Research summary
This study will look at how and why a reduction in vision that is related to a difference in glasses prescription between the right and left eyes can affect 3D vision. This will be done by using 2 different 3D vision tests which measure 2 different aspects of 3D vision. One will test whether these participants can not make out 3D vision at all. Whereas the other test measures whether these participants have trouble making out the finer detail in 3D vision.
These tests have been done in other research using participants who do not have this specific eye problem, but their vision had been blurred using filters on glasses to try and imitate the condition. This sort of research has not been done on children with this eye problem, although it is children who are mostly affected with this problem. For this reason, children between the ages of 4 and 9 seen as patients within the Mid Yorkshire Hospitals NHS Foundation Trust, will be recruited for this study. 26 children with a difference in glasses prescription between the right and left eyes will be used. Another 26 children without this eye problem will be recruited to be in the control group. All participants will be tested in an Orthoptic Clinic room within their standard appointment.
Participants and parents/guardians will be sent an adult and children's Participant Information Sheet to read 1-2 weeks before their appointment. If they are happy to take part, they will sign a consent form when they arrive at their appointment. After which, the participants will be set up to take the 2 3D vision tests. This should take no more than 15 minutes longer than their usual appointment.REC name
