I got UV induced eye irritation but it didn't earn me a web page. It won me a trip to the web to learn that (1) snow blindness is a real thing, (2) the snow doesn't have to be literal snow -- pale ground works too.  Not as bad as this guy's, luckily, and all better the next morning.

Maybe more of a lesson on how to properly install a UV light in a pond....Normally these are encased and water pumped through the case, rather than just plopping them into the pond or aquarium.

That is why I make sure I have good sunglasses when Winter hits. I prefer polarized, but you would be shocked to discover how many displays of various types become completely black unless you either take off the glasses or angle your head.

I worked in a steel boat weld shop for a winter so I've learned to look away or block the welding sparks -- even now 25 years later while watching TV shows. I heard plenty of stories about the temporary blindness.

It was rather odd to be in Michigan in the winter with a nice tan on my face.

yeah why don't the fish all go blind? Does UV not go through water?

Consider this: Even knowing UV causes skin cancer and retinal and coronal burns, there are still no OSHA guidelines or limits on UV exposure.

Because OSHA does not consider UV ionizing radiation:

The non-ionizing radiation standard only covers the radio frequency region, including microwaves. The ionizing radiation standard covers alpha, beta, gamma, and X-rays; neutrons; high-speed electrons and protons; and other atomic particles; but does not include sound or radio waves, or visible, infrared, or ultraviolet light. Therefore, there are no OSHA-mandated employee exposure limits to ultraviolet radiation.
UV is poorly defined as near-UV isn't ionizing but higher frequency UV is and there's essentially no labeling or proper education or warning.

Hey TSA: those UV lamps you're staring at all day to check IDs may be blinding you.

Good.

In my trade as an ironworker we call this flash burn or flash. It is basically a sunburn of the cornea. When the tiny blisters pop your eyes will remain shut because air will cause extreme pain. Eye drops that "take the red out" are no help and promote infection by shrinking blood vessels. An old remedy is to cut a potato in half and place over eye lids. I guess it draws the heat from the burn.

Yes. It works awesome in my pond.

Also, get an enclosed one that you run you pump through. Works better and no blinding.

If you install them correctly, they're enclosed in the hose or pump of a filter along with your mechanical/biological/chemical filtering stuff. Neither you nor the fish should ever have it shining on you, let alone in your eyes.

Snails can get in there, though, so maybe you'll have some blind snails getting in tiny slow motion collisions.

Like a burn you get from looking at a welding flash.
Even the reflected light will get you.
A flash or two is not that bad, but you cannot tell when you reach the point where the burn starts until it is too late.
Feels like there is about a teaspoon of dry sand in your eyes.

I weld in a confined space area with multiple welders all around me. People are constantly getting flashburnt from the welder behind them's rays being bounced off the inside of their helmet.

reggaejunkiejew: yeah why don't the fish all go blind? Does UV not go through water?


UV has a really hard time punching through a lot of materials we consider clear.  Take glass for example, standard windows pass almost no UV.  I believe you can get decent transmission if you use quartz glass (you won't find that in your house windows) but even then there's probably some fall-off.

I always think it's weird when I see cheap sunglasses with plastic lenses advertise "UV Protection".  It's more of an unaviodable property of the lens than a feature they added.
 
2014-04-23 10:07:33 AM
The fool was running the bulb out in the open. You are supposed to have it in a matching housing with pump which keeps the UV light from hurting your eyes or your fish. It pulls the water in, passes it around the bulb and then pumps the sterilized water back into the tank at large.

I currently have a filter with it built in. This One I got the 2500. My pond is about 1100 gallons so I went overkill.

Before that I had this one but I left it out one winter when I shut down my pond and the case cracked.

Typically, it's built into the filtration system and not shining into your eyes.

"Who knew that such a small lamp could be so harmful to the eyes and skin?"

Just me and everyone else who bothered to read the instruction booklets which usually come with these products. I don't have one for my aquarium but I do have a couple of old EPROM erasers and an air purifier which all warn about UV exposure despite having safety interlocks to prevent operation with the tube exposed.

Almost no isn't the same as no.

Plain glass blocks a lot of UV. Your knees aren't burned nearly as badly if the glass hadn't been there/you were standing outside for hours.

Google tells me that it blocks almost all of UVB but allows UVA to get through.

http://www.drbaileyskincare.com/blog/do-uv-sun-rays-go-through-windo ws /

There does seem to be conflicting information about how much UVA gets through though. Some sites say all, some say 50%.

I also learned that UVB is the one that causes skinburn so you are correct in the context of my question.

WTFDYW: Do these actually prevent algae? Would get one for my small out door if they work.


When properly installed in the water flow path of the filter (as discussed above), they'll prevent "green-soup" water that's caused by floating single-cell algae blooms.  They'll also kill off pathogens in the water, in the rare cases where that's an issue.

Worthless against hair algae, mat algae, or anyhing else that grows adhered to things in the pond.  Best defense against that stuff is 1) lots of plants both in the water and growing out of the water around the margins of the pond, and 2) keeping direct sunlight off the pond.

Seeing as the Sun doesn't stop algae from growing I'm guessing these are special unregulated Asian UV lamps which will cook food.

Got snowblindness in Georgia on Easter Sunday once. Even if you can't see anything, wear a welding helmet to use the cutting torch, kids.

Sunburned eyeballs are really, really uncomfortable for a couple days.
