People should make regular visits to an ophthalmologist in order to determine if they have glaucoma, it has been suggested.
Valerie Greatorex, senior Sightline operator at the International Glaucoma Association, said that those over the age of 40 should aim to get their eyes tested every two years.
Ms Greatorex pointed out that this is the best way to determine if people have the condition or not.
She said that the three tests carried out by the ophthalmologist will "alert the ophthalmologist to [whether] you need to refer a person to their GP and then on to the hospital".
Those who wish to improve their vision could benefit from
orthokeratology.
Ortho k lenses are special contacts that are worn only at night and help to reshape the cornea, which restores vision on a temporary basis.
During the day, people who benefit from
orthokeratology do not need to rely on any eyewear, such as glasses or contact lenses.
