One of the best things about being very nearsignted and wearing glasses is, as others have noted, the power to slip away from reality a little bit. The best part about it is that it isn't considered rude: If I have to converse with someone that I (unintentionally) find repulsive, I can easily remove my spectacles, perhaps under the guise of cleaning them, and spare myself some visual agony.
Sometimes, wearing spectacles helps me remain objective about the world: No matter where I look, I see towards the edges a dark edge, and beyond that, the combined bokeh of peripherial vision and myopia.
Additionally, spectacles sometimes serve (when lucky) to protect one's eyes from unexpected contamination and injury.
