Buying glasses is a hassle, strong dislike! Bifocals/progressives are expensive. Stores here (nordics) upsell annoyingly, on both frames and lenses. Never regular prices, always sales or 2-for-1 style campaigns. Hard to tell apart quality steps from mere money grab upsells. For progressives different stores offer 3-5 lens qualities, each using vague naming like "better" and "supreme", so cross store price/quality comparison is opaque. Then there's lens thickness options (1.6, 1.67, 1.74 where higher is thinner and costlier). One store said 1.74 is the only feasible option with my -7. Another said 1.6 is ok if I don't mind a thick lens look. Lots of treatment options (basic anti scratch vs more "advanced"). Expensive to just iterate (buy, try, buy differently), especially since the presbyopia will worsen over a period of years, which means buying new again in a year or two.
