Blue light filter on computer stuff

[Helene2013]

I've been reading more and more articles about the danger/issues of blue lights on iphones, tv, tablets, etc.

Most of us nowadays have one, if not many, of those devices.

Do you use a blue light filter on your electronic "toys"?

I went for an eye exam 2 weeks ago and opto said she noticed that I have a small spot on the macula. Nothing to be alarmed. May have been there already 10 years ago and never grew. But she took a picture for a follow-up in a year or 2. Also the fact that I have drier eyes (I had lasik done in May 2008) is often related to a lot of computer (which I do). So I have to take breaks every 20 minutes.

But she did ask me if I did a lot of computer/similar gadgets things and yes as I have an iphone, tablet, laptop and HD tv... And I don't sleep well of course as I read from my Notes 10.1 tablet (magazines or downloaded books).

She's asked me to try to use a filter on my tablet at night. Something I was already using, on/off. I find the image not as sharp as it is darker and it changes the look of a magazine page. But if I don't want sleep issues (at least worst then they are) or eye issues in the long run, I have to tone down the blue lights on my devices.

So do you protect your eyes from those blue lights?

because of some client time zone differences i'll have to do some long work hours at night at times and the free app f.lux works for me on a macbook pro. you might try it and just delete it if you don't like it...make sure you use the temperature adjusting sliders to see where the best position is for you.

Thank you. It is the one I downloaded on my laptop after the post I wrote. Will take some time to get use to it as I find you lose a lot of light if you want the full effect of less blue light.

I have a filter on my android tablet and it is "brighter" than f.lux.

I could.not find anything free so far for hubby's ipad and do not want to pay before trying it out.

I've found that f.lux words pretty well on my PC, I use Twilight on my android devices. Twilight is good, but f.lux is better because you can adjust it to the level/tone of light you wish. Twilight is nice though.

Something else to consider. Depending on your laptop's reading software, if I use my backlit device to read on at night then I will change the page display in the software to either sepia or green which is easier on the eyes than the white background. I also like the black background but not at night as the contrast between background and text is too pronounced.

For me, it's been very helpful to make these changes, and I try not to use any electronics in that last 30-45 minutes before bed. It helps me to sleep. I also have dry eyes but for a different reason - scrubbing my eyelids with baby shampoo has pretty much taken care of THAT problem (was very surprised when this was recommended at my last eye exam). Apparently if the pores on our eyelids get blocked then it greatly affects tear production - & I don't wear eye makeup. Very interesting.

Good luck on finding something that works! It would be nice if f.lux were available across more platforms as it really does a nice job without losing sharpness.

on the tablet, when I read a book, I use the sepia background. love it. But wonder if the "blue" still comes out of it.

I noticed while searching the web for apps, that they have glasses you can wear to remove that blue light. Anyone tried them?

I've not used them, but I know people who wear those glasses at home after sunset to help their sleeping patterns. That would be one way of dealing with it - let us know if you try them. I've considered them for myself as I've sleeping problems but haven't tried this yet.

As far as the blue light when using the different backgrounds, it probably still does if you aren't using a light filtering application (which I do), but I can tell the difference even with the filter in place when I've a different background than the traditional white with black text.
