Today I spent a lot of money. When you buy many items, you have to decide whether the basic model meets your needs or you want extra bells and whistles. In most cases, add-ons aren't really worth it, but sometimes you find that the money you could save doesn't compensate for the frustrations of using something that doesn't quite do everything you wanted.
I got glasses the summer I turned eight. My vision has finally stabilized, but my myopia and astigmatism are pretty severe. When you go to price glasses, clerks ask to see your prescription so they can tell you what the lenses will cost. Often, the response after they look at it is, "Oh. Oh, wow." I can't function without my glasses, and I wear them pretty much every waking minute.
I'm willing to spend more to get glasses I like. Shatter resistant polycarbonate lenses and Transitions lenses that get dark in sunlight are a priority for me. I tried going back to ordinary lenses, and I spent a year wishing I hadn't. The less expensive lenses were a daily annoyance, and I resolved to stick with the pricier but superior option. Is this lifestyle inflation? Sure. Does that bother me? Nope. When I consider the cost per wearing, getting the glasses I want is the only sensible choice.
I've been wearing my current glasses for two and a half years, probably for an average of sixteen hours a day. Since my vision is no longer changing much at all, I'll almost certainly keep the new pair for at least two years. Getting polycarbonate and Transitions instead of basic plastic added $110 to the costs. I'll gladly spend an extra fifteen cents a day.
