What would taking part in the study involve?

The same measurements that were taken on your child the last time they took part in the study will be repeated in the new study. Additionally, to help us understand how vision may impact on school performance, we would like to compare your child’s Key Stage 2 results with our measurements of their eyes. To do this, we need your permission to ask the school for their Key Stage 2 results. If you don’t want us to have this information, that is fine, your child can still take part in the eye.

For your child

Your child (along with other children) will have their eyes tested at school by an optometrist.

  • We will assess how well your child can see by asking them to read some letters on a chart and will assess whether they might need glasses to help them see better.
  • We will use special instruments to measure the shape and length of your child’s eyes very accurately; these tests are very quick and painless and do not touch the eye. To accurately measure the eyes we will need to put some drops into each eye, which take about 30 minutes to work. Click on the icon for further information on the eye drops used in the study.

  • We will also measure your child’s height, weight and waist measurement.
  • Your child will be asked to complete a short questionnaire on his/her health and lifestyle.

The whole examination will take 60 minutes in all. He/she will be given a special certificate at the end of the examination. Our research team will visit the school in advance to explain study arrangements to the children and to answer any questions.

For you

You will be asked to fill in a short questionnaire on your child’s health and development and on the eye health and circumstances of your family, after your child’s vision has been measured. Click on the icon to see a copy of the parent questionnaire.

What will happen after the study?

We will check the results carefully. If we find that your child needs glasses or needs to update his/her glasses we will write to you advising that your child should visit their optician to have a free eye examination.

We hope very much that your child will be able to take part in the study. All the information from the study will be treated in complete confidence.
