From the perspective of traditional Chinese medicine, the root of bad eyes is the kidney. If you want to make your eyes moist and radiant, you should eat some food that tonifies the kidney. It is better to take medicine as a food supplement, and it is very useful to do more eye exercises. Don't stare at the screen for a long time, which will easily make your eyes tired. Look at the distance for a few minutes every ten minutes to relieve eye fatigue. Get enough sleep and try not to stay up late.
