Study Overview
Brief Summary
The purpose of the study is to quantify the effectiveness of Coopervision MiSight contact lenses in slowing the rate of myopia progression in university students.
Detailed Description
MiSight contact lenses have been shown to be a safe and effective way of managing myopia progression in children aged 8-12 years. However, myopic progression is not limited to children of this age group and MiSight lenses have also been shown to be effective in older children aged 11-16 years. There is evidence that progression also occurs in university students. The researchers are therefore investigating the effectiveness of this intervention in a group of UK-based University students.

- •Have read the patient information sheet and be happy to sign the consent forms
- •Be willing to adhere to the visit schedule and wearing times described in this protocol
- •Agree to lens wearing times of at least 10 hours per day, 6 days per week
- •Agree to accept either the control or test lens as assigned by the randomisation
