My two bedrooms upstairs share a wall space for an air return. The wall has an upper and lower return vent. You are able to see directly into the adjacent room from the vents. Is there anything that can be done to block the view and dampen some of the sound between the two rooms?

You could tent a piece of duct board at a 45 degree angle to the duct in the space between forming an A shape. If the return is served by two intake grills on both sides, the sound would partially bounce into the duct while partially being absorbed by the duct board, and light certainly will not bend around it. It would not be perfect, but it should cut the sound down considerably, and the light down totally. If there is not enough room to do the full A, a single in between would at least reflect sound back and have the same net effect on the light.

Since the OP stated one of the airflows goes down, you could likely solve it in either direction with a more ellipsoid, as it would be best for airflow. Tape the board at both ends, and insert something in the middle. Turns out drawing an ellipsoid in ASCII is hardenter image description here :-)
