>- Eye strain caused by lack of contrast due to our favorite color palette. An anecdote: A couple of years ago during a stressful time at work I was fitted for prescription lenses. While being indecisive about choosing frames, I installed f.lux and reduced brightness of my monitors. Never ended up buying glasses, and in a couple of weeks my vision was back to normal. It was just eye strain, and I saved about $300. Edit: changed "Flux" to "f.lux"
