Prescription lenses are ground to fit the frames. They may or may not fit the the new frames properly. The best thing to do is take the glasses and the frames to an optomotrist.

Why is a pair of glasses a pair if its only one?
When you say "glasses", it is plural. A "glass" is one of the lenses. "Glasses" would refer to both of the lenses, and a "pair of glasses" doesn't mention anything about the frame, but it mentions the two lenses. The frame is the object that joins the two lenses so you don't have to wear contacts and so it can stay on your head. When you say "a pair of glasses", you are referring to the "pair of lenses", not the frame. The frame holding the two lenses makes us think that it is one object, when the word "glasses" refers only to the lenses, not the frame. That is why it is called "a pair of glasses".

I had the same question, so I asked Endura. * With your thumb and forefinger, grasp the frame firmly at the centre of the glasses (above the nose piece). * With the other hand, grasp one of the lenses close to the nose piece between thumb and forefinger. * Pull the lenses downwards firmly away from the frame. They should release with a bit of effort. To insert other lenses, reverse the process... * Align the new lenses to the slot in the frame. * Hold the lens between thumb and forefinger close to the nose piece. * Whilst holding the frame firmly at the centre with the other hand, push the lenses firmly upwards into the frame. It should click into place.

How do you remove rimless lens from glasses?
1Check lenses for any cracks or chips that might prevent them from staying in the frame. 2. Loosen the screws that hold the lenses in place on each side of the frame if it is metal. Firmly grip the frame as you loosen the screws. Try not to totally remove the screws, just to loosen them. If they do come out, stick them on to a piece of tape to avoid losing them.If the frame is plastic, place it in warm water and let soak a few minutes to soften the plastic. This will make the frame more pliable and allow you to insert lenses more easily. 3. Inspect the lens to make sure you have the correct lens for the eyepiece. You can hold both lenses over the frame to match up proper sides. 4. Grip the frame firmly with one hand and with your other hand slide the lens into the back side of the frame, toward the middle, inner edge (the part closest to your nose). The lens should seat into the rim of a metal frame. For a plastic frame, as you insert the lens into one side, the other side of the lens should be able to be gently snapped into the frame. Take care not to push too hard or the lens could chip. 5. Repeat warming a plastic frame if the first attempt does not work, or to insert the second lens. Tighten screws back into a metal frame after lenses are in place.
