Lutein is often regarded by experts to be a natural form of treatment for age-related macular degeneration (AMD), which is known to be the most common cause of blindness among older adults. Estimates suggest that over 25 million across the world today are affected by AMD and cataracts. This particularly applies to people aged 55 and above, and those who are living in industrialized areas and Western nations.
The incidence of AMD is also expected to triple by around 2025, according to the American Optometric Association.
Lutein helps to protect eyesight by assisting in filtering out some of the damaging short-wavelength UV light that can be absorbed and negatively affects delicate areas within the eye. Researchers from Harvard suggest that supplementing with as little as 6 mg of Lutein can be enough to reduce the risk of macular degeneration by around 43%.
