Well, for many people, it is common to have burning eyes at the end of the days. And for the causes, there are many ones you have to consider. For example, it may be because your eyes do not have enough water, and they are too dry. In that way, your eyes will feel burning. Also, if you have a hard work in a long time, your eyes will suffer high eye pressure. And then, that will lead to burning eyes too. So maybe you should have a good rest to relieve the situation. Or have some water. Of course, you can just take some eye drops to your eyes, so that it can moisten your eyes. And then the cool ice can be effective too. Also, you should eat a diet rich in fresh fruits and vegetables which provide lots of antioxidants, especially vitamins A and C and then do a good job to your symptom.
