Technology advances so quickly. I feel like I’ve been staring at screens my whole life, whereas my Mom just started using the computer only several years ago!
When I began my first job, where I was required to look at a PC monitor screen for 8 hours/5 days a week. I started noticing pretty quickly that my eyes were becoming strained. My eyes wouldn’t adjust as quickly between near and far, as was obvious when looking in the rear view mirror in the car. I developed floaters in my eyes. In the last year, the number of floaters in my eyes has increased 15-fold. I’ve also developed blurry spots in both of my eyes.
I’m not saying that the eye floaters and blurry spots are caused by looking at screens for so many hours each day, but I’m sure that whatever IS the root cause, is being exacerbated by so many hours of screen time.
So why are screens a potential culprit? And how to remediate?
PC monitors as well as Mac monitors use various lighting — in the past, CCFLs were often used, and now, almost all screens (i think) are lit with LEDs instead. I won’t go into crazy detail, but I’ll mention that the brightness of LEDs can be incredibly damaging to the retina. Our eyes weren’t built to withstand the bright bright light of the LED, especially at close range, which is like shining a floodlight into the retina. If you decrease the brightness on your monitor, another problem is created that causes further eye strain – via Pulse With Modulation (PWM) – you can read about it here, and test your screen with the information found here.
Another problem is the disproportionate blue and green light ratio to other colors in the light spectrum – LEDs are very heavy on the blue light.
All of these issues can be remediated by using an app called “Iris.” Here are the most important features to use in Iris:
- Brightness decrease: it is important to understand that to avoid the damage from PWM, you must set the brightness of your screen at 100%, and then decrease the brightness WITHIN the Iris app settings.
- Blue light decrease – make sure you put on “Health” mode at the very least, and then decrease the Blue light in the Iris app settings.
- Break timer – you can turn on the timer in the Iris app settings. I set mine to “Strict”, and every 20 minutes, the app makes a beeping noise, and the screen goes grey for 20 seconds. During these 20 seconds, I get up and look at a distant object. This is a healthy practice for our eyes!

There are many other features within the Iris app you can play around with, but these are the two most important.
Electromagnetic radiation (also known as EMF or EMR) also damages the eyes, which you can read about in the BioInitiative Report. The best way to remediate this is to remove all sources of wireless radiation in your home (hard wire your laptop with an ethernet cable and get rid of your router) and shield the smart meter installed on the exterior of your home.
