I'm blind as a bat without my contacts. Actually, what with sonar and long fangs for blood sucking, I think bats can see much better than myself. If I don't have my glasses or contacts, I just stumble around trying to feel my way along the wall until I get wherever I'm going. So I printed out this free LensCrafters lens cleaning kit coupon and will promptly be picking mine up the next time I'm in town. The last thing I need is run off the road because I couldn't see through my dirty glasses!
