The essence of the cheapest eyeglasses frames is to fix the optical center point of the lens on an object in front of your pupil. After changing the frame, any horizontal or vertical deviation, or skewness (with astigmatism) is not good!

If your lenses have been worn for 2-3 years, I suggest replacing them directly because lenses also have a lifespan. If your lenses are new and have no signs of wear and tear, they can be used. The best way is to find a matching best place to buy eyeglasses and get the same style of eyeglass frame to install.

Because the lens's best place to buy eyeglasses is processed based on this frame, this is the best option without any changes. This will not affect the pupillary distance, pupil height, or astigmatism axis!

If this eyeglass frame is out of stock, it is also possible. If you can wait a few days, I suggest waiting for a few days. If it is necessary to replace it with other styles, the key is to pay attention to whether the position and width of the beam are consistent with the beam in your broken frame. That is, whether there is any deviation in the horizontal direction.

If you have an independent nose pad, try to find one because the presence or absence of a nose pad can affect pupil height. Independent nose pads often have lower pupil heights, while integrated nose pads often have higher pupil heights. That is, whether there is a deviation in the vertical direction.

If it needs to be ground before installation, it depends on whether there are many parts that have been ground down, whether it is the nasal part, and if so, whether it will cause the lens to shrink towards the nose. If it shrinks, it may affect the distance between the pupils.
