TLDRDr. Wagner, an emergency room doctor, explains the effects of blue light exposure from screens, highlighting its impact on eye strain, headaches, and sleep disruption. Blue light is naturally present from sunlight but excessive exposure, especially at night, can disrupt melatonin production and overall hormone balance, affecting health. While blue light glasses have inconclusive benefits according to the American Academy of Ophthalmology, various lifestyle adjustments can mitigate eye strain, such as taking screen breaks, using red light for night lighting, and applying screen filters. For ongoing issues, it's advisable to consult a healthcare professional.

    I denne video diskuterer Dr. Jordan Wagner konsekvenserne af blåt lys for sundheden, især dem der arbejder hjemmefra med digitale skærme. Han forklare, hvordan blåt lys kan forårsage øjenbelastning, hovedpine og forstyrrelser i søvncyklusser ved at påvirke melatoninproduktionen i kroppen. Derudover nævner han, at mens blåt lysbriller ikke nødvendigvis anbefales som en løsning, er der alternative metoder såsom at tage pauser fra skærme, bruge rødt lys om natten og aktivere nattilstand på enheder for at mindske eksponeringen. Hvis symptomerne vedvarer, opfordrer han seerne til at konsultere en øjenlæge.

    Hey everyone!
  • 00:00:35
    I'm Dr. Jordan Wagner.
  • 00:00:37
    I'm an emergency room doctor who treats everything  from COVID to gunshot wounds, burns, you name it.
  • 00:00:43
    I've created this video series to help  answer some of your medical questions
  • 00:00:47
    and the questions that I get  from patients each and every day
  • 00:00:50
    If you find this video helpful  please do me a favor and subscribe.

    Let's first understand the science  of what blue light actually is.
  • 00:00:57
    Blue light is a type of visible light on the  light spectrum and it has a short wavelength.
  • 00:01:03
    Due to the short-wavelength blue light rays  contain more energy than many other light types.
  • 00:01:08
    In fact, blue light isn't just  produced by artificial sources only.
  • 00:01:12
    We actually see blue light naturally  every time we look up at the sky.
  • 00:01:17
    But here's the deal, for thousands of years humans  were exposed to blue light only during the hours
  • 00:01:22
    that the sun was up and our brains were trained  to interpret blue light as a cue to be awake,
  • 00:01:28
    alert, energetic, and ready for action.
  • 00:01:30
    Being and feeling alert is good but  too much exposure to blue light on
  • 00:01:34
    the other hand can cause adverse effects as well.
  • 00:01:37
    For starters, if you’re exposed to too much blue  light during the day, your eyes can grow fatigued.
  • 00:01:43
    But you may say to me doc, my eyes  are tired but my body is wide awake.
  • 00:01:47
    What the heck is happening?
  • 00:01:48
    Well, blue light may be disrupting your health  in other ways, such as your sleep patterns.
  • 00:01:53
    The way this works is, the  blue light sends signals to
  • 00:01:56
    your brain that can affect your  body’s production of melatonin.
  • 00:02:00
    This can make it hard to fall asleep and stay  asleep after using your devices at night.
  • 00:02:05
    And beyond sleep quality, melatonin  disruption throws off the entire
  • 00:02:09
    hormone balance in your body which in turn  affects your overall health and wellbeing.
  • 00:02:14
    Poor sleep quality can also change  the way that your body feels stress.
  • 00:02:18
    When you aren’t getting REM sleep  your mind isn’t able to fully relax.
  • 00:02:23
    So how do you reduce blue  light effects in your life?
  • 00:02:26
    We've seen them everywhere, those trendy blue  light glasses, but do they actually work?
  • 00:02:31
    Right now, the evidence for blue  light glasses as a preventive
  • 00:02:35
    measure for reducing blue light exposure is mixed.
  • 00:02:38
    The American Academy of Ophthalmology  doesn’t currently recommend special
  • 00:02:42
    blue-light-filtering glasses for  use when you work with computers.
  • 00:02:45
    This may change in the future.
  • 00:02:47
    There's a study that is currently underway to more
  • 00:02:50
    comprehensively examine whether blue  light glasses have definitive benefits.
  • 00:02:54
    A 2017 study from Ophthalmic and Physiological
  • 00:02:58
    Optics found that three clinical  trials had poor evidence to support
  • 00:03:02
    the use of blue-light-blocking glasses to  preserve eye health and prevent dry eye.
  • 00:03:07
    However, there are several lifestyle  tips for reducing blue light exposure.
  • 00:03:11
    You don’t have to purchase blue light glasses  to reduce your exposure to blue light.
  • 00:03:15
    Number one, protect your eyes  from eye strain and fatigue
  • 00:03:19
    by adopting some eye-health-friendly habits,
  • 00:03:21
    including taking eye breaks from your screens  or dim the lights in your home or workspace.
  • 00:03:26
    Number two, you could even consider
  • 00:03:28
    using red light as opposed to an LED  bulb as a nightlight in your bedroom.
  • 00:03:33
    Red light is less likely to disrupt your circadian  rhythm because red wavelengths are much shorter.
  • 00:03:39
    Number three, try a filter on your screen or  I highly recommend switching your device to
  • 00:03:44
    night mode for certain hours of the day.
  • 00:03:46
    These filter the amount of blue  light your screens give off.
  • 00:03:49
    If you’ve tried some of these tips,  but you’re not experiencing the type
  • 00:03:53
    of relief you had hoped for, well then it  might be time to speak with your doctor.
  • 00:03:56
    Blue light exposure may already  be causing you to have continued
  • 00:04:00
    symptoms like eyestrain and dry eye.
  • 00:04:02
    As far as blue light glasses go, the definitive  verdict is still out on their ability to
  • 00:04:06
    substantially reduce your exposure to blue  light and the associated symptoms of exposure.
  • 00:04:10
    But limiting blue-light exposure,
  • 00:04:12
    adopting habits to take better care  of your eyes, and taking breaks from
  • 00:04:16
    your screens can all help you avoid dry eyes  and eyestrain caused by blue light exposure.
  • 00:04:21
    If these symptoms don’t resolve with lifestyle  changes and self-care strategies within a short
  • 00:04:26
    span of time, I highly recommend you speak with an  eye doctor about them, sooner rather than later.
  • 00:04:32
    Alright, that’s been a blue light  breakdown, with me Dr. Wagner.
