A long time ago people were afraid of understanding how the natural world worked. Fear, ignorance, superstition, sudo scientific beliefs, and religious zealots, were prevalent. These times were called the dark ages.
My monitor has some thing to suppress blue light and relieve eye strain i think most monitor do. I do have my monitor on gaming mode so its probably not active lol.
Avoid blue light. Eat fresh veggies and fruits; avoid junk food. Don’t smoke cigarettes. Exercise. Go to the gym. Take a bicycle to work. Do yoga. Meditate.
