<s>[INST] My 3 month old son s eyes hurt by direct sunlight this afternoon. I m not sure what exactly happened. When I pushed his stroller from shade to sunlight, he start crying. He didn t open his eyes for about 3 hours, and now he can not take light. We are keeping him in a dark room. Is it a serious issue? [/INST] HI...this could a serious issue. I suggest you get him evaluated by an ophthalmologist please as soon as possible.Regards - Dr. Sumanth </s>
