In an environment exposed to the sun, people often wear sunglasses to protect their eyes. Interestingly, there is also a pair of "natural sunglasses" in the human body that protects the retina of the eye at all times. This pair of "sunglasses" is called macular pigment. Lutein and zeaxanthin are the main components of this pair of "sunglasses".
Once the human body is deficient in lutein and zeaxanthin, the eyes will be easily injured, and diseases such as cataracts and age-related macular degeneration will occur, leading to visual impairment and even blindness. Therefore, adequate intake of lutein and zeaxanthin is a very important part of preventing these eye diseases and delaying eye aging.
Macular lesions can cause blurred vision, black holes or distortion of vision. As shown in the figure, the heavier the lesion, the larger the black hole.
