Last week I went to the Vision Center at Walmart to get my eyes checked. The nurse took me into one room where she checked my peripheral vision, eye strength and then shot that wonderful puff of air onto my eyeball. Then she asked me if I could read the numbers inside the colored dot pictures. I thought I did well. I saw the numbers 3, 4, and 12. I saw three out of twelve numbers. She asked, “Do you know if you’re color blind?” “Yes, I am very color blind.”
