Eye health is often treated as separate from the rest of the body, yet the eyes can reveal far more than changes in vision alone. Subtle shifts in ocular health may be early indicators of broader physical conditions, from cardiovascular disease to diabetes and neurological disorders. Because of this close connection, regular eye exams are not just about updating a prescription, they can be a vital component of preventive healthcare.
Glaucoma, for instance, is one of the leading causes of irreversible vision loss in Canada, yet it often develops without noticeable symptoms. Many people don’t realize anything is wrong until their vision has already been affected. That’s one of the many reasons why why early detection and regular eye exams remain such an important public health issue.
To learn more about how eye health ties to overall health, we connected with Naomi Barberfrom, Clinical Services Director for Specsavers.
How can eye health be an indicator of general health, and why is it important to have regular eye exams for overall health?
Many people are surprised to learn that an eye exam can reveal much more than changes in your vision or whether you need glasses. A comprehensive eye exam can help optometrists detect early signs of many conditions, including diabetes, high blood pressure and high cholesterol, sometimes before symptoms appear elsewhere. The Specsavers Canada Eyecare Report 2025 highlights that more than eight million Canadians are at risk of eye threatening conditions, some of which may be connected to systemic health. In fact, more than 90% of vision loss is preventable when eye diseases are detected early through comprehensive exams. A routine eye exam is an important step in protecting both your sight and your overall health.
What do we have to be aware of regarding our eye health as we age?
Age increases the risk of eye diseases. As we age our risk of sight threatening conditions increases greatly. However it is early care and prevention that makes the biggest difference to how well you will see when you’re older.
Changes can be gradual. Many people assume declining vision is “just aging,” but it can be a sign of something more serious.
Routine eye exams matter. CAO guidelines recommend adults get an eye exam every two years, with annual exams for children and seniors. If you have certain medical conditions, your optometrist may recommend more frequent exams.
OCT imaging is important at all ages. Optical coherence tomography (OCT) are 3D scans help optometrists to spot any abnormalities and identify eye diseases, such as age‑related macular degeneration, glaucoma and diabetic eye disease, in their early stages. This is particularly important if you have risk factors for eye conditions, or a history of eye disease in your family, as it can help your optometrist monitor your eye health over time.
Healthy habits are vital. UV protection, managing chronic conditions, maintaining a healthy lifestyle and having regular eye exams play an important role to support long‑term eye health.
What do people need to know Glaucoma?
If there’s one thing I always tell people about glaucoma, it’s that you can’t rely on symptoms. Glaucoma is often called the “silent thief of sight” because it can develop gradually, without pain or obvious warning signs. The Specsavers Canada Eyecare Report 2025 found that 42% of Canadians believe they would know if something was wrong with their eyes, and 38% say they would only seek care if their vision got worse, yet glaucoma typically progresses long before symptoms are noticeable. By the time someone sees changes in their vision, there may already be permanent damage.
The good news is that glaucoma can be managed if it’s caught early. That’s why regular, comprehensive eye exams are so important. During an exam, optometrists check the optic nerve, measure eye pressure, and use imaging technology like optical coherence tomography (OCT), which can help detect damage before you notice changes to your vision. Without this kind of testing, early glaucoma can be missed.
What makes Specsavers special when it comes to not just eyewear, but eye health?
At Specsavers, our purpose is to change lives through better sight. While many people know us for eyewear, we’re equally focused on delivering accessible, high‑quality care in every community we serve. When Doug and Mary Perkins started Specsavers back in 1984, they wanted to ensure that access to quality and affordable eyecare was available to whoever needed it, whenever they needed it. Since then, everything we’ve done is driven with that same purpose.
Specsavers locations are locally owned and operated, which means our teams are part of the communities they support. We believe protecting long-term vision through early detection and preventive care is essential. That’s why Specsavers equips their locations with OCT devices so that it can be included as part of comprehensive eye exams provided by independent optometrists.
What makes Specsavers different is our commitment to combining clinical technology, professional expertise and local community ownership to make eye health accessible and more affordable.
I recently went into my nearest Specsavers location for a long overdue eye exam. An appointment with Specsavers goes beyond the usual eye chart and frame try on session (though those experiences are included!) As Naomi mentioned, their locations are equipped with top of the line eye care technology, built to help optometrists to conduct comprehensive eye exams and for optimal eye health outcomes.
The experience really opened my eyes to the importance that eye health plays in the bigger health picture. After learning that it’s possible to spot early signs of conditions linked to overall health, from high cholesterol to diabetes, I felt even better about getting that check up. And even better about the cute new glasses I picked up, complete with Progressives lenses to cover all my vision needs, up close and far away.
As I get older, looking after my health becomes has become a higher priority than it was in my younger days. And eye health is a fundamental aspect of overall well-being. It’s not just about seeing things clearly; it’s about living my best life. Get that eye exam today and stay clear-sighted and healthy.
