I'm using Firefox.
I got a 25, but then tried the squinty method and got a 7, which I thought was much better!
I, changed to Firefox and it worked!
Three just happens to be my lucky number.
I scored 8 - I'm 66 and need a new prescription for my glasses, so I'm happy with that. Maybe I will do it again when I get the new specs LOL
Did the online color challenge... I scored a 12
I was pretty happy with my 4 - I had to stop when my eyes got too blurry!
