There are a few criteria I've gleaned from google time spent that I think makes sense to include.
First, seems like there are three specs that are in common use: ANSI Z87.1 in two variants ("Z87" basic impact and "Z87+" high impact) , or Mil-PRF-31013. There are some glasses that pass both the ANSI and the Mil specs. The OSHA spec also requires side shields for side impact protection.
Second, I must have glasses with prescription inserts that can support a bifocal prescription.
Third, I'd like some interchangeable lenses, at minimum to include clear (indoor range), a yellow or equivalent (ordinary outdoors, hazy/cloudy), and a dark lens (bright sunlight).
One option I am considering is the ESS ICE Series eyeshields that passes all three specs.
Although more expensive does not necessarily equate to better protection, I am concerned with getting the best protection I can afford since I am already blind in one eye.
So, I am interested in opinion/feedback on several aspects:
- Do these criteria makes sense,or am I missing something?
- Anyone have experience pro or con with ESS?
- Is there a better choice I should consider?
