For years I had worn contact lenses that you take out each night , clean and reuse for about a year. Eventually I went on to wear two week contact lenses that you take out each night and clean and reinsert the next day. Finally they have created one day throw away contacts in my prescription. I feel like a new person. Now that tsa laws have gotten so complicated it is nice not have to worry about travelling with contact lens solutions that fit into a one quart sized Ziploc. It feels so decadent to toss out my lenses each night instead of adhering to a strict contact lens cleaning solution regiment. Its nice to be part of the future.
