I live in the Czech Republic, good glasses with a titanium rim will cost about 500 eur and last for around ten years.
I personally prefer daily contact lenses (the kind that you discard before sleep) which cost me about 400 eur a year; I know this is a bit of a luxury, but even this only touches the 1% of yearly developer income. Glasses would be in the 0.x% category, depending on how much your acuity changes over time.
