What is involved?


Children who take part in our research study will have their eyes tested in school during the school day. We have special eye tests for children who can't read, talk, point or who have very limited attention. This means we can include children across all ages and abilities.    


We will also spend some time with each child to see how they use their eyes and participate in the classroom.


Afterwards we will provide parents, teachers and other professionals involved in the care of the child with a written report describing our findings. We hope that this will provide information on how well each child can see, and how they can make the best use of their vision both at home and in the classroom.


Two to five months after we first test each child, we will repeat all of our tests to see if any of the measurements have changed. 



What does the Eye Examination involve?


Vision - We will assess how much each child can see. For some children this only involves looking at pictures while we observe their eye movements. Other children may match or name pictures or letters. 


Eye movements - This will involve identifying if the eyes squint or turn in, and how the eyes move in each direction. 


3D vision - Where possible and appropriate each child’s 3D depth perception will be tested using a simple 3D task.


Visual perception - We will test each child’s ability to arrange simple 3D shapes to a given pattern.


Glasses prescription - Each child’s need for glasses will be measured. This will require drops being put into the eyes as this is the best, most accurate way of assessing the need for glasses in children. These drops are used routinely by eye care professionals to test children’s eyes. After inserting the drops we will shine a light into the eye to find out if there is a significant need for glasses.  


Eye health - the health of each child’s eyes will be examined by shining a light into the eyes for a short period of time.
