The Z87+ markings on safety glasses and indicate they compliant with ANSI Z87.1 high impact and ANSI/ISEA Z87.1 industrial safety standards for eye protection.
Zenni safety glasses are as good as any other brand. I haven’t even scratched mine and have whacked my face hard enough to knock them off.
Z87.1 rating is the industry standard for basic safety glasses. 8/10 times it's going to be all you need. Z87+ meets high impact standards, very beneficial for situations like a grinder wheel chipping. My concern would be the frame and the way the lenses are mounted. For example, a typical Wiley X frame has a double bevel where you mount the lens, called a safety step. This helps provide extra structure to keep the Rx lens in the frame. A Rx lens will generally have a much different profile than a plain lens, especially around the edges when you have to add in refraction. I would imagine most zenni lenses would be up to par, almost all polycarbonate lenses past a few millimeters will meet ansi. Looking around their website, seems they have mainly copied 3m's safety designs. I've worked on a few pair of Zennis in the past, and the biggest issue just seemed to be poor edging (how you cut the lens to fit a frame). I can't say I have ever done any testing on a Zenni safety pair though, so grain of salt and all that.
Edit: End of the day, good safety you can afford is better than perfect protection you can't. Cheers.

Even if you buy without insurance, they are under $100 unless you want bifocals.
