Proper amount of lutein for eye health

Among the large group of people who have poor vision or suffer from an eye disease, a majority has tried to get a remedy or treatment. But it is a fact that nearly no eye disorder can be cured completely. This disappointing point actually reminds us of the importance of eye problem prevention. Keeping eye health can follow different approaches. Many people believe the effectiveness of doing eye exercises. And currently, more and more people have realized the benefit of lutein in vision preservation. Lutein is believed to maintain overall eye health and ward off the onset of macular degeneration. It typically functions together with zeaxanthin, another essential substance in the eye. However, lutein dosage has aroused lots of controversies and even debates.

Lutein helps remove free radicals in the body

The exactly needed amount of lutein is not as clear as its advantages. Many people in this industry know that antioxidants including lutein can remove free radicals and other toxins. These harmful things will cause certain healthy issues over time as they build up. By removing these radicals, lutein as well as other antioxidants helps the body function better. Some areas of the body can particularly benefit from lutein. As a small area of the retina of the eye, macula is such a body part that lutein concentrates.

Lutein and zeaxanthin prevent macular degeneration

The macula is such a part that has a direct connection to lutein. Along with zeaxanthin, lutein can prevent harmful UV rays from damaging the macula, which is the central part of the retina. The concentration of lutein in macula also proves this point that lutein helps keep the eyes safe from oxidative stress and high-energy photons of blue light. A lutein deficiency can destroy this protection. As a result, the macula may be worn down by those rays over time, leading to age-related macular degeneration (AMD). Macular damage can not be undone so that taking lutein is essential to prevent AMD, which is one of the top two causes of vision loss in the old.

Relationship with cataracts and light sensitivity

The other cause is cataracts. Some study findings show that taking more lutein and zeaxanthin helps lower the risk of developing cataract, which is the cloudiness in the lens and causes blurry vision. However, the amount of these two natural antioxidants the body needs to achieve expected benefits is still unclear. There are also researchers trying to find the function of lutein and zeaxanthin in reducing light sensitivity.

Get a proper dosage of lutein from vegetables

There is actually no standard prescription of lutein dosage, which varies from person to person. The most effective way to get proper lutein dosage is to eat a well-balanced diet. Lutein as well as other natural antioxidants can be easily found in colored fruits and vegetables. Actually, the color of these plants comes from these antioxidants. Those vegetables include kale, lettuce, beet greens, squash, sweet potatoes as well as carrots.

Avoid overdose of supplements

A daily supplement can also offer enough lutein for those who have difficulty maintaining a healthy diet. Currently, there are many such products that contain various natural substances for overall body health. A common concern is that these supplements can be overdose. It is reported that excessive lutein intake may lead to a yellowish or orange skin. In this case, it is quite necessary to carefully read the label and conform to doctor’s instructions.
