What are the symptoms of glaucoma?

Untreated glaucoma slowly but steadily erodes peripheral (side) vision. While many of us are familiar with the symptoms of blurred vision or headaches when our prescription changes, peripheral vision loss is not apparent until a great deal of damage has occurred, essentially leaving tunnel vision. In short, glaucoma has no symptoms … and this means that regular eye examinations are critical in diagnosing glaucoma as early as possible.
