Probably a dumb question. But, it just came to me. Are there any goggles that make it safe to look at the sun? I'm not talking about wooden blocks! :P I'm talking about something you can actually look directly at the sun safely for several minutes at a time without eye damage. You know for like looking at an eclipse or whatever.
 





yea its called a welding helmet lol or you can get a sun filter for a telescope
but a welding helmet does work i mean you cant really see much looks like a round light ?????

Yeah, that would work. But the sun doesn't just emit light, don't forget about your X-ray protection, Gamma ray protection and all of the other ray protection!

I think you would be better off with the block of wood, if you want to stare at the sun. ::)
 
you can use welders goggles but they should be 14 or higher. And you cant see any detail but it still looks prety good. You can buy film off ebay.

you can cut it up and make some glasses or put it on the aperature of your telescope to see sunspots (thats all though, no flares). if it gets cracked throw it out... and if you try this make sure it WON'T fall off. :) 8-)
 
Solar filters ;D
like baarder filters. I used that to observe the total solar eclipse.
 
I believe aluminum foil is sufficient protection, but don't quote me on that.
 
You can use the pinhole technique. Cut a piece of opaque material and drill a small hole in the center. This will be for all intents and purposes the "lens". Then take a piece of white poster board and place it a distance away from the pinhole. Line it all up with the sun and you should get an image of the sun's disc on the poster board through the pinhole. You should be able to see sunspots on the sun with this technique. You may need to enclose your apparatus to shield it.

Ummm, looking in the direction of the sun isn't really going to change the amount of x-rays and gamma rays you get from the sun.  You skin won't stop gamma rays, they'll do cell damage and burn you either way.  Your body won't do a lot to stop x-rays either, doctors send x-rays through your body to take pictures of your bones, and that wouldn't be very hepful if your body was actually protected from x-rays.  To shield for gamma rays and x-rays, you're generally going to be thinking more on the level of lead than plastic glasses or goggles.  Leaded glass maybe for x-rays.  

And the sun doesn't really produce many x-rays or gamma rays, thankfully, at least none that are getting to the ground in large numbers.  The sun's emissions that we get, and are what we have to worry about, are pretty much all in the UV to IR range.
