Helmet Visors

Why is UV protection so important to you? Worried about a sunburn in the cockpit? I think the canopy blocks pretty much everything already.

If you look through something tinted dark (sunglasses/visor) your pupils dialate to allow more light through
If the Visor/sunglasses don't allow UV protection then you're allowing an increased amount of UV rays into your eyes than if you were looking through something clear with your pupils constricted.
 
todd said it, that's why I care so much. No UV protection with tint is actually worse for your eyes than no UV protection at all.
 
While I applaud your desire to keep your eyes healthy, I'd keep it in perspective. There's thousands before you who've been "exposed" like you're concerned about, and we all still have working eyes. If you think this is an issue, wait about 2-3 years, and you've been flying in your noisy platform, living in a stateroom w/ a continuous set of fancoils that are rumbling away, and have swallowed what must be at least a gallon of hydraulic/engine/transmission fluid after preflighting everyday. Preventative health becomes more relative then.

It doesn't completely eliminate the glare, just makes it way less annoying. I think that polarization is awesome, and does WAY more good than bad.

Polarization is good!

Guys, you can still see traffic just fine in the T-44 (with polarized windows).

Two questions. Why are those various mechanical fluids in your mouth? :confused: Which one is most delicious? :tongue2_1
 
agreed - solid UV protection, no polarization. Just tested it on one of my helmets (now sitting on my office bookshelf - great conversation starter!)

To get rid of the JP-5 flavored water. My favorite has always been MIL-L-23699 with a hydraulid fluid chaser. :eek:

Constipation has never been a problem on the boat.
 
Question: Whatis the current policy regarding Sunglasses being worn under the helmet??
just curious... cuz I hear it's a no-no even though I've seen pics of old-schoolers sporting their shades under the helmet... I'm willing to bet A4s has done it a few times...

I am not sure who owns this website, but this seems a pretty legit explanation of why not to wear polarized lens:

The only reason they recommend not wearing them is if the canopy/windscreen is already polarized. They confirmed then that polarization is good (since some planes have polarized windscreens, ie. T-44), just not double polarization. So my conclusion from that article is to wear them if you know your canopy is not polarized.

I have been in the Navy now for 9 years so all your "I am an experienced guy and you are a paranoid newbie" talk goes right through me. I have been there, and am always looking to keep myself healthy because of it. Thanks for the tip....

Were you aircrew for those 9 years?

Oh yeah, I agree. I am just saying that 1. It is a better explanation than my first one and 2. It looks like it my be from authoritative source, as opposed to our conjecture.

No, but I have been around 90% of the hazards he was talking about as well as a butt load of others. I am not trying to start a pissing contest with any of you, but I hate guys that make posts like that. I think this thread contains a legitimate concern and if he thinks I shouldn't worry about them yet since I haven't been a pilot for 2-3 years like him, he should just keep it to himself.

Thanks to the rest of you for all the GREAT input.
