How Blue Light From Screens Impacts Our Health

Traders spend a disproportionate amount of time in front of their digital devices. Unfortunately it’s part and parcel of the job. However staring at the screens all day long can have some serious implications for your overall health. The majority of the problems arise from the blue light emitted from our digital devices. Too much exposure to the blue light from your screens can affect your eyes, your sleep and your mood.

We all know how it goes, you wake up, you check your phone for market moving news. You jump on your laptop to check email, read some more news and check the sentiment on twitter. You trade for a few hours and repeat the process the next day. The working day revolves around your digital devices in some form or another.

I enjoy my work and I plan on having a career with some longevity. If you want to have a trading career with any longevity you must make a point of maintaining a level of good health. You won’t have a long career without it. So what can we do?

Take Regular Breaks

The easiest solution is to reduce the amount of time you spend in front of the screens. Next best solution is to take regular breaks. Every 30 minutes or so make a conscious effort to look away from the screens.

Blue Light Filter Glasses

Repeated exposure to blue light can wreak havoc on your eyes. However you can now buy glasses that limit the amount of blue light that gets into your eyes. The glasses typically come with an amber tint that negates the blue light. The deeper the tint of amber the glasses have the more efficient they will be at keeping out the harmful blue light.

I have a pair of glasses with a slight tint of amber that keeps out 80% of the blue light that I use during daytime hours. If I plan on trading into the later hours of the evening I switch to glasses with a deep amber tint. This ensures the blue light doesn’t impact my sleep. If you are still trading two hours before you are due to go to sleep these glasses are a must and can greatly improve how quickly you get to sleep.
