Help our researchers develop a better visual fields test for detection.
We are inviting people aged over 40 years with good vision in one or both eyes (with or without glasses or contact lenses), who don’t have an eye condition, to take part in a study aimed at better ways to detect visual field loss. To be eligible, you must have no direct relatives diagnosed with glaucoma.
As part of this project, people will be invited to take part in some non-invasive experiments - they will look at a computer monitor and press a button each time they see a brief spot of light appear on the screen, anywhere in their side vision. Participants will receive £20 compensation, which includes travel expenses.
If you are interested in taking part, or know someone who might be, you can find more information about the study on our website: Vision research and aged over 40 - Moorfields Eye Hospital
