Eye health specialists are sounding the alarm over what is being described as a “silent blindness epidemic,” following a worrying rise in glaucoma cases across Britain — one of the leading causes of permanent vision loss worldwide.

Recent figures show that more than one million people over the age of 40 are living with glaucoma, while experts believe the real number is significantly higher, as many cases remain undetected because early stages often show no symptoms.

Glaucoma develops when pressure builds up inside the eye, damaging the optic nerve that carries visual information to the brain. In many patients, vision loss appears only after irreversible damage has already occurred.

Researchers predict that cases will surge in the coming decades as the population ages, with the number of affected individuals expected to exceed 1.6 million by 2060 — nearly a 60% increase from current levels.

Specialists stress that much of the vision impairment caused by glaucoma could be avoided with earlier diagnosis, noting that delayed detection removes the chance to slow the disease before severe damage develops.

Risk increases sharply with age, especially among people over 85, and certain ethnic groups face higher vulnerability, placing growing pressure on future healthcare systems.

Although there is no permanent cure for glaucoma, early treatment using eye drops, laser therapy, or surgery can slow optic nerve damage and preserve remaining vision.

Experts emphasize that expanding routine eye screening and public awareness is the most effective way to confront this silent epidemic before it turns into a widespread health crisis.
