For Last Few Days I Have Been Having Some Sort

For last few days I have been having some sort of pain in my eyes. Im a 17 yr old and will be answering my board exams. And I have been studying at night but I get some sleep during day time, which sums up to around 5-6 hours of sleep a day. So what's the reason behind this? Will I be needing some sort of medical attention or spectacles or its normal.
