Should you wear blue light glasses when watching tv?

Growing Up

Growing up TV wasn’t a huge part of my life. Growing up in the 1990’s we were allowed to watch a couple of shows of an evening on our big back box TVs and that was it. During the day we played outside on our bikes, chased each other about and played sports. Blue light glasses weren’t readily available back then, yet we slept alright.

The technology in the old big back TVs was such that not huge amounts of ultra-bright blue light were emitted. Less blue light means better sleep and less digital eyestrain. This couple with the copious amounts of time I spent outside meant my circadian rhythm was pretty darn good. It meant my hormones were balanced and my sleep was okay.


In 1998 I turned 14. 1998 was a special year for me, I got my first phone and also a TV in my bedroom. I felt like such a baller, an adult, it was amazing! 1998 was also the year my health started to change. I started spending less time outside, instead opting to spend more time engaging with my new roommates, TV and phone! My sleep deteriorated in 1998, I remember it vividly. It was slow at first, waking up at random times, then struggling to get back to sleep and eventually needing to get up every few hours. My energy levels dipped in the day, sport suffered and cognition declined. Maybe it was hormonal, granted I was going through puberty, but later on in life I would come to realise it wasn’t much to do with puberty at all.


Freshly graduated from Exeter University I got a job straight away, working for a recruitment firm. I moved into my first rental flat later than year and the first two things I bought, TVs! One for the living room and one for my room. TVs were different now, they were HD, flat screen and gave out a much brighter image. Low and behold my sleep got worse, my weight went up 3 stone over the next few years, yet I wasn’t eating that badly! The creation of LED lights that shone brighter than before made TVs far more of a nuisance to sleep.


Fed up of getting poor quality sleep I decided to take matters into my own hands and research light and its impact on sleep. Inventing BLUblox Sleep+ glasses changed my sleep forever and for the best. Should you wear blue light glasses when watching TV? It’s a must.
