People with myopia have delayed circadian rhythms and lower production of melatonin compared to people with normal vision and are more likely to experience poorer sleep quality, a Flinders University study found.
In the study, conducted in collaboration with the Flinders University Sleep Institute, the circadian timing and production of melatonin was measured in myopic and non-myopic university students in their twenties, using saliva and urine samples.
“These findings provide important evidence that optimal sleep and circadian rhythms are not only essential for general health, but also for good vision,” said study lead optometrist Dr Ranjay Chakraborty from Flinders Caring Futures Institute.
