howdy,

wanted to post this just in case...

so, went into the greenhouse to do a little tidying up. the UVB lights were on during some work under them. went to bed n my eyes were stinging for about 4 hours after. I think I might have irritated them while exposed to the uvb.

ok, not doing this again. uvb lights off next time.

yea man def turn off the uvb light next time. uvb light is very harmful to your eyes and skin
Eye

"High intensities of UVB light are hazardous to the eyes, and exposure can cause welder's flash (photokeratitis or arc eye) and may lead to cataracts, pterygium,[19][20] and pinguecula formation.
Protective eyewear is beneficial to those who are working with or those who might be exposed to ultraviolet radiation, particularly short wave UV. Given that light may reach the eye from the sides, full coverage eye protection is usually warranted if there is an increased risk of exposure, as in high altitude mountaineering. Mountaineers are exposed to higher than ordinary levels of UV radiation, both because there is less atmospheric filtering and because of reflection from snow and ice.
Ordinary, untreated eyeglasses give some protection. Most plastic lenses give more protection than glass lenses, because, as noted above, glass is transparent to UVA and the common acrylic plastic used for lenses is less so. Some plastic lens materials, such as polycarbonate, inherently block most UV. There are protective treatments available for eyeglass lenses that need it which will give better protection. But even a treatment that completely blocks UV will not protect the eye from light that arrives around the lens."
if you have to work with the light on get a welder's helmet or something simialr and cover your body with clothing.

I asked in another thread if UVB lights were harmful & nobody replied so thanks for the info.

thank you for the detailed post!

yes.

and it doesn't take long to feel the burning sensation. i was only under them (2x 48" 10.0 uvb) for about 15-20 minutes without any eye protection.

oh, well, lesson learned
