On Feb 01, I ordered a couple pair of eye glasses from Zenni Optical. They arrrived, Feb 21. As they write on the web site, bifocals and complicated lenses take longer. So, the time was about right. And yesterday was a holiday.
I took my Zennis out for a drive. There is fading daylight, but plenty enough to see. The bifocals I bought for "daily wear" are not strong enough to read street signs. Each time I'd had to buy new glasses, it was because I could not read street signs. I'd have to get close, a couple car lengths from the sign, before it was in focuss. Well, guess what, that's exactly what these glasses do. Not enough correction for me to read street signs.
Not much benefit for my money.
I have emailed the Zenni service email adress, and will let you know what I hear. And, I'm going to put my old eye glasses back on.
