Shall we list the non-perverted uses of invisibility?
...in truth, blindness actually makes a lot of things hard... but if your retinas only interact with light from the front, and if light were shined off the back to imitate the light stopped by the retinas, you could still see. In addition, if the power functions by bending light (or some combination of light bending and transparency), you wouldn't need to be naked. This opens many more possibilities...
Journalism is too dangerous if you are blind- just try to sneak into North Korea that way... If you can see, it becomes far more possible- but watch out for infrared cameras, sonar/radar, animals with a good sense of smell, and other alternate means of detection... you may not be able to get inside secured areas.
If you're not up for risking your life, try starring in the movies- using you is likely cheaper than green screen effects. On a similar vein, you could host the world's best puppet show.
If theft comes to mind... firstly, shame on you. Second, it's hard to miss floating goods and money- unless you have light bending invisibility, and you're hiding it in your clothes. This will not stop those exit scanners or radio tags, however.
You could see free movies, and get free air travel (as long as you don't bring luggage.)
You could pull off incredible pranks, scare campers silly, and otherwise show off.
And, of course, you can avoid people you don't like. Sometimes, the best uses for something are the simplest.
...I should say, however, that even when ignoring... certain applications, many of the uses for invisibility are of dubious legality and morality.
