I got contact lenses back in middle school. At the time my optometrist thought that hard lenses would keep my eye sight from deteriorating. I'm not sure if it worked. I can tell you that the lenses were a real pain. They were smaller than my irises and prone to trapping tiny dust particles underneath, which burned and stung. The only way to get rid of them was to take out the lens and wash it. To make matters worse, hard lenses can't just be plucked out of your eye, you have to push it out with pressure on your eyelids and they can slip off the right spot and adhere to a different part of your eye ball. I had a little plunger for these cases, but they did little to alleviate the terror of having a bit of hard plastic stuck to a random part of my eye. In high school my eye sight seemed to have stopped rapidly deteriorating and I refused to wear the contacts anymore. My eye doctor gave me some cheap dailies, which are easy and painless, but I think I've lost my taste for contacts and pretty much only wear them for kendo now.
