Short answer: yes, in most cases. Replacing the lenses in a frame you already own is one of the most common jobs in an optical lab, and it is usually cheaper and faster than buying a whole new pair.
When it works
- The frame is structurally sound: no cracks at the hinges or bridge, and the plastic has not gone brittle.
- The frame has a full rim or a semi-rimless groove that is still intact. Full-rim frames are the easiest.
- Your prescription has not changed, or you have a current prescription for the new lenses.
When it does not
- Very old plastic frames can crack when the lab heats them to insert the new lens. An optician will tell you the risk before cutting lenses.
- Some rimless frames use drill mounts that do not survive a second lens change well.
- Extremely strong prescriptions can be too thick for a thin or wide frame.
Do I need a new exam?
Not if you just want the same prescription in better lenses. In Georgia a licensed dispensing optician may duplicate lenses without a prescription. The optician reads your existing lenses on a lensometer, confirms the measurements, and cuts new ones to match. If you want a different prescription, you will need a current one from an eye doctor.
What you can change while you are at it
- Anti-reflective coating, which cuts glare for night driving and screens.
- Scratch-resistant hard coat.
- Thinner high-index material for stronger prescriptions.
- Tint or polarization to turn an old pair into prescription sunglasses.
- Blue-light filtering, if you want it.
How long does it take?
With an on-site lab, many single-vision lens replacements are done the same day. Progressive lenses and specialty materials usually take a few days because they are surfaced to order. Best Chance Optical in Forsyth cuts lenses in-house. See how lens replacement works or just bring the glasses in.
