They may take a day or two to get back to you but this guy really seems to know his shit about eye safety. And no I don't have any affiliation :).
Good Luck and Happy Growing

(gladstoned),

Thank you for your email.

Metal Halide bulbs are supposed to be made with a UV blocking coating on them. However, many users still complain of symptoms consistent with photokeratitis, a condition that results from ultraviolet over-exposure, so it's possible that not all metal halide bulbs are being properly coated. In any case, eye protection is certainly recommended.

As you probably know, the metal halide bulb emits a broader spectrum and renders a more white light than does the more focused HPS light. As such, the emission of UV light from a metal halide bulb is significantly higher than that of an hps bulb and, coating or no coating, should be used even more carefully.

All polycarbonate lenses block at least 99% of UV light, with most being in the 99.9% range. This applies even with clear lenses. Only in a few cases does UV protection significantly increase with changes in lens tint. The orange lens by Uvex is shown to block most light under 540nm. Graphs for Pyramex' lenses of Sun Block Bronze (copper) and Shooter's Amber show light under 420nm being blocked. Most lenses that are better at blocking the blue light range (copper, amber/yellow, brown/bronze, orange, etc.) will naturally be better at blocking the neighboring range of UV as well. Shades designed for blocking IR for milder welding applications, that is Green Shades 3 and 5, also tend to block UV very well, however visibility is also sacrificed with these tints. You may consider any of these for good UV protection.

In the case of sodium vapor lighting, many prefer to use a blue lens, which neutralizing the more yellowing effects of the light. High Pressure bulbs are not as yellow/orange as Low Pressure, however, and may not require such a tint for long term comfort.

Talked to several Optometrists.
Yesterday went to Lens Crafters.
Got glasses, but I ordered contacts too.
Once the contacts come in I will try them for a few days,
If/when they work, I will order the Method 7 sunglasses.
