I guess there's nothing to prevent you from wearing disposable lenses for longer than their recommended time. However, my lenses feel so much more comfortable after I switch them out. This is in part to two things. First, the lenses (which are about 98% water) start to lose some of their elasticity after a few weeks. Slowly the lenses lose their moisture content. Second, one of the inevitable byproducts of lens wear is protein deposits on the lenses. They usually aren't noticeable unless you hold them up to a light, but they cloud the lens. They sell enzyme cleaners which claim to break down the protein (but don't), but why bother when I can throw in a fresh, moisture-rich pair of lenses. I wore extended wear when I was younger and could never imagine giving up disposables now.
