Uvex makes saftey glasses that block out blue light. I believe that they make a pair that fits over glasses too. I bought mine online for about $9.00 (regular fit). In the "how do I hack my sleep?" thread there is a link to a source.

Easy way to block out blue light is the f.lux application (which you have) + turning down the brightness of your computer. I have a laptop, so for mine I press and hold "Fn" and then press the down arrow key to turn it down. Very minimal light and I can get to sleep much quicker.

Reading this thread, I decided to test a pair of Remington shooting glasses I have. They have amber-colored, plastic, wraparound lenses. After an initial adjustment of a couple of seconds, I find it quite calm to look at the screen. I am wearing them over my reading glasses.

They cost about $4 on sale at Walmart.

Here is a link to information about them:

...Lens Color: Amber - Increases visibility in low light and hazy conditions. Blocks blue light to help increase contrast and depth perception.

The better shooting glasses with the yellow lenses for shooting in bright light might be well worth testing if someone finds the less expensive ones not suitable.

Hope this helps a bit.

It's not just blue light hitting you eyes. It's the blue light hitting your skin that screws up the sleep notification signals. In fact it's probably mostly the effect on your skin that counts and not the effect on your eyes.

Also take a look at Robb Wolf's last blog post on sleeping and look at the intensities of various lights. Using your computer at night is orders of magnitude too bright. Glasses and f.lux are never going to make up for that.

Got my uvex off amazon, dropped the extra $1 for the sporty pair with mirror finish

They are not fashion glasses tho, quite large

I've seen blue blocking glasses on eBay for just £4.99. They are sold by a seller called rodsnconesdotnet and he claims over 99% blue light blocking.

He's in the UK and the link is http://myworld.ebay.co.uk/rodsnconesdotnet

Hope that helps.

wouldn't it be more to the point to just limit your TV and electronic use in the evenings? I have f.lux too and love it but i think if i need special sunglasses to sit on my couch and stare at the tv all night then blue light is not my real problem. - just playing devils advocate here...i watch tv all night long even though i use f.lux on my pc.
