If you have recently stumbled upon an old pair of glasses while cleaning out a drawer, you might wonder, “Can I still wear these?” This is a perfectly reasonable question, especially if your current glasses are scratched, lost, or broken.
It is tempting to use old glasses in a pinch, but outdated lenses are not always great for your eyes. At Downtown Vision Care, we can help you figure out if your current glasses are still doing the job or if it is time to update your prescription.
Regular eye exams ensure your vision stays sharp and comfortable, so you are not wearing glasses that are not right for you.
Is It Safe to Wear Old Prescription Glasses?
Sometimes, wearing an old pair of glasses is fine, but only under certain circumstances. For example, if your old prescription has not changed significantly, putting on older glasses might still give you adequate vision for daily activities such as reading or watching TV.
On the other hand, if your prescription, or your vision, has changed since you first got those glasses, then wearing them regularly might not be safe for driving. Improper lenses can strain your eyes and lead to discomfort. Plus, certain eye conditions, such as astigmatism, can become more noticeable with an incorrect prescription.
Signs Your Old Glasses Prescription Is Outdated
If you are not sure whether your old glasses are still doing their job, here are some signs that you are working with an outdated prescription:
- Blurry vision: If objects seem fuzzy or if you have trouble seeing clearly at a distance, your prescription may no longer meet your needs.
- Frequent headaches: Headaches, particularly around your temples or eyes, can be a sign that your glasses are not providing the right level of correction.
- Eye strain or fatigue: Are your eyes feeling unusually tired after using your glasses? This is often a red flag that your glasses are no longer suitable.
- Double vision: Seeing two of everything is not just inconvenient, but is also a likely indicator your lenses are not working properly.
- Excessive squinting: If you are constantly squinting to focus while wearing your old glasses, it is a sign they are not up to date with your current needs.
When to Replace Your Glasses Prescription
How often should you update your prescription? For most people, a good rule of thumb is to have an eye exam every year to help keep your prescription up to date.
Pay attention to how your eyes feel and how well your glasses are working for you. If something seems off, request an appointment with your optometrist.

Can You Use Old Glasses in an Emergency?
In an emergency, old glasses are better than no glasses at all. For instance, if you break your current pair or lose them, relying on your old glasses temporarily is a perfectly practical solution.
Keep in mind that, while these older lenses might help you get by for a few days or weeks, they should not replace an updated prescription. In such cases, you will want to replace your primary glasses as soon as possible.
Tips for Updating Your Glasses Prescription
If your glasses are not up to par anymore, here are a few easy tips to help you get an updated prescription and make the most out of your eyewear:
- Book Regular Eye Exams
Visiting your optometrist regularly ensures any changes in your vision are caught early. It also gives you the chance to try updated lenses before making a purchase.
- Ask for Tinted or Coated Lenses
Need extra comfort for screen use or sunny days? Many updated lenses include options for anti-fatigue, UV protection, or light transitions.
- Use Insurance Benefits Before They Expire
If you have workplace insurance or eye care coverage, make sure you are using those benefits to save on new prescriptions regularly.
- Keep a Backup Pair Handy
Your old glasses can serve as a backup in emergencies, but having a second pair with your current prescription is even better.
- Chat About Lens Features
Your optometrist can recommend progressive lenses, thinner frames, or other add-ons to suit your lifestyle.
