Too late for me to worry about it after a lifetime of working in front of a computer screen.

Yes.

What have you done about your worry, @mtnrdredux_gw? Is it really, @Fun2BHere? Does anyone take supplements specifically for their vision? I know someone with macular degeneration (I forget which type) whose doctor recommended OTC supplements. This Healthline article mentions the specific vitamins and minerals that have been researched.

I do. I use lenses that block blue light. You can purchase them on Amazon or you can add blue light blockers to your prescription lenses. My prescription lenses contain blue light blockers.

My primary concern is the impact on sleep. We try to make sure there is no blue light in the MBR and try to limit screentime just before bed.

Try.

Of course experts have been wrong before but I am not particularly concerned about MD and blue light.

I have definitely noticed my sleep is impacted by blue light and have reduced my exposure to it before bed. (Unfortunately, incandescent bulbs are no longer available in Canada so my bedside lamps have LEDs now....)Thank you for linking that article, @mtnrdredux_gw. I'm not sure how reassuring it is. :/ Disappointed the author didn't answer the questions raised in the comments.

Hmm, my screen time before bed doesn’t seem to impact my sleep. It’s the glass of wine too close to bedtime that does!

Both my parents had MD, Mom never used a screen, Dad did more but still, not until his later years. And my aunt never used a screen but has MD. So I may be doomed no matter what and am going to start taking the supplements. Well, I suppose I should talk to my eye doctor first.

Yes, wine affected my sleep as well, @bpath. I cut it out months ago. Blue light doesn't seem to affect DH's sleep either.

I'm sure many factors are involved in MD, not just blue light from screens. Good idea about talking to the eye doctor about supplements. I'll be doing the same.

My mother had MD so, yes, I do take a Lutein supplement and get regular eye exams. Didn't know about the relationship between blue light/computer time and MD but doubt it will change my nightly habit of spending time on the computer in bed before lights out.

My DH has it and the specialist has him taking Preservision Areds 2.

I purchased a pair on Amazon and I'm sleeping a bit better.

Ive had a lifetime of issues with sleep-- starting in childhood when I used to get up after the house was asleep. Over the last few years, I have made a point of disconnecting from most electronic devices between 9/9:30 pm.. I say most because I go to bed to read on my ipad. This has made a HUGE difference in my sleep. I go to sleep easily and sleep well until I wake up at 5/5:30. I don't and can't credit getting off the electronic devices (because I am still on the ipad) .. but I do credit the mental disconnection from work obligations and the (addictive?) temptation to check one more site, read one more post, watch one more episode. Truly, I think it's the disconnect from work and other obligations that has made the greatest difference. I go to bed relaxed... and stay that way until I log into work in the am.

Blue light is on my health radar to watch, but mainly for sleep impact, as well as the associated time management warnings for my kids. I appreciate my phone's regular updates about "screen time" and encourage my kids to pay attention to that, too. Macular degeneration runs on my maternal side, and I'm regularly tested for early signs. It seems there is a lot of research in ocular diseases, and I'm glad to read Mtn's link above.
