In most home forced hot air systems, the vents near the ceiling are return air ducts - taking the room air back to the furnace to be re-heated. They are always open - there is no way to close them as with the hot air registers near the floor.
If that's what you've got, they are typically installed with the vents slanted down (hot air rising along the wall will flow more smoothly through the vent into the return air ducts. But if you don't like looking through them to the inside of the return air duct, turn them around - no safety or esthetic penalties for doing so.

Some newer homes have supply vents in both the ceiling as well as the floor. The floor would be closed in the summer and the ceiling would be opened. Warm air rises and cold air sinks. Some homes would use a zoning system to help this. For comfort a variable speed unit would be ideal. No return vents will have dampers on them they will always be open. Changing the vents up or down wont change your flow very much unless you have a volume of air moving through them. Heating would be down cooling would be up for the reason of heat rises and cold sinks.

??????? Are you running AC or Heat? Are the vents on the wall near the ceiling? Do you also have ceiling fans in the room? If you are running AC then turn the vents UP and turn the ceiling fans to blow down. If you are running the heating unit then turn the vents DOWN and put the ceiling fans to pull the air up from the floor.. Remember from SCHOOL heat rises COOL air falls

Most vents are in ceiling. But.....having them slanted downwards would propel the heated or cooled air towards the occupants making them feel warm/cool quicker.

For heat, aim downward since hot air rises. For cool, aim upward since cool air drops.

that is more of a comfort question wich would be at your discretion, but you take into mind that heat rises it could change from season to season, but your grill should blow to the exterior wall, and then your return will draw it back across your room
