While glaucoma does not normally cause symptoms early on, once the disease develops it can begin to elicit signs from the body such as:
• Intense eye pain
• Nausea
• Vomiting
• A red eye
• Headache
• Tenderness around the eyes
• Seeing rings around lights
• Blurred vision.

On the development of symptoms, the NHS added: “It tends to develop slowly over many years and affects the edges of your vision (peripheral vision) first. For this reason, many people do not realise they have glaucoma, and it’s often only picked up during a routine eye test.

“If you do notice any symptoms, they might include blurred vision, or seeing rainbow-coloured circles around bright lights.”

Furthermore, just like other conditions, glaucoma can have a range of causes which lead to or increase someone’s risk of the condition. This includes age, ethnicity, family history, and other medication conditions.
