Study summary

The purpose of the study is to quantify the effectiveness of Hoya MiyoSmart IQ (DIMS-TED) spectacle lenses in slowing the rate of myopia progression in university students.

Read the detailed description

MiyoSmart spectacle 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 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.
