Front wipers - wipe footprint

Hello, I just began with the Prius life (2010 Prius III) and it's nothing short of awesome and unlike any other drive experience I've had up to now (in a good way, of course!) So, I am wondering if it is normal for the front windshield wipers to miss a somewhat small portion of the windshield when wiping. The area I speak of is lower passenger side, and arcs upward and to the left.. roughly the area (but not shape) of a standard notecard. I am pretty sure my wipers are the correct length (19" & 26"). All other cars I've driven up to now does an otherwise full footprint worth of wiping (ignoring the top and side edges, of course). So here are my two questions:

1) Is this normal?
2) Has anyone successfully changed their wiper length to minimize this gap?

This is not a huge deal by any means, it merely creates a pesky streak of fluid any time you use the wiper wash fluid while driving (you have to dry wipe the windows a number of times after wash-wiping it).. and maybe somewhat blocks the view of the passenger.

Thanks in advance! Again, not a huge issue--just curious as to whether this is normal or not and if anyone has found a work-around.

 

Sorry for the delayed response. I will get a picture the next time I get a chance. The area I speak of is outside the blade radius on the bottom passenger side. It's a skinny swath that is created between the two blades. Thanks again for the comments and suggestions!

 

Here is the swath I'm talking about.
