Computer Glasses - What Do You Think?

Recommended Posts

Hey guys, what do you think about computer glasses?


If you are like me, you are always on the computer at evening time and changing the sleep schedule is a pain in the ***.

My friend started using computer glasses (or blue light blocking glassess or whatever you want to call them) and said it really helped him. Has anyone got any experience?


For those who don't know:

Blue light blocking glasses are glasses with special lenses that block all the harmful blue lights that are coming from computer screen & phone screens.

These blue lights make your brain think its daytime and affect natural melatonin production in your body. They say that wearing these glasses for 1h+ at evening will make your body will start producing the normal amount of melatonin.


Here is a good review of blue light blocking glasses

Hey guys, what do you think about computer glasses?

I’m curious about them, both as relates to a scientific subject – how light affects sleep and arousal – and personally – I sometimes sleep poorly, and would like to sleep better.


Not the best internet posting on the subject, in large part because DiscoverASMR is a website dedicated to “autonomous sensory meridian response”, a recently (2010) coined term that’s yet to gain widespread scientific acceptance as something real rather than due to suggestion and peer influence. Real or not, ASMR is a discussion-worthy subject, but distracts, I think, from that of the effect of light on sleep and arousal.


While only informally scientific, I found this 27 Apr 2015 TheConversation article a better article on blue-filtering, orange-tinted glasses and sleep.


Lacking from most of the commentary on and accounts of informal self-experimentation with blue-filtering glasses I’ve read is spectroscopic data. I’m planning on buying or building a convenient visible light spectrometer to measure the spectra of various light sources in my daily environment. In particular, I’m curious to see if my suspicions that the light from an backlit e-paper tablet (eg: an Amazon Kindle) is less blue than that from a typical backlit LCD tablet (eg: Apple iPad).
