Why the $20 cap, you ask? The answer is simple. Let's consider the reason you are purchasing these sunglasses.
Now, if your reason for a new pair is that you are an environmental researcher who just got back from a 10-year-post in Antarctica studying the effects of global warming on the polar ice caps, and, having not seen the sun in a decade, have had no use for this important accessory until now, please feel free to disregard my rule and purchase whatever pair of sunglasses will make you happy. Welcome back to civilization and sunshine, and thank you for all you do for our Earth.
But if you're just the average shopper in the market for a new pair of sunglasses, your reason is probably one of the following:
- You lost your old pair.
- You broke your old pair.
- Your old pair went out of style.
And let's be realistic -- without a doubt, before long, one (or more) of those three options is going to happen again. It's pretty much a fact of life. So rather than putting yourself in a position to mourn the loss (either literally or stylistically) of an expensive pair of sunglasses, follow my rule and move seamlessly on to sunnier days.
