Pls no worries, because it is a piece of cake to adjust the crooked glasses frame. If you just bought your glasses for short time, then you can take them back to the shop and the pros will adjust for you, of course, they will do it free to charge. If they glasses are your old friend, then I think only you can help them without fees. Here I will tell you how to adjust it, because I often do it fro myself and my little brother. First of all, you should prepare some items for your first try; steam, cloth and your crooked glasses frame. Then, you should check how does the frame crooked, later you can warm your loved frame over steam. And try to blend them accordingly with the cloth. At last, you can have a good visibility with the help of the glasses. Hope I can help you out.
