You need to find out whether it's your eyes or taking vitamin e. I've never done this before. You said your eyes felt tired and blindfolded. Maybe you use your eyes too much. Now I spend more than ten hours in front of the computer every day. Now I always feel that something is blocking my eyes when I look far away. This is a symptom of overuse and poor eyesight. . . . You can think about whether your eyes are overused in your life and work during this time. If not, you can stop taking vitamin E for a week. If it's okay, it's a vitamin problem. If your eyes are still the same, it's your eyes, not vitamins! ~~
