How Often Should You Update Your Glasses Prescription?

If you've been squinting at street signs or rubbing your eyes at the end of a workday, it might not be "just tired eyes." It could be a sign that your prescription is out of date. Vision changes gradually, which makes it easy to miss — most people don't realize how much their eyesight has shifted until they put on an updated pair of glasses and everything suddenly looks sharper.

So how often should you actually be updating your prescription? Here's a simple breakdown.

The General Rule: Every 1–2 Years

For most healthy adults, eye care professionals recommend a comprehensive eye exam every one to two years. Even if your vision feels fine, regular exams catch small changes before they become noticeable problems — and they check for underlying eye health issues that have nothing to do with how well you can read a menu.

It Depends on Your Age

Your eyes change at different rates throughout your life, so your ideal exam schedule shifts too:

- Kids and teens: Vision can change quickly during growth spurts, so annual exams are usually recommended.
- Adults 18–40: Eyes are relatively stable during this range. Every two years is typically enough, unless you notice changes or have a condition like diabetes that affects eye health.
- Adults 40+: This is when presbyopia (age-related difficulty focusing up close) tends to kick in. Annual exams become more important, and this is often when people start needing reading or progressive lenses.
- Adults 60+: Annual exams are strongly recommended, since risk for cataracts, glaucoma, and macular degeneration increases with age.

Signs You Need a New Prescription Sooner

Don't wait for your scheduled exam if you notice:

- Frequent headaches, especially after reading or screen time
- Squinting to see things clearly, near or far
- Eye strain or fatigue that wasn't there before
- Holding books or phones farther away (or closer) than usual
- Difficulty driving at night or seeing road signs
- Blurriness that glasses cleaning doesn't fix

Any of these can mean your current lenses are working harder than they should — and an eye exam is the only way to know for sure.

Prescription Expiration Is a Real Thing

Most prescriptions are only valid for one to two years, depending on your state and your eye doctor. Even if your eyes haven't changed dramatically, an expired prescription means you legally can't reorder the same lenses without a new exam. It's worth checking the expiration date sitting in your file (or on your last pair's paperwork) so you're not caught off guard.

Why Updating Matters More Than You Think

Wearing an outdated prescription doesn't just mean slightly blurrier vision — it can cause real eye strain, worsen headaches, and in some cases mask early signs of eye conditions that are much easier to treat when caught early. Fresh, accurate lenses also just make daily life easier: sharper vision at work, more comfortable screen time, and safer driving.
