Do burning things with magnifying glasses damage your eyes?

No. I did it all the time as a kid, and I see fine, besides nearsightedness.

Many materials in dust form can burn your eyes. Calcium sulfate is plaster of Paris, and when it is moistened, such as in your eyes, it hydrates and gives off heat energy, hence the extra burning. This is called an exothermic reaction.

I'd say no. As the drops dilate your pupils, it will leave you unable to focus properly on any objects. You won't be able to see properly after the procedure until the effect of the drops has worn off, everything will be really really blurry.\n\nHowever, depending on how long the drops take to wear off, you may be able to drive after a couple of hours. So if you can go to a cafe for a drink, or do some easy shopping or something to pass the time until then, you may be able to drive.\n\nRing your optician and ask their advice, they will be able to tell you how long the drops take to wear off.

It depends on the intensity of the flash. Have you ever looked at the flame/flash of someone who is welding? The light is very bright and can produce spots in front of your eyes. Have you noticed that the people who are doing the welding are wearing dark goggles or a mask with a dark lens?  That's the reason. They don't want to get welder's burn or flash burn of the eyes. Disjointed sight can last a long while if you are close enough to a bright enough light of any type.

if you have been rubbing your eyes, almost any drop will make them burn when you put it in.  They all really consist of the same ingredients so put it in, squeeze something tight during the burn and then go about your day.  Try putting the drops in as soon as they start to bother you and the burn may be less.

i wouldnt worry about that.  what you should be concerned with is the toxic gasses coming from the burning plastic.  you can literaly die from some of the more exotic stuff you could accidentally breathe in.

You can open them...\nYou'll see blurry though. Salty water itches and burns a bit.\nBut for a little while you'll see a few things (a very llittle while)\n\nGoodluck!

No. You may see a distorted image, but it is not what the person themselves see without glasses.\n\nI'm high-myopic, -9 to -10, and people would look through my glasses and say "wow, do you really see like that?"\n\nI'd have to tell them "no. That's the correction to my vision, not the way I see without glasses."\n\nOne day, by accident, I found common lenses that would let me show other people what my uncorrected vision was like. I picked up a double pocket magnifying glass. It had two ordinary magnifying lenses in it that could be swung out one at a time or both at once to increase magnification. With both lenses out, while I was wearing my glasses, I looked through the magnifiers at a distant wall. I realized that what I was seeing was the same as I would see without any glasses at all! \n\nSince then I've had a way to show people roughly what I see like without glasses. For extreme nearsightedness, put two standard magnifying glasses together and hold them to one eye about where normal eyeglasses would sit and look at something distant. If you're vision is in the normal range, you'll approximate my uncorrected vision.\n\nIn general, I believe, if you want to know what it is like to see what another sees *without* their glasses, and your vision is withing normal limits, you would need another pair of glasses made to the *opposite* prescription. Theirs corrects the prescribed amount, your vision would have to be distorted that same amount.\n\nMy trick wouldn't show you how someone farsighted sees. You'd need a different type of lens. In general, correction for nearsightedness like I've got is done with lenses that make distant objects smaller and darker. Correction for people with farsightedness is accomplished with lenses that are more like magnifying lenses.\n\nThis doesn't even deal with other problems with the eye, such as astigmatism or presbyopia.\n\nThere's one plus to my vision that most people don't realize -- when I take my glasses off, I see magnified up to a distance of about four inches. I can literally read engraving on the head of a pin.\n\nThen there's what Spider Robinson said: "People with glasses are lucky. We can see stars on rainy nights."

You can fry your retinas.

Squinting serves two purposes: it improves eyesight by defining objects that are out of focus, and it cuts down on brightness from sources of glare, however, squinting halves the normal number of times a person blinks per minute, which could lead to  eye strain, irritation, tearing and an irritating but treatable condition called dry eye.

your eyes cannot handle the amount of impurities in the waters of the ocean or pool... what make your eyes burn is them trying to clean all that stuff up.. Its ok if you do it for a little bit, because the eyes are one of the fastest healing tissues in the body.. but you dont want to do it often enough that you damage the tissue permanently

Radiation from the TV destroys the cone and rod cells of your retina. If you are destroying more cells than the body can create, you are gradually destroying your eyesight.

You could use VISINE eye drops for redness...caused by reading too much, etc.

absolutely! If you suffer from high temperatures exceeding 104^F for more than a few hours, you should seek imediate treatment. Your eyes are not the only organs at risk.

No, no, no!  That's a myth!  Gazing at anything too closely might cause eye strain, but only if a person is far-sighted and has a hard time seeing items up close.  Even if the eyes are strained, that's a very temporary condition, and more of an annoyance than a health problem.

Maybe get it checked out by an optician.  If your pupils are dilated in strong sunlight you could be getting damage to the inside oif the eye...;

NO. JUST DO IT UNTIL YOU NEED GLASSES.\nYOU WILL BE FINE.
