I’ve been reading your comments and everyone wants to know if the blue light exposure they get from their digital devices is putting them at risk for eye damage. I get it. We’re all working from home on our computers during the day and checking our phones constantly. That surely must be doing something to our vision, right? Let’s break down the truth behind all-things blue light, such as digital eye strain, the 20/20/20 rule, and macular degeneration.
I LOVE reading your comments and take your suggestions seriously. If there’s a subject you want me to discuss or something you’d like for me to react to, leave a comment down below. Many of my videos have been born out of suggestions directly from you, so don’t hold back!

  • If I'm completely honest I don't think blue light is the only thing that is concerning about using electronics at night before bed. for me I always have my blue light off but I still have a hard time putting my phone down at night, but I think that the blue light isn't what's causing me to stay awake, it's the use of my brain. Watching UZworld and tik tok and scrolling through Facebook or any social media, all of that is requiring me to have a lot of thought which in turn keeps me awake. My mom likes to read before she goes to sleep but she only reads books that she's read before to go to sleep, the reason being is if she picks up a new book that she's interested in and is invested in it's going to keep her awake because she doesn't know what happens next and the suspense can keep her awake.

  • Dr. Mike, can you respond to anti-vaccine videos by UZworldr Paul Thomas MD. He’s a pediatrician who I tuned into to learn more about common childhood ailments and was greatly disappointed by his approach to vaccines. He’s “vaccine friendly” meaning friendly to delaying or skipping, and has written a book about his vaccine views. You’ve made some amazing vaccine videos and everyone should be primed to receive the COVID-19 vaccine next year. He’s said kids in schools shouldn’t have to wear masks and that masks don’t do much anyway. It’s doctors like him who worry me.

  • Dr Mike - speaking of cell phones, is it a bad idea to sleep with your phone near you body or head? Such as effecting memory or sleeping problems or other health issues from radiation. I ask because I’ve just noticed if anyone (myself included) has cell phones under their pillows or near their face while falling asleep we sleep worse than if it’s away. I’m taking into account that blue light and FOMO are causes but can cell phone projected radiation cause this as well? I like to educate myself of bettering my interaction with electronics and focus (and overall health in learning to NOT be on my phone for everything, as well as TVs and such) and I’d appreciate your thoughts on it. Stay happy and healthy!

  • Light pollution is such an easy type of pollution to fix. Using lights of 3000K temperature or lower and those of more modest brightnesses and all of it pointed where only it's needed. Not only you make it safer at night by not glaring a lot and improving the quality of sleep and also preventing the death of billions of migrating birds that die by exhaustion due to being driven off path and into windows. And the lovely night sky is within the reach of city dwellers from the comfort of home.

  • question: been sleeping every night with a virtual reality headset on for the past year... personally i find i fall asleep faster with it on. the head strap is on loosely and the display is dimmed usually an hour or two before i try to sleep. the display also turns off after 30 minutes... many people have been telling me that wearing a screen strapped to my face while i sleep is extremely unhealthy. just curious on what a doctor thinks about it, should i stop? (p.s i have no issues with eye strain, dry eyes or head aches and i'm 25)

  • I accidentally looked at the sun/moon eclipse once when I was younger, now I lost a very small part of Central vision in my left eye, not that big deal, It's very annoying only If I try to read small font with closed right eye, and the damaged part of my vision is not black, it's like I messed up with a Photoshop tool in a particular point, if staring a grid in the distance with only that eye I will see the iron bars kind of distorted, the eye doctor said there's nothing to do about that

  • Why are you promoting a weight loss program like Noom? You must know there is no medical evidence that weight loss is helpful for curing diseases. I'm really disappointed that someone who says they say the "Truth" is promoting a lie. Please don't sell out to a fat-phobic and body shaming culture. Super depressing, man.

  • Is this whole video sponsored content from MVMT? Any so called blue blocking glasses that have clear lenses like the MVMT glasses are most likely complete BS. If the glasses are clear then they are not removing much blue light at all. That's basic physics. If you remove a decent portion of the blue light then the glasses would appear yellow and if you remove most of the blue light then the glasses would be orange. If you actually read published papers on blue blocking glasses then they are most often using very orange glasses that remove around 80% of the blue light. Lenses that appear clear most likely only remove 10-15% of the blue light which is likely insignificant to produce the results claimed. And when doing sponsored content, please give us the courtesy of telling us it's an add.
