Frame Replacement vs Lens Replacement: Which Makes More Sense?

When something is wrong with your glasses, it can feel as if you have only two choices: buy a whole new pair, or live with it. In practice there are three: replace the lenses and keep the frame, replace the frame and keep the lenses, or replace both. Which makes sense depends on which part has the problem.

When replacing only the lenses may make sense

• The lenses are scratched, worn or have a damaged coating, but the frame is in good condition
• Your prescription has changed, and the frame is still comfortable and suitable
• You want a different lens type or coating in a frame you like

Lens replacement may be possible if the frame is suitable and in good condition. The frame needs to be checked for compatibility with the new lenses, because some designs, such as very thin rims or certain rimless mounts, are not suitable for every lens type. See can scratched lenses be repaired?

When replacing the frame (or the whole pair) may make more sense

• The frame is cracked, fatigued, or repeatedly out of adjustment
• The hinge or joint is damaged and cannot be repaired
• The frame no longer fits comfortably or looks the way you want
• The frame is too old or fragile to take new lenses safely
• The cost of repair and new lenses is close to the cost of a new pair

When the existing lenses can move into a new frame

This is less common than people expect. Lenses are cut to the shape of a specific frame, and they are positioned using your PD and the frame's measurements. A new frame is usually a different shape and size, so lenses are normally re-cut and re-made rather than moved. If anyone suggests reusing them, ask how they will be fitted and whether it is suitable.

A simple way to decide

1. Which part is the problem: frame, lenses, or both?
2. Is the frame sound? A professional check tells you.
3. Is your prescription current? If it is old, think about a fresh eye test before replacing lenses.
4. What are the real costs? Ask for a quote for each option: repair, lens replacement, new frame with new lenses.
5. How much do you like the frame? That is a legitimate factor.

Get it assessed first

Whether replacing the lenses in your existing frame is possible depends on the frame and its condition. Bring the spectacles in for assessment, with your prescription if you have one, and compare the options before you decide. See also repair versus replacement.
