Not saying anything about your route of getting glasses, but as a fellow person who cannot see and is poor, I do have a suggestion for some cost savings. Just a suggestion that may get you more bang for your buck
You can go to Walmart for an eye exam, and they typically have the cheapest ones I know of, around $100 last time I did it. Then, you take those results and buy glasses online. I've seen sites with glasses for $30-$40, so you could get multiple pairs of glasses, even a pair of prescription sunglasses which are great for driving.
