Do I need gles? Please help!?

It sounds like you could be showing early signs of myopia (short-sighted) which is when objects can seem blurry if you are standing too far away. I suffer from myopia, and when I first developed it about 3 years ago, I found that things were becoming blurry, and my eyes were hurting from eye strain. So, I would go to the optometrist, and get your eyes checked out. You may even just need low prescription gles like your friend. I have the same thing, and everything is perfectly clear when I wear them. Good luck!
