Key Takeaways
- Blurry vision, headaches, and eye fatigue are signs your prescription may need updating.
- Most glasses prescriptions stay valid for up to 2 years, but vision can shift sooner.
- Children can often benefit from annual eye exams, while most healthy adults typically need them every 2 years.
- Contact lens prescriptions often expire after 1 year and require a separate fitting.
- A comprehensive eye exam checks visual clarity, eye pressure, and overall eye health.
When you first got your glasses, they made everything come into focus so you could see clearly again. But lately, text looks a little fuzzy, your eyes feel tired by midday, and you find yourself squinting at things that used to be clear. At Northern Lights Eyecare, one of the most common questions we hear is how often you need to update your glasses prescription, and we’re here to help.
Most glasses prescriptions are valid for 2 years, though it may be time to update your glasses if you notice symptoms of eye strain. Visiting us for a comprehensive eye exam can help you update your prescription and provide a clear picture of your overall vision health.
Signs Your Prescription Needs an Update
If your prescription is no longer providing the clear vision you need, your eyes may be giving you clues that they need some extra support. We want you to be able to recognize those clues, so you know it may be time to book an appointment.
Watch for these common signs that your prescription may be outdated:
- Blurry or fuzzy vision even with your glasses on
- Frequent headaches, especially after reading or focusing for a long time
- Constant squinting or difficulty holding focus
Eye Fatigue and Light Sensitivity
If your eyes feel worn out by early afternoon, or bright lights bother you more than usual, those are signals worth paying attention to. Eye fatigue that persists, along with sensitivity to indoor or outdoor light, may indicate a prescription that needs updating. Working harder to see clearly puts real strain on your eyes over time. Digital screen use can make these symptoms feel worse, especially if you spend long hours in front of a computer.

How Often You Should Get an Eye Exam
There’s no single answer for everyone, but there are general guidelines that can help you stay on top of your vision health. Comprehensive eye exams are important because they do more than measure how well you see. They also check for early signs of eye disease, many of which show no symptoms until they’ve already progressed.
Here are some general guidelines to follow, based on age group:
- Children can benefit from annual eye exams to catch changes early and support visual development
- Healthy adults generally need an exam every 1-2 years, or sooner if something shifts
- Seniors may benefit from yearly exams to track changes in eye health
When More Frequent Exams Make Sense
Some situations call for shorter gaps between appointments. If you have an existing eye condition that affects your vision, or if your prescription has changed noticeably over a short period, your eye doctor may recommend more regular check-ins. This can help detect shifts in your vision before they impact your life.
For example, patients managing conditions like diabetes or high blood pressure often need more frequent visits as part of their ongoing care.
How Long a Glasses Prescription Stays Valid
In many cases, glasses prescriptions are valid for up to 2 years. That said, your vision can change before the 2-year mark, especially during periods of rapid change or if you have an underlying condition that affects your eyes. A prescription that felt fine 6 months ago might not be giving you the clarity you need today.
If you feel like something has changed, our team can assess your eyes and help provide the solutions you need.
Glasses vs. Contact Lens Prescriptions
Contact lens prescriptions are a separate matter. They typically expire after 1 year instead of 2. If you wear both glasses and contacts, it’s worth knowing that a contact lens fitting is its own appointment, separate from a regular eye exam, because the fit and measurements for contact lenses are different.
What Happens at an Eye Exam?
We want your experience to be straightforward and simple. Our eye doctor can test your visual acuity to measure how clearly you’re seeing at various distances. We may also check your eye pressure along with some other tests as part of a broader assessment of your overall eye health. If your vision has shifted, we’ll issue a new prescription on the spot.
What to Bring and Expect
Bring your current glasses to the appointment so our eye doctor can compare them to your updated measurements. It also helps to jot down any symptoms or vision concerns beforehand, even ones you may think are small, like occasional blurring or light sensitivity. The more detail you can share, the more our team can tailor your care.
Eye Exams for the Whole Family
Whether you’re booking for a family member or coming in yourself for a routine check, at Northern Lights Eyecare, we offer care for every age and stage. Early eye exams for children can catch vision problems that might otherwise affect learning or development. For adult and senior patients, we provide extra attention to how their vision changes over time.
If your needs go beyond a new prescription, we’re ready for that too. Your eye exam can be the starting point for a lot more than just a new pair of glasses. Here are some of the services we provide alongside eye exams:
- Dry eye therapy for when eye drops just aren’t enough
- Myopia control for growing kids with stronger prescriptions each year
- MacuMira treatment for patients managing age-related macular degeneration
- Laser eye consultation in Prince Albert for those exploring surgical options
