Well, generally speaking, it is normal to have that kind of symptom. First, you should make sure if the reading is the cause of your eyes. Because even if you are reading, there are also many reason which can cause your eyes become watery. And if your eyes are still painful after reading, it may be your eyes pressure which can cause this. As we know that when we read for a long time, our eyes have to focus on one point for a long time, at that moment, it will make your eyes feel stressed. And then have painful feeling. So, at this moment, you should probably read less and make your eyes have enough time to rest. And you also should better go and see a doctor so that they can give some treatments. On the other hand, you should know that infection and irritation can also make your eyes pain so much, so you'd better pay more attention to them too.
