Both prescription eyewear and sunglasses over time can stretch out and no longer fit snugly on your face. Trying to bend the plastic frames to fit again can be risky; this can warp the frame, or worse, it can snap and destroy your glasses. Since plastic is more flexible when it's warm, try this trick. Use a hair dryer to heat up the eyeglass frames, and when they are warm, mold the frame back into shape. The frame does not need to be scorching hot to be more flexible; just warm to the touch is enough to get the frames to feel custom again.
