After I got over Denzel’s shaving mishap, I noticed his eyes. I was about to say something about them. At first glance, the irises looked blue, and it seemed like his pupils were VERY dialated. I looked closer, and saw his brown eyes, and normal sized pupil. So that blue or gray area around his irises is probably due to getting older. My mom has the same thing around her brown eyes. I think it might be a symptom of glaucoma too… not sure.
