About the research
This project compared the visual health of different generations of British people for the first time. Measures of visual function, including visual acuity (clarity of vision) and refraction (bending of light through the eye), were harmonised across three longitudinal studies, together with extensive self-reported data on visual function and eye disease.
A harmonised dataset of measures of visual function has been produced, which allows an individual’s visual health to be investigated more accurately over their lifetime, and also enables researchers to compare visual health more effectively across generations. The project team also explored links between gender, social position and visual function.
