Although glasses often slide up your nose and pushing them up can be annoying, it's easy to pull them tight. If your nose frame is metal, use your thumb to shrink the nose pad until the frame no longer slides. If you have plastic frames, soak the arm in warm water for 30-60 seconds, then apply slight downward pressure to the end of the arm.
