Don’t look at the sun!

A couple of days ago I was driving home and came round a bend to see a bright red sun on the horizon. For a second I stared at it then realised it was dangerous and looked away. But it was slightly too late. Now when I look I can see a slight bright patch where my eyes had wandered across the view. It’s faded a bit so I guess I haven’t done permanent damage but I will try not to do that again!

When I think about my vision I am so happy that I can see with the full spectrum of visible light (colour) . I know different animals can only see certain colours, sometimes just black and white and but others like snakes and insects can even see into the infra red and ultra violet.

Then there is colour blindness, where some cells in a person’s eye are not properly developed or can be missing. Then they have colours missing from their vision. For instance red green colour blindness. Apparently males suffer from this more than females. As I say I feel lucky to have good colour vision. X
