If you have to use eyeglasses, like anything they wear out. Just had to retire my first pair and on to the second this morning. Normally they last about 2-3 years before a new prescription is needed, but the first pair can wear out from regular, daily use. Having a second pair ready to go and new gives you a bump in vision with brand new, clear lenses and you don't have to stress about spending money months before a new prescription is likely going to happen. Usually a 2-fer is discounted to sell the eyeglasses. I always get mine at Costco as a pair.

I discovered that I didn't actually need glasses. I just needed to eat more lutein-rich foods.
Eat your spinach, nerds!
Hmm, I thought carrots were supposed to be the vegetable that helped your eyesight. That's what I was raised with as a kid. Ate so many carrots I thought I would turn orange. Haven't heard about Spinach. Learn something new everyday.
Lutein is a similar compound to beta carotene, but it’s a much more potent antioxidant in the eye.
I don’t recall exactly why. My optometrist is the one who explained it to me.
Cool, reminds me I need to keep adding spinach in my eggs breakfast and dinner pasta again. Been slacking...
I've had the same pair of Lindberg frames for ~7 years. They were expensive ($800 IIRC), but they've paid themselves off by not needing new ones every few years.
They are a single gauge of titanium wire (don't warp/bend/break) without screws (nothing to come loose). They are so light I can't tell I'm wearing them.
I popped off a nose pad once and lost it so I had to order new ones on eBay, but otherwise I expect them to last for life.
