COS Urges Canadians to Prioritize Eye Exams During Glaucoma Awareness Month

Tuesday, January 6 2026 | 14 h 01 min | News

As January marks Glaucoma Awareness Month, the Canadian Ophthalmological Society (COS) is reminding Canadians of the critical importance of regular comprehensive eye exams for the early detection of glaucoma, a leading cause of irreversible vision loss.

Often referred to as the “silent thief of sight,” glaucoma typically develops without pain or noticeable symptoms. By the time changes in vision become apparent, permanent damage to the optic nerve may already have occurred. While treatments can slow or manage disease progression, vision loss caused by glaucoma cannot be reversed.

According to COS, more than 800,000 people in Canada are affected by glaucoma, and many are unaware they have the condition. Risk factors include advancing age, a family history of glaucoma, certain medical conditions such as diabetes, and higher prevalence among individuals of African, Asian, or Hispanic descent.

“Glaucoma is a lifelong condition, but when we detect it early, we can slow its progression and help patients preserve their vision,” said Dr. Hady Saheb, glaucoma and anterior segment surgeon at McGill University. “Because glaucoma rarely causes symptoms in its early stages, regular comprehensive eye exams are essential.”

COS encourages adults, particularly those over the age of 40 or with known risk factors, to speak with their eye care professional about appropriate screening intervals. Comprehensive eye exams typically include measurement of intraocular pressure and evaluation of the optic nerve, both key components in identifying glaucoma early.

“Regular eye exams are one of the simplest and most effective ways to protect your sight,” Dr. Saheb added. “Glaucoma is manageable, and early detection truly matters.”

Throughout Glaucoma Awareness Month, COS will share evidence-based information and educational resources aimed at improving public awareness and encouraging proactive eye health care.
