Spectacles should be replaced when the prescription changes significantly, frames are damaged, or lenses are too scratched to provide clear vision. Regular reviews help identify the right time.
Signs Replacement Is Needed
Persistent headaches, blurred vision, or difficulty focusing may indicate that your prescription no longer suits your needs. Bent frames, loose joints, or badly scratched lenses also compromise vision and comfort.
- Children often require more frequent changes as their eyes grow
- Driving or safety‑critical tasks demand up‑to‑date correction
- Changes in general health, such as diabetes, can alter prescriptions
- Cosmetic wear alone is a personal preference but may prompt replacement
Routine Timeframes
Many adults benefit from an eye examination every two years, or sooner if recommended, with spectacle changes as required. Some may keep a previous pair as a spare if still reasonably accurate.
- Follow your clinician’s advice regarding review intervals
- Update glasses promptly after surgery or significant prescription shifts
- Consider occupational or task‑specific lenses when visual demands change
- Donate suitable old frames or lenses via approved schemes where available
