Late in 2024 , a comprehensive study publish in the British Journal of Opthalmology claimed that “ the global prevalence of childhood myopia is substantial . ” base on the current trends , it predicted that by 2050 , the number of children and untried multitude with nigh - seeing issues will stand roughly at 740 million .
The trends are concerning , but at the same , the scientific community is also puzzled about the role of increasing screen photo and how it affects our eye health . Well , it seems there is a relationship between daily covert clip and the prevalence of myopic vision in users across the world .
As per a meta analysis published in theJAMA journal , there is a correlation between increasing screen prison term on a per - hour basis and the risks of myopia going up by 21 % in users of smart gadget such as sound and large - screen electronics .
Rising screen time ups the odds of myopia
The theme , which analyzed over 45 studies covering over 0.3 million subjects , observe that there is a noteworthy dose - reaction link between a individual ’s everyday projection screen clip — especially following a 1 - hour increase — and their betting odds of develop nearsightedness . “ nearsightedness risk increased importantly from 1 to 4 hr of screen time and then rose more gradually thereafter , ” claim the expert behind the study .
Notably , the risks of shortsightedness growth significantly when we look at the flux upshot of screen metre from multiple twist ( such as mobiles , computers , and tv ) compare to display exposure from only a single class of devices .
Moreover , “ a significant association was observed ” between nearsightedness risk of infection and rise screen clock time in all age group , including 2 to 7 years , 8 to 18 geezerhood , and 19 twelvemonth and older . Notably , the researchers found that the odds of near - sightedness increase if the daily screen time was more than 1 hour , but it slow down when the numbers rifle beyond four hours per day .
Moreover , a certain kind of safety doorway was celebrate if the daily screen time falls under the one - hr bracket . There are , however , a few cautionary vista relate with the latest study , particularly when it come to decreasing the jeopardy of myopia .
“ Simplyreducing screen timein party favour of traditional skinny - vision activities may not be an effective prevention strategy , ” the experts say . Instead , they recommend a hybrid coming where near - vision screen clip numbers are trim down and the amount of time spent outdoor is increase .
Another study published in theJournal of Opthalmologyin 2022 also highlighted the rise in nearsightedness with a correlativity based on exposure to sieve , specially for nigh vision scenario . It is also deserving nothing that myopia is not entirely triggered by star at a blind for long time .
It is associated with lifestyle , environmental , and genetical factors , as well . Notably , another inquiry publish earlier in 2025 claimed thatreducing screen time can yield skillful genial health results than anti - depressants .
So , how can a person ensure myopia peril tie to daily screen usage ? Scientific research suggest spending more time out of doors can cut the risk of myopia onset , but it is not conclusive . Solutions such as bifocal spectacle lens , EDOF liaison lens system , and orthokeratology lenses are connect with moderate reduction in the advancement of myopic vision .
refractile surgery is another choice , but the most bright strategy seems to be atropine solution for myopia dominance with the highest efficacy . The secure approach , however , is to confer with with a certified health care professional and recover the apt resolution for sight - related issues .
