I went to the optometrist, and my prescription got strong. She warned me about being at risk for losing my vision.
That's not good. I know my eyes hurt when staring at the bright white screen on computers . So I change them to a darker color when possible.
Oh yes. That is smart. After the warning, I use the screen dimming program called f.lux.
Haven't tried that yet, but I have heard of it. I will check it out. thanks !
