Window tint darkens the interior and to a degree some kinds of it protect your eyes from ultraviolet radiation. But, no, it doesn't typically make the interior cooler when the vehicle is standing still. Since heat absorbed by the window tint heats the glass itself, though, when the car is moving and the outside surface is cooled by fast-moving air it may get rid of a lot of the heat without heating the interior.
If the window tint is of a kind similar to that used on office buildings, it will reflect most of the infrared and thus reject the heat you'd get from the infrared. I have no idea whether the window tint used on cars is made that way, though.
Even if the window tint doesn't keep the car cooler, it's still worthwhile for keeping the sun out of your eyes and concealing your activities from other citizens. That's what it's for, eh?
