How often should you change your eyeglasses?

Glasses are easy to take for granted. You wear the same pair for years, they still work, so why change them? The honest answer is that your eyes, your lifestyle, and the glasses themselves all shift over time. Here is a realistic guide to when it is worth updating your specs.

The general rule: check every one to two years

Most adults benefit from an eye test every one to two years, and that is the natural moment to decide whether new glasses make sense. Children and teenagers often need more frequent checks because their eyes are still developing and their grades can change quickly. If it has been more than two years since anyone measured your eyes, you are overdue, even if your current pair feels fine.

Signs your grade may have changed

Your eyes rarely announce a change. Instead you adapt without noticing. Watch for:

• Squinting to read signs, subtitles, or your phone
• Headaches or tired eyes after screen work or driving
• Holding your phone or a menu further away to focus
• Blur that clears when you cover one eye
• Trouble with night driving and glare

Any of these is a good reason to get checked, whether or not your glasses are old.

When the frame or lenses wear out

Even if your grade is stable, glasses are worn daily and take a beating, especially in our heat, humidity, and the friction of a face mask or helmet. Consider replacing when:

• Lenses are scratched enough to distract you, which no cleaning fixes
• Anti-reflective or other coatings are peeling or crazing
• The frame is loose, bent, or no longer sits straight after adjustment
• Your lifestyle changed, with more screens, more driving, or a new job

A note on lens technology

Lens design moves forward. If your current pair is several years old, newer lenses may offer thinner profiles, better coatings, or clearer progressive designs than what you have now. That is worth weighing when you renew, because a modern lens in an up-to-date grade can feel like a real upgrade.

Do not toss your old pair

Keep your previous glasses as a backup. A spare in your bag or car has saved many people on the day a lens pops out or a frame snaps.

Not sure if you are due?

Book a Vision7 eye test at your nearest Vision Express store. The seven-step exam checks your current grade and your eye health, so you replace your glasses when there is a real reason to and not on a hunch.

If your grade has moved, ask for the Shamir Opulens Exact at the counter. It is made to your measured grade instead of being rounded to the nearest standard step, so the jump from your old pair to the new one is one you notice the moment you put them on.

If your prescription is on the strong side, ask for the Tokai BIR-W. It is a high-index lens, so the same strong grade comes out thinner and lighter, without the thick edges that make an older pair look and feel heavy on your face.

Keep the old pair in your bag as a spare. Every new pair comes with free lifetime ultrasonic cleaning and free lifetime custom fitting and adjustment, so your glasses stay comfortable between visits.
