The lenses in your eyes refract different wavelengths at different angles - think of a rainbow coming out of a prism. Only one wavelength can be perfectly tuned to project a clear image onto your retinas. We are optimized for green, red is close enough, but blue always looks blurry.

Huh, I like that theory. Nobody else has ever mentioned experiencing the same thing as I do, though.

It's called color aberration and a big thing in telescopes using lenses.
