Anyone with glasses, if it happens to apply I feel like I thought I'd mention. My general strategy to cover vision costs when you don't have vision insurance:

1. Go to an eyedoctor in an eye store and see if they have free appointments for people who buy glasses there. If so, get an appointment and ask for a paper with your prescription or write it down. Then don't pick out glasses that day or consider but don't buy. Worst case if they make you purchase you may have to buy one expensive store cost glasses. You may want to see if purchasing glasses same day is required ahead of time.

2. Go to an eye doctor who's in an eyeglasses store who's first visit is maybe 20-60 dollars. The store will assume you're buying from them, but it's not required. You get your prescription from the doctor from that one time cost. Then leave without buying glasses.

Now go to zennioptical.com or eyebuydirect.com. I went to zennioptical first because they explain measuring your own pupilary distance and frame sizes etc. Then go in and pick from your choice of 9 dollar to 35 dollar frames, with add ons to your lenses if you desire blue light filter etc. The end cost even if you get a lot of extras is usually 60-80 Mac, and if you just get base glasses usually 20-30. Whereas in glasses stores I was looking at 410 dollars for glasses back when I had vision insurance.
