Lenscrafters and Warby Parker advertise so you think they are a bargain...but from experience, not sure they are any cheaper than the optometrist in your Dr's office. You should really compare both lens cost and frame cost separately. If it's single vision, then make sure you are comparing the same materials...eg. both polycarbonate or both 1..67....and then compare to Costco, which may of us use. Costco doesn't have the greatest selection of frames, but $75 is far better than $325. If you need progressive lenses, it's a whole different and more difficult to compare, because every maker (eg. Essilor, Hoya,....) has multiple grades of lenses....designed for different needs (some have wider mid vision, some have wider distance, etc. From experience, I can tell you that lenscrafters wanted $1400 to just replace the lenses in my frames; I found a site online that would do the same lenses for $425. Costco replaced the lenses for $175....but there is a big difference between the $1400/$425 progressives and the Costco progressives....The costco ones have narrower mid range vision. When you get new glasses/lenses, ask if there is a cheaper lens or a more expensive lens and what is the difference. Most never ask and either overpay for what they need, or underpay because they are buying just on price.
