I've worn contacts for about 35 years now. I used to wear some very high dollar contacts that corrected my stigmatism and I kept a pair for as long as I could which was usually about 1.5 years, then replace. But now I wear the extended wear disposables type and these allow a lot more oxygen to the pupil which allows me to wear them for a few days without taking them out, if I so choose to, but for the most part I take them out daily. These newer contacts are much for comfortable, especially when worn for extended periods.

Laws aren't preventative measures. In other words, more laws won't prevent gun crime from happening.
