A ‘slumber party’ to investigate the impact of different types of light on myopia

A US experiment will involve children sleeping over in a lab before being periodically exposed to red and blue lights

University of Houston scientists have received a $1.8m (£1.48m) research grant to investigate why increasing numbers of children internationally are developing myopia.

The project will assess whether exposure to different types of light might play a role in preventing short-sightedness.

As part of the research, study participants between the ages of seven and 14 will sleep over at a lab with different coloured lights turned on intermittently.

Researchers will examine the choroid in children to gain insight into how circadian rhythm, light exposure and defocus from lenses that blur images change choroidal thickness.

Study participants use wearable technology to record how much light exposure each child is getting.

Lisa Ostrin, from the University of Houston, shared that the research will fill “a critical void” in the understanding of visual input in choroidal modulation in children.

“The research will contribute to the development of targeted treatment options to prevent myopia and slow progression.”
