Therefore, these two components are also called macular pigment. Don't underestimate these two kinds of macular pigments, they can play a very important role in protecting the eyes.
Because they can block blue light and reduce the harm to eyes. Blu-ray is very common in our life now, especially in the digital products we use every day. If blue light irradiates the retina for a long time, it will cause cell decline and lead to low vision, which is irreversible.
The existence of macular pigment can prevent the macular part of retina from being damaged by blue light and keep the sensitivity of eyes. Furthermore, lutein and zeaxanthin are also very good antioxidants, and supplementing these two elements can also reduce the occurrence of cataracts.
In particular, the human body has no way to automatically synthesize lutein, which needs to be ingested from the food it usually ingests. There are many foods rich in lutein, such as spinach, asparagus, corn and pumpkin.
In addition to lutein and zeaxanthin just mentioned, anthocyanins can also play a certain role in protecting eyesight.
Because anthocyanin is a kind of substance with strong antioxidant capacity, supplementation of anthocyanin at ordinary times can eliminate eye fatigue and make vision more acute.
