Eye Health Question of the Day: Do you wear Blue Blight Blocking Glasses? After hearing the science presented, do you think blue light damages the retina?

[DoctorEyeHealth]

HAHAHA Just noticed the camera lines were still on....sorry about that. Well...lesson learned. 😁🤣

[cyndigarcia]

Dr. Allen, If you aren't doing any live professional, Continuing Medical Education (CME) presentations for medical providers, you definitely need to consider doing so. You're an excellent, knowledgable physician speaker!

I use blue light-blocking clip-ons all day at work. I work in IT, and using them have made a big difference in eye fatigue and headaches.

[erikafatimahdonque]

What a good lectures about blue light Doc. Also about sun rays exposure. Indeed, it is debatable whether blue light alone could damage your eyes or sun rays exposure alone could, it is also debatable. But unfortunately speaking from experience, if both are combine, eyesight will really be affected and defected. That's why moderation is important. Thanks.

[Deklectic]

Wow this was very informative... Whats cool is that alot of phones come with a Blue Light Filter you can turn on which I tend to use at night if I watching a movie or show before bed.. OMG it makes such a difference in me being able to fall asleep vs it being off..

[Laurentiius]

When I heard blue blockers were available, I went to the optician and had a couple pair of plain lenses custom made, with AR, UV 400 protection and blue light blockers. Then I heard that computer glasses should have a small magnification. I asked my opthamologist he said Okay So, I requested two additional pair made like readers with 1.50x They told me that I need a Rx if I wanted readers made. So, I asked the optometrist and he gave me an Rx and I had two more pairs made with the same specifications for computer use. Then I heard you say the magnification should be slightly off to decrease eye fatigue. I'm too exhausted dealing with the bureaucracy. These will have to do for now! Thanks, for your informative and up to date, videos!

[reshambains]

I installed blue light filter app on my Android phone after watching this. Thanks!

I bought an BenQ GW2480 Monitor (24") 1080p. It's an IPS Display which means no eye fatigue for finding the sweet spot on Screen sharpness (almost all angles have a sharp Picture) which is one of the most important improvements over traditional LCD Displays. As well this BenQ Monitor is aproved of TUV Rheinland for flicker free and Low blue light. As well it Auto adjusts brightness (has an light sensor). Becauso of These Features I bought this Monitor, besides it was inexpensive and of an somewhat known brand. I already appreciate now within the first week of the low blue light and flicker free as well as brightness adjustment Features since it drastically improved the eye protection besides the benefits of the IPS Panel. Low blue light is set to minus 50% and brightness is drastically reduced as well in order to not force the eyes. I even take off glasses which I would have never done before.There is an Asus Monitor having These Features as well while other Mayor brands dont have These benefits.It has different Standard modes as well but those have to me an blinding sense effect since they are to bright while (probably) not filtering out the blue light - normal, gaming, movie, etc mode.As well there is an red light filter and an green light filter but those seem to be for Special needed people (it distorts normal colours when turned on). Blue light filter seems not to distort normal Colors.Buy a proper Monitor instead of wearing coloured glasses.Till now the Monitor is Holding up very well and it was well worth the Investment.

[numnum]

thank you, I have now added a blue light filter on my computer and my phone

[beatricerobertson]

I didnt know what is blue light now i understand thank you

[Chillman]

I have UV protection layer for my glasses for myopia. Is this enough to protect my eyes against digital devices?
Excellent 1 hour video by the way. 😁

[micaonyx]

I know this video is over four years old, but hopefully you'll see it and possibly answer my question. I'm interested in buying a red light panel. I've noticed a lot them are including blue lights in the panels, claiming there's health benefits in using blue lights as well. I'm so confused as to what information to trust to trust at this point. Your imput would be greatly appreciated, thanks.

[riccardo]

Great that you trained at a VA hospital, which is where I'm receiving lots of eye treatment here in San Francisco. It seems a typical trait with many videos is really rapid speech; my only criticism of your wonderful videos.

[boodoglover]

I don't have blue light blocking glasses, but I put an app. With a blue light yellowish filter on my phone timed to go on around dusk. Annoying at first, but you get used to it.

[samuelcoudry-lemay]

Excellent and very informative! Helps cut through all the misinformation floating around

[royscott]

I am a nurse so 12+ hours in front of computer screen I wish work used blue light protection

[GianniAzul]

You have the most beautiful blue eyes that I’ve ever seen. I think you chose the correct profession based on that alone. 😂

[georgiak]

Unfortunately we don't have a doctor like you

[davidjones-um]

Dear doctor, I have developed astigmatism right from heavy phone usage( I strongly believe). But I don't have any spherical cylindrical! How on Earth can I get astigmatism from blue light???
