Does this thing really work?
These are blue light blocking glasses that promises to filter the harmful light from electronic screens, like cellphones, tablets, and computers. According to the product description, blue light causes eye-strain and headache when using these gadgets especially for longer periods.
As someone who had lasik eye surgery, I am all for protecting our eyes. I don't want to have to go back to wearing corrective lenses or contact lenses - they can be pretty fussy, and costly as it all adds up. So I got suck into it and bought one. To be honest I cannot really tell any difference. I still get the occasional headaches that comes with stress and for working long hours without rest, but not really sure about the glasses. I bought one from Amazon for $12-$15, and I admit that oftentimes I forget wearing them when working in front of my computer.

LED screens do tend to give off more light from the blue end of the spectrum but then so does the sky. It has been shown that blue light tends to make us wakeful but it's not the light which causes eye strain and headaches when using screens, it is the extended fixing of the eyes on a small area at a constant distance.
Glasses with a slight orange or yellow tint might be useful if you find yourself unable to sleep well because of using the computer in the evening, however, I suspect that glasses wouldn't be necessary because many phones and computers have a 'Dark Mode' which will reduce the amount of blue light given off at certain times. You can also adjust the colours of TVs and computer monitors manually if you find them unpleasing.

Really? I don't know that "blue light" can be found in nature as well. Oh well, I guess I wasted $12-$15 for this. But I will try to use this tonight when I am about to sleep - I tend to forget and still keep browsing on my tablet, then when I had enough I do find it hard to sleep.

@Raine38 if it's an Android, look in the Settings menu for 'Display'. You should find a 'Dark Mode' or a 'Night Mode' option which will reduce the blueness of the screen automatically at night.
Of course, the 'wake up' signal of blue light is very natural. When the sun is up and the light is bluer, we should be awake and out hunting (or whatever!). When the sky turns yellow or orange and the fire glows red, it's time to crawl into our caves and piles of skins and sleep!

@owlwings I was able to put the settings fr my phone's LED under the individual settings of each app, like Facebook in dark mode.
It did not occur to me that our biological make-up recognizes blue light as a signal get up and move which contributed to our survival. After all, human beings were never at the top of the food chain. But time's have changed.
My husband has an android phone for work. I will use your suggestion so his eye strain can be avoided.

I do feel the strain of working long hours on the computer not so much on mobile but I am not sure the harmful blue light blocking glasses will work to safeguard the eyes. I have never used them. Your experience may be guide to us as you have already started using them.
