if they are coloured then don't wear them... it looks tacky and you don't want to remember yourself in your wedding pictures as someone who wasn't showing her true eye colour.
Otherwise, wear them. You don't want to be squinting at people at a distance or not be able to watch dances... you want to enjoy your own wedding and you must be able to see with two clear eyes with a good vision to do that.
In Pakistan most of the photographers color your eyes to match your outfit anyway! I specified that I did NOT want that; I wanted my natural eyes. They still did it on a couple of photos (my shirt was green, so they matched that).
