What should my friend do about her eye problems?

Hey Fluther, this question isn’t about me, it’s about my friend. Well first off she told me that when she was in class today she couldn’t see the board at all and her eyes were hurting all day. Now she says she feels the back of her eyes hurting and she feels like her eyes are dry but they’re not and that they feel sore. She also says that when she blinks she feels like her eyes are being squished? I’m not completely sure if that might help but if you guys could help out it would be greatly appreciated. Also, she says that it’s about the same sensation as restless legs, but on her eyes. She’s pretty sure she needs glasses and I’m wondering if these are symptoms before you get glasses, and if there’s something she can do to make them feel normal again even temporarily. Any information would help :) Well, thanks in advance :)
