[Star Trek TNG] Why isn't the technology that allows Geordi to see more widely used?

His vision is far superior to "normal" vision. I guess I can understand people not wanting the surgery for the eyes we see in the later movies, but doesn't everybody have a visor like his? They're extremely useful. Who wouldn't want to see almost every spectrum of light?

It strains your optic nerves and causes headaches. Geordi talks to Dr. Crusher about it in one of the first episodes. Her only treatment options were surgery to deaden the nerves, or medicine to do it without opening him up. Both were denied by Geordi because he claimed they would make him less efficient.
