EYESIGHT IS ENDANGERED –
Feb. 21, 2025 – Myopia is caused by having an over elongated eyeball and is a growing problem, with research suggesting about 40% of children and adolescents worldwide could have the condition by 2050. While genetics play a role in who develops myopia, other factors that increase risk include not spending enough time outdoors and focusing on things that are close up for prolonged periods, When the researchers delved deeper they found the risk of myopia rose steeply as daily screen time increased, with 5% greater odds of myopia for one hour a day of exposure compared with no screen use, and 97% higher odds for four hours’ use a day.
Beyond that duration, the researchers added, the odds rose more slowly, while there was no clear association with myopia for screen use below one hour a day, suggesting a potential “safety threshold”.
