It isn't a problem.

Just like monitor manufacturers don't offer prescription glasses along with the purchase, Oculus won't offer lenses.

Corrective eye-wear is very individual and requires some amount of expertise( exam, specialist ), so it doesn't make sense, and it isn't very feasible, for Oculus to provide that for you. Also contacts are very cheap.

Monitor manufacturers don't make a device that straps onto your head. Apparently wide frames are an issue[1]. When I was playing airsoft, I had ESS goggles. ESS also sold prescription lenses[1] designed to slot into the air holes in the goggles, all you had to do was send them your prescription.

Contacts may be very cheap, but even with dailies, I wouldn't want to put in contacts just to game. I prefer glasses in general.

I thought the dev kit came with lenses specifically for near-sighted people.

It does but this is because you can't easily wear glasses under the devkit.

Couldn't you just correctively blur the display or something?

That's not beyond the realm of possibility, but it would significantly reduce the performance of the display:

I would like to see driver support for punching in the numbers on your eyeglass frames to adjust the focus to the prescription automatically.
