High blood pressure — also known as hypertension — affects one in three British adults, with around 14.4million thought to have it.
If left untreated, it can lead to an increased risk of heart disease and stroke.
The condition causes blurred vision in a number of ways.
It can cause damage to the small blood vessels that supply oxygen to the retina — the light-sensitive nerve tissue at the back of your eyes.
The American Heart Association said: “A lack of blood flow to the retina leads to blurred vision or the complete loss of sight.
“People with diabetes and high blood pressure are at an even greater risk for developing this condition.
“Managing blood pressure is also the only way to treat hypertensive retinopathy.”
High blood pressure can also cause a build-up of fluid under the retina, impairing your vision.
Blocked blood flow can also damage the optic nerve, which sends messages from your eyes to your brain.
The AHA said: “It can kill nerve cells in your eyes, which may cause temporary or permanent vision loss.”
People with hypertension are also more at risk of stroke, which can cause vision problems.
Strokes can damage the optic nerve, as well as affecting the part of the brain linked to processing images.
If you are worried about your blood pressure, you can have it checked by your GP or pharmacist.
High blood pressure is considered to be from 140/90mmHg, or 150/90mmHg if you’re over the age of 80.
You can reduce your chances of hypertension by avoiding smoking, large amounts of alcohol and salty foods, while also exercising at least 150 minutes a week.
