VERY strongly seconding this. I wear contacts I can leave in for weeks at a time and it's fantastically better than glasses. You only need to take them in and out rarely compared to regularly contacts, and you never have to worry about dropping or breaking them. You can wear sunglasses or google glass or whatever with no problems, you can go out in the cold without them fogging up, you don't have to worry about them falling off your head if you do martial arts or a cartwheel, and if you have a strong prescription (my contacts are -9) contacts distort your vision a LOT less than glasses of a similar prescription. You don't have to fumble for glasses when you wake up. You get way better peripheral vision. Obviously way better for sex. The list probably goes on.
To provide the voice of dissent;
I found them irritating my eyes, more so than other contacts. But I'm from not-humid climate, results may vary on the coast. Also make sure you see your optometrist on schedule, mine recommended I stop using them after two years for eye health reasons.
And to be fair, I second all of drethelin's comments about convenience.
On ChrisHallquist's post extolling the virtues of money, the top comment is Eliezer pointing out the lack of concrete examples. Can anyone think of any? This is not just hypothetical: if I think your suggestion is good, I will try it (and report back on how it went)
I care about health, improving personal skills (particularly: programming, writing, people skills), gaining respect (particularly at work), and entertainment (these days: primarily books and computer games). If you think I should care about something else, feel free to suggest it.
I am early-twenties programmer living in San Francisco. In the interest of getting advice useful to more than one person, I'll omit further personal details.
Budget: $50/day
If your idea requires significant ongoing time commitment, that is a major negative.
