use eye protection around your lights

Google 'blue light harmful to eyes', there are tons of studies about this. It is more relevant to aquariums that use a lot of blue light.

Yes, you're right- it is common knowledge that UV light is bad for the eyes. But, on this being more relevant to aquarium lighting, I'm going to have to disagree. Grow lights these days are really bright, and people should be aware that there are possible safety issues. I'm not saying that you should wear a welding mask to look at your light, but I would definitely consider a cheap pair of sunglasses.

I am not talking about UV light, I am talking about blue light, big difference. Aquarium/reef lighting is more intense than any light used for plants, plus we use a 3:1 ratio of blue to white lights on aquariums, so it it certainly more relevant in the aquarium hobby than any other. Red light doesn't harm the eyes like blue light does. I can stare at my LED grow light all day without feeling eye strain but if I look at my aquarium lights for more than a minute I have issues with my vision.

I have a theory if it's right or not, fuck it, lol.

Blue light will penetrate UV protection and absorb into your retina, that's why its dangerous or how it becomes dangerous. Sunglasses with darker tint aren't necessarily any better than lighter tinted sunglasses.

Here's my theory.....most sunglasses don't do squat for eye protection. Uv maybe, if you dropped some coin. But rarely Blue spectrum blocking [its just tinted glass for $3]. I have used sherpa mountaineering glasses in the past and now can't remember the damn brand name, but when I remember it I will drop it.

This brand was legit, kept out some IR I believe as well, mainly because the gist is, if you are mountaineering you are north or south of the equator and higher in the atmosphere where blue light will predominate?

At least it's a good one in theory! I think there is some truth in there. Discuss.

Those welding goggles seem pretty dark, is it just the blue spectrum and UV that we need to worry about cause I think that can be handled with yellow glasses like these http://www.amazon.com/Uvex-S3202-Genesis-Ultra-Dura-Hardcoat/product-reviews/B000K1JH1M/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1 . I guess maybe the green is providing IR protection that isn't provided by yellow?

I'm pretty concerned about this because I see green and feel kinda weird for a few minutes when I come out of my led grow room and I know I have the beginnings of a cataract in one of my eyes. Not sure why there isn't better information about leds and protective eye wear on the net - my lights came with warnings about eye damage but no suggestions on mitigating that damage.

You think blue LED's are more harmful than the sun? People go out in the sun with no sunglasses all the time...

You all need to start growing different strains different strains definetly some paranoia in there rofl.I agree with beefbisqut. These leds have squat on the sun irritating maybe blinding ill believe it when i don't see it our eyes are resilliant i never wear sunglasses and im satisfied with my 20/20. I think the light could effect your eyes if you are lacking in vitamins that keep your eyes healthy and strong skip the flippin weilding googles and invest in some carrots or retina multi vitsmins..

Remember safety first when you're driving in the evening.... Cars are using LED headlamps! :D

Absolutely.. blue LEDs are MUCH more harmful than the sun in regards to your eyes. Not even questionable.

Edit: And 'blue' headlights are banned in the US, Canada, Europe, and Japan for the same reasoning.. it is a danger to other drivers on the road because it affects how vision reacts at night.

Actual blue headlamps are banned; Exon, Halogen, and other 6000-6500k or supposed 12,000k (which is pretty much blue) amps still contain significant amounts of blue light and aren't banned. You can go to the local mall and buy a package of "cool blue" head lamps for about $30. Google "Eurodesignz".

No question blue light, and UV is harmful to your eyes. Those articles you posted state how the blue wavelength is particularily damaging, but most of the time they;re talking about the blue light from the sun or from prolonged expose to LED light from monitors, TV's, etc.

Just like a few minutes outside on a sunny day won't kill your eyes, neither will a couple mins in the tent. But, if I was going to be outside for a long period of time I would rock my shades and likewise if I was going to be in the tent for 30-45 mins or longer.

I still didn't see any evidence that suggests blue LED's are worse than the sun for your eyes.

And prolonged, continuous exposure to this light — from computer monitors, mobile phones and television screens or indoor and outdoor lights — may be enough to damage retinas, she said.

During lengthy exposures of up to 12 hours, toxicity of the retina is known to increase as the light wavelengths grow shorter.

For years now, professionals in the fields of light energy and vision have known about the hazards ultraviolet (UV) light presents to ocular health. We are gradually having longer and more intense exposures to blue light; much of the world of commercial display and industry is lit with cool white fluorescent tubes which emit a strong spike of light in the blue and ultraviolet ranges. Indeed many homes and offices are lit with cool white fluorescent tubes. No one doubts more people are spending time in front of video display terminals (VDTs) which produce blue light. While some people find blue light irritates their eyes or causes headache, most are able to ignore it. Scientists only now are beginning to investigate its long‑term effects and offer some solutions for maintaining ocular health in the presence of blue light.

All of these are regarding long-term affects from things like monitors, and office lighting, not from short exposures to LED's. You can be extra safe by always wearing glasses, but who goes in their tent and stares at their LED panels while they're on?
