significant discovery. What’s more, combined with other nutrients such as vitamins and minerals, lutein can be more powerful in improving one’s vision.
With the clear acknowledgement of lutein effectiveness, it is still necessary to know how this nutrient works. The layer of lutein in the retina is responsible for protecting the cells in this area. This natural protection is critical for daily activities such as driving, reading, drawing and so on. But the natural aging process will inevitably cause the lutein layer to thin, so that lutein intake is necessarily needed.
