Either way , it doesn't matter.
A half millimeter makes no difference either way.
Most of the online sites screw up the PD by a couple of millimeters anyway.
Optician
Footprintz is right for the most part. A millimeter difference has no problems at all, but high quality sites would not botch your prescription like that.
If you're looking for an alternative site that provides better glasses, try this: http://www.optical4less.com
I only recommend them because I've been buying glasses online for years now and they're one of the better ones online. Other places really will get your PD wrong, but every time I checked the glasses from optical4less with my optician, they've been almost always perfect.
