My father bought a pair of reading glasses on the street. He said that this pair of glasses can help correct his vision problem. I asked him to have his eyesight checked, but he refused to do that because he thought it would be waste of money if he spent some money to have an exam and then buy a pair of reading glasses again. I don't agree with him but I also can't convince him to buy a pair of new glasses. Dude, if you want to save money as my father did, I would like to tell you that you may choose a wrong way to save money. You should have an eye exam and then buy a pair of prescription glasses that can help correct your vision problem. You can get a pair of prescription glasses in any local optical shops or online eyeglasses stores or even from a pedlar on the street. But I would like to tell you that you'd better buy a pair of glasses with good quality. The glasses sold by pedlar on the street are not my choice because I think their glasses are with poor quality. Hope this helped!
