My Story with Television and Blue Light

Growing up with a television wasn’t a massive part of my childhood.

Growing up in the 1990’s we were allowed to watch a couple of our favourite shows.

During the day we played outside on our bikes, chasing each other and played different sports. Blue light glasses weren’t readily available back then, yet we slept extremely soundly. most likely because there were not a plethora of digital devices emitting harmful rays of blue laugh coupled with daily sun exposure.


In 1998 I turned 14.

1998 was a special year for me, I got my first phone and also a television in my bedroom.

1998 was also the year my health started to change negatively.

I started spending less time outside, instead opting to spend more time engaging with television and smart phones.

My sleep got worse 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 feeling fatigued.


Freshly graduated from Exeter University I got a job immediately which saw me working in front of a computer screen.

I moved into my first rental apartment later that year and the first two things I purchased were high definition televisions.

The creation of more intense LEDs made using digital devices far more a detriment to eye health and sleep than ever before.


Fed up of getting poor quality sleep I decided to take matters into my own hands and research light and its impact on sleep.

My wife and I invented BON CHARGE blue light blocking glasses to help protect your eyes. These blue light blocking glasses were a game changer and have helped not only my sleep but also improved the sleep of hundreds of thousands of people across the planet.


Blue light emitted from modern day televisions is brighter than ever. It is this artificial blue light that is disrupting our sleep and circadian rhythms.

Blocking blue light from your TV is the first step in regaining better sleep and maintaining a healthier circadian rhythm.

A lot of people believe blue light is only present in smartphones. This is not true, blue light is everywhere that has an LED component, think car headlights, TV, fridge, router, alarms, street lamps, computers, the list is endless.

When you ask the question, should I wear blue light glasses when watching TV, you should ask yourself can I see the colour blue on this TV screen. If the answer is yes then you need to me wearing blue light glasses when watching tV.

This blue light will disrupt your sleep so wearing blue light glasses when watching TV is essential for improving your sleep.
