A few months back, my DH had noticed a problem at work. He was having difficulty w/ the color red. If it was part of a sign or a background, it was hard to discern. He went to eye dr and they did test him for it. They had a computer screen, half red/half green w/ letters and numbers on the colors. It is definite. Red is a big prob for him. I generally don't have a problem w/ colors, but I have a terrible time w/ red, too. Sometimes, when they run the credits on the screen (movies and/or tv) they have red print or red background. WOW, that kills my eyes. I love to stay thru the credits, but not w/ the red. I have gotten sick from that on the screen.
Interesting thought, Donna!!
God bless. Alice.
