Well, in my opinion, you should know that this situation is kind of normal. So you should not too worry about it. First, as we know that the light is so strong that when we open our eyes to see it, it will just make the eyes hurt. And also our eyes are so very sensitive that they will react to the stimulation from sun light. So when the sunlight gets into our eyes, it will make our eyes to adjust to it. Sometimes, it will also make your eyes not just hurt, but also become watery. So at this moment, you'd better wear sunglasses to protect your eyes from the strong light and the UV rays. And also, there are many dirty objects in the air outside, so when you go out, your eyes are easy to be infected by them. Just be careful about it. Anyway, you should not make your eyes to be exposed under the sunlight for a long time.
