Zeaxanthin is found mainly in the central macula in our eyes
Zeaxanthin is an orange-yellow pigment which is similar in nature to lutein. It can be found in papaya, corn and Japanese Fuyu persimmon, and it is also abundant in green tea, egg yolk, and animal fat and liver. Metabolised lutein converts to zeaxanthin. It has been confirmed that zeaxanthin exist in the central yellow spot (macula lutea) of our eyes as lutein does. However, recent studies found that their concentration in the retina is different. The central macula has a higher proportion of zeaxanthin, and the ratio of lutein is higher in the peripheral area.
Zeaxanthin (along with lutein) migrates to the eyes and is drawn into lens, macula and fovea (at the retina's center). In the macula and fovea, zeaxanthin helps build the yellow macular pigment shield that protects eye cells from dangerous light frequencies.Zeaxanthin also provides powerful antioxidant activity, neutralizing the free radicals that damage eye cells.
