In reply to climber_Ken:
> my options for eye protection
For protection of the eyes using some sort of eyeglasses / spectacles, normally what's really critical is is not UltraViolet, but rather visible light.
Blocking or otherwise managing UV is critical for _skin_ protection.
But for the eyes ...
UV is much easier to block than visible light, so almost anything that blocks out enough visible light from reaching your cornea and lens will be plenty good for blocking the UltraViolet. But the reverse is not at all true.
For example, ordinary window glass does pretty well at blocking UV, but visible light easily goes right through it.
So evaluate your options mainly based on an percentage of visible Light blocked or allowed (not some measure of UV).
