I kept my helmet hanging on the wall of my safe room for the past 4 months without a lens cap on the 14. Last night I took the setup out and tube was cloudy and has this streak. So I proceeded to use the " Sock Drawer Method" inside a Pelican case. So far 24 hours with no change I can see... I never thought of needing a lens cap when the NOD was off till a few hours off reading, did I just learn the hard way??

One more thing I noticed. The 14 had a small solid blem where the line starts. I cannot find the blem now which I find odd. blem is still there

If it was indeed off, and especially with no battery in it, I don’t think it’s possible it could be light damage

I remember @NVGDude @NVGdude saying something about solar damage on some Anvis a pilot left inside a cockpit without lens caps, so sound like it’s possible

I do leave batteries in my devices because I take them out almost every night.

I had the 14 fall from about 6ft onto wood maybe 3 months ago, but this just showed up last night and it doesn't look like debris to me since its ghosting.

are your lenses scratched or dirty. you'd be surprised how many pilots bring them into my shop with scratched or just dirty lenses. you'd be more surprised if I showed you the crap we find during 6 month inspections that went unnoticed by the user. Like bridges that are cracked 3/4 way through and flexing, but not reported until the 6 month insp

Ive had lens protectors on the front and a filter on the back since purchase. The first thing I did was clean the lens with 99%iso and inspect everything with a magnifier. But good advice, always start with the basics that are easily overlooked.

The technical data I've read says it's possible and that any light exposure to the tube with or without batteries on or off can damage the tube. ymmv.

How do you work on them? Can you use a red light, like a dark room? Or do you have to wear NVGs to work on your NVGs???

Reminds me of solar damage. Were they hanging in a position such that sunlight could fall onto them, even if briefly in the morning, afternoon, or whenever? Was the pinhole cover in place at all times?

Try to power it up with the ocular lens off and see if the streak is present. Since you have it partially disassembled might as well remove the tube and give it a good cleaning on the inside. The fogging maybe from moisture inside of your 14. I had a single strand of hair on my PVS7 that I cleaned multiple times. Turns out it was on the ocular side of the tube that for some reason was hard to dislodge with 99% alcohol and compressed air.

This was my first thought too, at least from the picture. It's pretty easy to figure out of this is the case.

If the hair is in the objective, a pinhole cap should make a visible difference over an open objective.

If it's in the ocular, it should move with head position.

No windows in the safe room only led strip lighting and my workbench lights. I had the wilcox sacrificial on the front so never bothered with a cover... I hope that wasn't a mistake.

I'll give this a shot once I try David's method. I've never disassembled this NOD but I have pulled my pvs7s apart plenty of times.

I had no idea this was possible. I store mine without batteries and with covers on inside a padded pouch in a safe, but still....that’s frightening!

I have been looking at that and it kind of lines up with one of the workbench lights. If that is the case it was an expensive mistake.

Damn sorry to hear that. There’s really nothing to say that helps at all. It’s still worth a shot tearing it down. I’ve dropped a -14 before and it shook loose debris that was inside. It had a more defined shape to its edges though.

Can still be damaged by light sources. I make sure to remove batteries and put blackout caps on when going anywhere if I think it's going to be exposed to any significant amount of light that would otherwise normally damage it when powered on.

All these people running nods on their helmet in broad daylight with no caps/bikini covers baffles me.

Have you seen light damage from this? Curious what it’ll look like. I’m guessing overall darker image like shading across the whole image? Would be good to know when looking at used tubes

I’ve only ever tested it on one or two very minor burn ins with good success. Just depends on how bad/dark the burn is. It’s never turned out perfectly it just diminishes how bad it looks.

I’ve always been told to do the sock drawer trick for a day or longer if you can. Run through multiple batteries. Make sure no light can get to the unit. Maybe @tnvc could comment on it.

A PVS-14 objective, when looking at the sun and brought into focus on a piece of black plastic smokes that plastic very quickly and leaves an obvious molten mark. Extrapolate that to having binos or whatever flipped up on your helmet, running around, and having the objectives catch the sun. Worse yet leave the helmet stationary, like someone's story of NV left in a cockpit.

Easier to diagnose with an ANVIS, we had the exact same damage in both tubes. As I recall, the goggle was left in an A-10, objectives up.

Which means it was powered off. Use blackout caps when not in use people, it's a simple way of avoiding these issues.

that is a pretty massive hole. is that supposed to be some kind of home brew refocusing cover?

all our daytime training caps have a literal pinhole. you don't even notice them when looking at the caps (we use regular "caplugs")

that one in the picture was drilled with a drill bit and didn't even clean up the edges with a knife or anything
