Is Your Glasses Prescription Expired?

How Long Do Glasses Prescriptions Last and What to Do When Yours Expires

Is that blurriness a sign that you're overdue for a new eye exam?  If you wear glasses, it's important to understand how long your prescription is valid and what happens when it reaches its expiration date. Let's clear up the confusion around those pesky prescription expiration dates.

Why Do Glasses Prescriptions Expire?

It's not a trick by your optometrist! Your eyes change over time, often subtly. These small shifts can make your current glasses less effective, potentially causing eye strain and headaches. 

Here's the deal:

Age-related changes

Our eyes change throughout our lives, affecting our vision.

Eye conditions

Medical conditions such as cataracts or glaucoma can impact your vision more rapidly.

Lifestyle

Eye strain from factors like increased screen time can worsen eyesight.

Eye exams help your doctor monitor these changes and update your prescription.

How Long Are Prescriptions Valid?

Here's the general rule of thumb:

Adults: Most glasses prescriptions for adults expire after 1 year. 

Children and Teens: Due to more rapid eye changes during growth, prescriptions for those under 18 often need updating more frequently.

What Happens When My Prescription Expires?

Here's what you should (and shouldn't) do:

• Prioritize an eye exam

Schedule a comprehensive eye exam to get an updated prescription and check for underlying eye health problems.

• Resist using expired glasses

Frequently Asked Questions

How long is a glasses prescription good for?

Most glasses prescriptions are valid for one to two years from the date they were written, though the exact timeframe depends on your state's regulations and your eye doctor's recommendation. Some states mandate a one-year expiration, while others allow up to two years. Children and teenagers typically receive shorter validity periods because their eyes change more rapidly during growth. If your vision changes noticeably before your prescription's expiration date, it's worth booking an eye exam sooner rather than waiting for it to formally expire.

Can I use a glasses prescription from 2 years ago?

In most cases, no — a two-year-old prescription is either expired or right at the edge of its validity, depending on your state. Even if the prescription hasn't technically expired yet, your vision may have shifted enough in that time to make it less accurate. Most optical retailers, including online eyewear stores, require a valid, unexpired prescription before filling an order. If you're unsure whether your prescription is still current, check the expiration date printed on the prescription slip or contact the office where your last exam was performed.

Is it illegal to buy glasses with an expired prescription?

In most states, yes — optical retailers are required by law to verify that a prescription is current and unexpired before filling it. An expired prescription cannot legally be used at most optical stores, online or in person. This regulation exists to protect your eye health, since an outdated prescription may no longer reflect your actual vision needs. If your prescription has expired, you'll need to schedule a new comprehensive eye exam before ordering new glasses.

What happens if you wear glasses with the wrong prescription?

Wearing glasses with an incorrect or outdated prescription forces your eyes to strain and compensate continuously, which can cause headaches, eye fatigue, blurred vision, and difficulty concentrating. Over time, this added strain can make your symptoms worse rather than simply leaving them unchanged. While wearing the wrong prescription won't permanently damage your eyes, the ongoing discomfort and reduced visual clarity are good reasons not to delay updating your prescription once it has expired or your vision has changed.

Why do glasses prescriptions expire?

Prescriptions expire because your eyes are not static — they change throughout your life due to aging, health conditions, lifestyle factors like increased screen time, and natural fluctuations in your visual system. What accurately corrected your vision one or two years ago may no longer be precise enough today. Regular eye exams also allow your doctor to check for early signs of conditions like glaucoma, cataracts, and macular degeneration that may not yet be causing obvious symptoms. The expiration date is as much about protecting your overall eye health as it is about keeping your vision sharp.

How often should adults get an eye exam?

Most eye care professionals recommend a comprehensive eye exam every one to two years for adults with no existing eye conditions. Adults over 40 are often advised to go annually, as age-related changes like presbyopia and increased risk of conditions such as glaucoma become more relevant. If you have diabetes, a family history of eye disease, or have noticed recent changes in your vision, your doctor may recommend more frequent visits. Don't use your prescription's expiration date as the only trigger — if something seems off with your vision before that date, book an appointment.
