How often should you replace your glasses?

Wondering when it’s time for new glasses or lenses? On average, people keep the same pair for about 3.8 years. That’s quite a while—especially considering it’s best to have your eyes checked at least once a year. Your eyes and vision change over time, so staying on top of your prescription is essential.

Below, you’ll find a quick checklist to help you decide if your frames or lenses are due for an upgrade.

1. Do you need a new prescription?

This may seem obvious, but it’s the most important question. If your vision is no longer crisp at certain distances, your prescription may be outdated. Difficulty reading fine print, struggling to see road signs, or frequent headaches can all be signs you need a new strength. Since your eyes change constantly, regular testing is key.

2. When was your last eye test?

If it’s been a while since your last exam—or you’ve noticed a sudden change in your vision—it’s time to book an appointment with your optician or ophthalmologist.
Here’s a general guideline for check-ups:

  • Under 18 years: Every 6 months
  • Ages 18–39: Once a year
  • Ages 40–64: Every 2 years
  • 65+: Once a year

Many people over 40 postpone replacing their glasses—especially progressive lens wearers—because of the cost. But using outdated lenses can impact your vision comfort and overall eye health.

3. Are your lenses still in good condition?

Check for scratches, dullness, or worn anti-reflective coating. Damaged coatings can’t be repaired and may cause more glare and strain. Common causes include cleaning lenses with harsh products, using paper towels, or exposing them to high heat (like from a hairdryer). If your lenses are damaged, replacing them is the best solution.

4. Is it time to replace your frame?

Signs of frame wear include cracks, discoloration, or loose parts. With proper care and storage in a case, frames can last for years. At Glazoo, we can fit new lenses into your existing frame—even vintage styles. Small repairs like replacing nose pads or temple tips are also possible.
