It depends. Before you fix your glasses, you shall check which part of your eyeglasses need be fixed. If they just lose their screws. Just tighten them with screwdriver. Or if the titanium glasses frames are badly hurt, do not try to solder or weld a titanium frame because it is really dangerous. You'd better buy a new pair. In fact, it is really difficult for layman to fix a damages eyeglasses frame. Or you can ask an optician to fix the eyeglasses frame for you.
Well, it may sound kind of easy, but I can assure you that they are definitely not easy to do. Anyway, I would love to share the ways with you. First of all, you need to dry your frame and your lenses. You have to know that wet frame and lenses could make it very hard for you to repair them. By the way, may I know what part of your glasses is broken? Different parts of problems need different ways of repairy. You had better use a special screw to fix your glasses or you may fail that. But to be honest, I still strongly suggest you to go to an optical store to have your glasses fixed.
Clean and dry both the frame and lenses. Use soapy warm water to wash and dry the lenses and wipe with a soft cloth or towel. Do not use paper towels on lenses. Remove any remnants of old glue if a previous repair has been done. Squeeze together any hinges that have spread out by gently using pliers to compress each side of the hinge. Use caution and squeeze very slightly; only light pressure is needed to move hinge pieces. Insert and replace the temples, also called the "arms," if they have become detached from the front of the frame. Insert the lenses if either or both have come out. Secure screws just tight enough to hold the lenses in place. If necessary, dab a drop of glue with a toothpick into the eyewire, the part of the frame that holds the lenses in place, to stabilize the lenses. Tighten any loose screws in the frame. Screws may be located in the temples, the eyewire, and there may also be screws in the nosepads that hold the pads to the frame. Do not try to solder or weld a titanium frame. Repairs done this way will crack and damage the frame material. If your titanium frame is broken to the point of needing soldered, an optical retail shop may be able to fix the frame or send your frame to a lab that specializes in titanium repairs.
