Out of curiosity, why spare contact lenses at the top of the list (especially versus spare glasses)? Do you consider contact lens solution to be part of the "spare contact lenses"?

When I used to wear contacts and I wanted a back-up, I chose glasses, since contact lenses required so much care (clean hands for handling, solution, easy to loose if dropped, etc.) Has contact lens technology changed that much in the last few years that such care isn't necessary?
