Could static electricity to the eyeball cause lasting harm? Normally you just jump and swear with a static shock to your finger etc, but I've found two instances on google of pain lasting a few days when someone got a shock on their nose (one in a shop from a perfume bottle they were smelling, and one from a blanket at home). But what if it got your eyeball?

She said that her hearing was hyper-sensitive for weeks after that. Everything was way louder. |

Yes I suspect that it coincided with her ear wax moving about a bit.
I see that those electrical shows are still popular where people use their bodies to draw huge sparks and invite members of the audience to try it. When I was young I used to play with electricity, high voltage in the ranges of thousands of volts but I did do it safely using high value resistors to current limit the shocks you got. In fact it could often only be felt as a tiny burn on the point of the body the spark jumped from. Its the current that does the damage. Not sure health and safety would allow what I did in school these days though. There are some things you can still get to play with very high voltages safely. One used to be called a violet Wand. Basically a tesla coil and you could see the corona around the charged up tip. Back in the early part of the century, people use to pay for electric therapy with this thing which of course tingled as it was passed over parts of the body. I'm not totally sure this was not just a way to get sexual thrills but then I was not around, but similar things are still made. Van der Graff generators Windshurst machines etc, both use the static build up model to create their high voltages and one has to be careful not to add capacitors to them as the discharge from one of those will kill yu if it crosses the heart.

Well the answer is that it depends Normally static at home is not dangerous
as the voltage is very high but the current is low and the duration brief. I'd expect no more damage to the eye than if it got scratched by flying debris or whatever, and I'm sure we have all experienced that. Obviously there are places and nerves that can be affected, and there are lots of nerves in the finger tips and parts of the face, but generally things get back to normal in a few hours. Having been near two lightning strikes I can tell you its not pleasant, but if your friend really had experienced a lightning strike directly to the phone line the phone and her would be toast. No matter how earthed a device is, it cannot cope with the huge current of lightning. In one case I was standing by a building that got hit, and a split second before it happened I felt my hair being pulled and prickled all over. No time to do or say anything. a huge flash and a very very loud bang and I was deaf for about five minutes with an effect like ears full of water for about another ten. You do not want to be that close. The heat I and others felt was quite bad, but luckily none of us were burned but there was a bloody great hole in the roof of the warehouse just next to the door. all the computers and electronic gear were destroyed. The second time I was walking our dog and it hit an Electricity pylon just by where I was standing. Same again from the sound and radiated heat, but no static this time. I blame the tinnitus I get on the first one myself. Not much one can do about it though. So your answer is as I say, it depends, but if its merely like you get off filing cabinets, car doors, vacuum cleaner pipes earthed screws on light switches or duvets, then its unlikely to cause permanent harm, and just be an irritation.

No matter how earthed a device is, it cannot cope with the huge current of lightning. That isn't true. If it was, telephone central offices would be routinely blown up by lightning, so would internet services, computer centers and similar. All have lightning hits on lines that go into the building. All are protected by tiered layers of protection. You can do the same with your house. First thing, if the lightning hit an overhead phone line outside the house, the vast majority of the energy isn't going to make it inside, to her phone, even with no protection. The voltages are so high that arc over occurs. And with tiered surge protection inside, the rest of the surge can be dealt with. |

I once got a bit of grit in my eye that I couldn't dislodge (after DIY plasterboard work I think), it was damn annoying. After 3 days of it becoming increasingly irritating, I went to Specsavers and they washed it out free of charge, and also gave me an eye test free of charge (presumably both in the hope they could sell me expensive specs). But my eyesight was "surprisingly perfect for a 40 year old - more like that of a teenager". I guess I never grew up :-)
I only saw the effects twice - not sure where the lightning came in, but a row of 4 computers in a youth club had their soundcards fried (literally black in places). Apart from short speaker cables to little computer speakers, I'm not sure why the lightning would have gone in that way. The network cards were fine, but then they tend to have surge arrestors (spark gaps) in them. Nothing else on the computers were damaged. The other time was the network card in a computer in someone's house - that could have been the phone line, although he reckoned a small fork of the lightning came THROUGH the house and landed on the phone cable running along the hall (his computer was fairly central in the building).

Take it from me spark gaps where the voltages and currents that are in a lightning strike as mere piffling things, thats why we use a lot of heavy cross section Ally, used to be copper but the scrotes came for that, all in order to shunt these currents around that what we need to protect!... -- Tony Sayer |

Well not much would shield from a full strike, but often you get stray edges/forks of a strike getting through wires into computers, so a spark gap takes that off. If you got the main strike of lightning into your computer, the whole thing would literally explode - just look at trees that were directly hit, they split in two, explosively. |

Some service lines would be fitted with a ground connection in the early GPO days, but I doubt any are now. Most likely there will be a ground at the pole or the cabinet. |

The ground that was disconnected was a wire from the phone box on the house to a pipe, in this case, where a hose bibb was on the side of the house. I have made sure that both the phone and cable boxes are directly connect to my ground rod using a large (about 1/8") copper ground wire. |

In the UK an underground twisted pair wire inside a plastic hose comes right inside the house and terminates in a socket on the inside of a room wall (same size as a lightswitch or power outlet). There's no earthing anywhere, unless it's further back at the exchange or a junction box. |

It could be that they really don't use a ground for underground phone connections. Since there's a separate wire set for each residence, there is less likelihood of faults at a neighbor getting into your wiring. If you have cable TV, is there a ground there? |

I have made sure that both the phone and cable boxes are directly connect to my ground rod using a large (about 1/8") copper ground wire. Not sure what you mean by "phone box on the house". Quite a few phone systems have a phone box on the side of the house where the phone wire coming to the house is terminated and then there is a different cable into the house. Hear its often called a Madison box. https://www.tradezone.com.au/product...ver-22787.html https://www.youtube.com/watch?v=_93TBmmJyZY Its not legally required and I don't have one at my place. I have an underground service and have a conduit that I put in the concrete slab on the ground before the slab was poured. That comes up in the cavity of the 8" concrete block front wall of the house and there is a wall plate with a phone socket on it inside that room and that is where I join the two cables, the one that comes from the pit in the corner of the block of land which has the multipair street cable going thru it down my side of the street and the cable that loops thru the various phone sockets inside the house. We don't have the master socket concept here, the phone sockets are all wired in parallel electrically. In the UK an underground twisted pair wire inside a plastic hose comes right inside the house and terminates in a socket on the inside of a room wall (same size as a lightswitch or power outlet). So is mine. There's no earthing anywhere, We do sometimes have a lightning arrestor that can be installed in the madison box, normally only seen with overhead phone lines and normally only used in very lightning prone areas. They are essentially an spark gap type thing from the phone lines to the earth which has to be run to the madison box. unless it's further back at the exchange There is that protection back at the exchange or the RIM or CMUX. or a junction box. There are pillars here where the various multipair cables in the distribution area join the much bigger multipair cables that go back to the exchange, RIM or CMUX. https://say.telstra.com.au/res/image...001/Pillar.jpg These don't have lightning arrestors normally. |

Could static electricity to the eyeball cause lasting harm? Unlikely. Don't think it ever produces a sore or anything with the normal sort of static that you are likely to get.

But what if it got your eyeball? Should be fine. |

Bro when I was a kid I was playing on the trampoline with my brother; we had socks on and happened to get shocked in the eye. Ended up popping a blood vessel and it hurt for almost a week to blink or move around
