How Often Should You Replace Your Glasses?
There is no fixed date to replace glasses, but most people do it every one to two years. These signs tell you it is time.
Your prescription changed
If you squint, get headaches or see blurry with your current glasses, schedule an eye exam. Many adults get checked every one to two years.
The lenses are scratched
Scratches in the center of the lens scatter light and reduce sharpness. They cannot be polished out; the lens has to be replaced.
The frame no longer holds
Loose hinges, bent temples or a frame that keeps sliding down make your lenses sit in the wrong position, which affects your vision.
You need something new
Starting a screen-heavy job, driving more at night or turning 40 (reading gets harder) are good moments to update your lenses.
Frequently asked questions
Can I put new lenses in my old frame?
Sometimes, but it is often similar in price to a new pair with lenses included, and an old frame may break during the process.
Should I keep my old glasses?
Yes, as a backup pair if the prescription is close to your current one.
