I think blue light interferes with your sleeping pattern and that’s why.”\u003cbr/\u003e\u003cbr/\u003e “More than two billion people worldwide use a smartphone. The individual average usage is estimated to be between four to five hours a day.\u003cbr/\u003e\u003cbr/\u003e London smartphone user Marcela Montes says she has concerns about her vision: “For my eyes I will worry because sometimes at night when I use [my smartphone] before I sleep, when I close the cellphone and put it off, I can feel like in my eyes [there are] some black points sometimes.”\u003cbr/\u003e\u003cbr/\u003e The New England Journal of Medicine\u0026 has reported the separate cases of two women who experienced “temporary blindness” for months.\u003cbr/\u003e\u003cbr/\u003e Although most people look at screens with both eyes, people frequently use smartphones while lying down, where one eye can be inadvertently covered or out of focus.\u003cbr/\u003e\u003cbr/\u003e According to Dr Gordon Plant, consultant neurologist at the \u003cbr/\u003eNational Hospital of Neurology: “It will take several minutes before the right eye can see as well as the left eye, the opposite is true of course if they’re lying on their right side. \u003cbr/\u003e\u003cbr/\u003e “So what worries them is that they think the problem is that they can’t see with the eye that’s been exposed to the light and if they’d been viewing the phone with both eyes, both eyes would be the same and they wouldn’t think anything of it.”\u003cbr/\u003e\u003cbr/\u003e After the women have been complaining of bouts of temporary vision loss they underwent various medical investigations, including MRI scans and heart tests. At first no cause could be found.\u003cbr/\u003e\u003cbr/\u003e “Transient monocular visual loss, so the temporary loss of vision in one eye, is a very, very important symptom, because it can be the warning of a stroke,” Dr Park adds. \u003cbr/\u003e\u003cbr/\u003e “And it’s one of the commonest reasons that a patients coming through Moorfields [Eye Hospital] casualty are referred to a stroke unit because they’ve had transient loss of vision in one eye and although, of course it’s much more common in older people, even young people can have strokes and can have a risk of stroke”\u003cbr/\u003e\u003cbr/\u003e Symptoms of temporary smartphone blindness are very similar to a more serious problem such as a stroke. There lies the problem as this can cause a wrong diagnosis from doctors, the neurologist warns.\u003cbr/\u003e\u003cbr/\u003e Dr Plant continues: “A few years ago these patients would be referred first to specialist clinics. \u003cbr/\u003e\u003cbr/\u003e “But now because of the stroke pathways and hyper-acute treatment of stroke they’ll be referred automatically to a stroke unit where they’re seen by stroke physicians who aren’t necessarily au fait (familiar) with ophthalmic disorders, and they’ll just be processed automatically, have MRIs and CTs and ultrasounds and all the rest of it.”\u003cbr/\u003e\u003cbr/\u003e So watching tiny screens may harm your vision, and affect your sleep. The solution – take a break every 20 minutes or read a book in bed.\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex justify-between'\u003e\n\u003cbutton aria-expanded='false' aria-label='Read more description' class='rp-full-description' type='button'\u003e\n\u003ci class='fai fa-solid fa-align-left'\u003e\u003c/i\u003e\n\u003cspan id='read_more'\u003eRead More\u003c/span\u003e\n\u003c/button\u003e\n\u003cdiv class='rp-report'\u003e\n\u003c/div\u003e\n\u003c/div\u003e\n\u003cdiv aria-labelledby='resource-details-heading' class='rp-info-section'\u003e\n\u003ch2 class='title' id='resource-details-heading'\u003eResource Details\u003c/h2\u003e\n\u003cdiv class='rp-resource-details clearfix'\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\u003cdt\u003eCurator Rating\u003c/dt\u003e\n\u003cdd\u003e\u003cspan class=\"star-rating\" aria-label=\" out of 5 stars\" role=\"img\"\u003e\u003ci class=\"fa-regular fa-star text-action\" aria-hidden=\"true\"\u003e\u003c/i\u003e\u003ci class=\"fa-regular fa-star text-action\" aria-hidden=\"true\"\u003e\u003c/i\u003e\u003ci class=\"fa-regular fa-star text-action\" aria-hidden=\"true\"\u003e\u003c/i\u003e\u003ci class=\"fa-regular fa-star text-action\" aria-hidden=\"true\"\u003e\u003c/i\u003e\u003ci class=\"fa-regular fa-star text-action\" aria-hidden=\"true\"\u003e\u003c/i\u003e\u003c/span\u003e\u003c/dd\u003e\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\u003cdt class=\"educator-rating-title\"\u003eEducator Rating\u003c/dt\u003e\u003cdd\u003e\u003cdiv class=\"educator-rating-details\" data-path=\"/educator_ratings/rrp_data?resourceable_id=91033770\u0026amp;resourceable_type=Boclips%3A%3AVideoMetadata\"\u003e\u003cspan class=\"not-yet-rated\"\u003eNot yet Rated\u003c/span\u003e\u003c/div\u003e\u003c/dd\u003e\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\u003cdt\u003eMedia Length\u003c/dt\u003e\n\u003cdd\u003e3:55\u003c/dd\u003e\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\u003cdt\u003eGrade\u003c/dt\u003e\u003cdd title=\"Grade\"\u003eAll Grades\u003c/dd\u003e\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\u003cdt\u003eSource:\u003c/dt\u003e\n\u003cdiv class='preview-source' data-animation='true' data-boundary='.rp-info' data-container='.rp-resource-details' data-html='false' data-title='Get the latest science and hi-tech news across an in-depth look at scientific developments from Europe and the World' data-trigger='hover focus'\u003e\n\u003cspan\u003eEuronews SciTech\u003c/span\u003e\n\u003ci aria-hidden='true' class='fa-solid fa-circle-info channel-tooltip-icon' id='channel-tooltip'\u003e\u003c/i\u003e\n\u003c/div\u003e\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\u003cdt\u003eDate\u003c/dt\u003e\n\u003cdd\u003e2016\u003c/dd\u003e\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\u003ci aria-hidden='true' class='fai fa-solid fa-language'\u003e\u003c/i\u003e\n\u003cdt\u003eLanguage\u003c/dt\u003e\u003cdd\u003eEnglish\u003c/dd\u003e\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003cdiv class='detail'\u003e\n\u003cdl\u003e\n\u003cdt\u003eUsage Permissions\u003c/dt\u003e\u003cdd\u003eFine Print: Educational Use\u003c/dd\u003e\n\u003c/dl\u003e\n\u003c/div\u003e\n\u003c/div\u003e\n\u003c/div\u003e\n\u003cdiv aria-labelledby='additional-materials-heading' class='rp-info-section'\u003e\n\u003ch2 class='title' id='additional-materials-heading'\u003eAdditional Materials\u003c/h2\u003e\n\u003cdiv class='additional-material'\u003e\n\u003ci aria-hidden='true' class='fai fa-solid fa-lock'\u003e\u003c/i\u003e\n\u003ca class=\"text-muted\" title=\"Video Transcript\" data-html=\"true\" data-placement=\"bottom\" data-trigger=\"click\" data-content=\"\u003cdiv class=\u0026quot;text-center py-2\u0026quot;\u003e\u003ca class=\u0026quot;bold\u0026quot;
