Lutein exists in many foods, but its content is relatively small.

Lutein is a nutrient that people can absorb when eating raw fruits and vegetables, but its absorption and utilization rate is generally low. If lutein is deficient, you can take supplements. If there are elderly people with poor digestive system, lutein can be supplemented by sublingual spray. Lutein has been added as a dietary supplement as early as 1996. In addition, excessive absorption of lutein will cause unnecessary burden to the liver, and the recommended dose is about 6 mg per day. No human studies have proved that eating lutein can prevent eye diseases. The real prevention of eye diseases depends on avoiding excessive use of eyes and resting them regularly. Please consult an ophthalmologist before eating lutein.

If your eyes are dry, you can also eat cranberry capsules. Very effective.

If it is vision loss, you should go to the hospital for examination and diagnosis.
