A dear friend of mine wear eyeglasses all the time because he is having a problems of her vision, ever since we were young, I remember asking her if I could borrow her glasses so I could try it on, when I did put it on I notice some changes on my vision and it made my eyes hurt. After that I never ask to borrow her
eyeglasses again, until now she still wears them, it turns out that only a lasic surgery can correct her vision but they couldn't afford it yet.
If you are looking for an affordable eyeglasses, you should check out Zenni Optical... they offer a wide variety of prescription glasses that you can choose from. I have so many friends who uses eyeglasses way back when we were in school and usually they are very smart at school, I even wish that I wear those glasses to make me look smart, but I guess thats not gonna happen because my vision is perfect.
