Sleep and screen time link to myopia - ارتباط نزدیک بینی و بدخوابی

New research from Flinders University indicates people with near-sightedness or myopia are more likely to experience poorer sleep quality than people with normal vision.

The study, led by optometrist Dr Ranjay Chakraborty from the Flinders Caring Futures Institute, indicates that people with short-sightedness have more delayed circadian rhythms and lower production of melatonin, a hormone secreted in the brain and responsible for regulating sleep at night, compared to people with normal vision.

People affected by myopia or short-sightedness are familiar with the frustration of only being able to clearly see objects up close, but not a far distance.

The findings, published in the journal Sleep, show that the participants with myopia take longer to fall asleep, sleep for shorter periods of time at night and are more likely to go to bed later or be ‘night owls’ compared to those with normal sight.
