Also figured Chris, in his excitement, would have left any black shades he owns at home.

That's a stereotype, if one is 100% blind they don't require shades. The sunglasses are used for people who have enough eyeball functionality to see vague imprints and light sources. This is clinically blindness and the remaining sight is often more of a hindrance because the sudden light and dark contrast can be disorienting and painful. Those blind people use shades to block out that last 5% so it doesn't get in the way.

The only reason for someone like Christian to use shades would be as an identifier but as previously stated he doesn't like using those if he can help it. 

Also just a note, unless someone has worked with the blind before there is very little chance of them associating fogged eyes with blindness. Light blue eyes that almost look like mist aren't that uncommon.
