OMG, I need glasses! What would you do?

Yes, having that extra coverage is great just in case "something" happens to the glasses.  My pairs of glasses has everything BUT transitions, as that's an extremely expensive add-on that I can't afford.  I rather keep a nice pair of sunglasses just for that.  For reading or computer use, I also have another pair... but for going out and driving, I have issues seeing further.

I used to keep a pair of prescription sunglasses to go along with my regular glasses, but it was expensive and inconvenient to always have to carry multiple pairs of glasses. Once transitions came out I jumped at that since it is cheaper than a second pair of glasses and is so convenient. Plus, from what I am told, they are blue-blocking by nature, so you can also use them as computer glasses.

So I generally have transitions on all my lenses these days. I only have to worry about a single pair of glasses, which I generally only replace every 5 years or so. So I find them to be pretty cost-effective if you look at that cost as offsetting the other costs.
