Wearing glasses for the first time...what's up with the fog when eating hot food?

I just started wearing glasses for computer tasks and I like to wear them when I'm eating and how the hell do you eat a hot bowl of soup without your glasses foggy up?
Am I late to the party and you all have figured it out..can you let me know your secret?
Foggy in SD..

  1. I remember right after getting my first pair of glasses and baking for the first time...I went to open the hot oven and my glasses immediately fogged up--for a few confusing seconds I thought I'd gone blind!!!
    Anyway, it's been years and I still haven't figured out a way to open the oven without my glasses fogging up at first. I don't have as much trouble with soup, I guess I don't keep my head as close to the heat from the bowl? I, too, would be interested to hear if there is some secret we're missing out on...

      when opening the oven while wearing my glasses I turn my head to the side during the initial rush of hot air.
      never really had a problem eating soup unless I hold the bowl close to my face. then i'm not worried about fog - I hold it there because i'm cold! ;)

    2. use the defroster app on your iPhone.

        *chortle* +1 @Rmis32!! I just knew someone would create an app for that!

        To OP, no solution. Eat further from your food. Take your glasses off (if you can) when entering a warm building. I've never tried the anti-fog stuff.

      2. It's been years but back when I used to wear glasses, we used an anti-fog cleaner.

          A very small drop of baby shampoo wiped on the lens will do the same thing as anti-fogging wipes.
          We use baby shampoo for anti-fogging for scuba diving masks and swim goggles.

          1. re: monku

            I use spit for my diving mask. Wouldn't think about trying that or baby shampoo for my "seeing" glasses.

            I think the underlying problem with fogging is drastic temperature changes. You can't really prevent that.....but someone will think of something!

            1. re: Dee S

              The baby shampoo trick works better than spit and lasts longer.

              You could probably use it to anti-fog the mirror in your bathroom....again a little goes a long way.

              1. re: Dee S

                Yep, I've long used spit for my swim goggles. I'm not sure how other diners would take it if one pulled off one's glasses and did a spit and rub just as their soup is being served. I can see that baby shampoo would work better, but I just typically don't have it around when it comes time to dive in.

              2. re: monku

                My dive instructor taught us to use spit. ;-)

            2. I remember this from when I worked at a plant nursery in high school. Every time I'd walk into a heated greenhouse, my glasses would fog up. In the years since, I've mainly worn contacts (now with reading glasses) and haven't figured out a solution.

              1. I've worn glasses most of my life and have grown so used to the fogging. The times it is most noticeable to me is when I go out into our harsh, cold and exceedingly long winters (6-7 months). We have to really bundle up in -40 temperatures so of course with scarves and such on my glasses always fog up. Then I hold onto my husband's arm which is nice and cozy anyway!

                No solution but I'd love to try that anti-fog cleaner!

                  I worked (for 2 months) at a company that made windshield-wiper fluid, and one of their products was an anti-fog cleaner. I got a free sample and it just streaked my windshield. There may be something different out there for glasses, though.

                  1. re: chefathome

                    Been wearing them for 36 years myself, you get used to it. The worst is when I'm out running and I get the fog plus sweat on them ... ran into a large bush once.

                    Wore contacts for a while but for some reason they would once in a while go back into my eyeball and I would have to dig around the back of my eyeball to try to find the contact ... I think I had one back there for six months once before I found it.

                    Thinking of giving the contacts another try but now I need bifocals so I'll have to do some research into that.

                    1. re: redfish62

                      Ouch - that sounds incredibly uncomfortable! I can't imagine losing a contact round the back of the eyeball (I've never worn them)

                      1. re: redfish62

                        Bifocal contacts are wonderful. One eye sees close and the other eye sees distance. The doc told me it takes a while (like a month) for your brain to do it all correctly, so you can drive and read without turning your head so only one eye sees things, but it didn't take very long at all for me.

                        I never could eat while wearing glasses. Always got food in my face. Still do when I have the glasses on...if I forget to put them on top of my head. The steam thing- hot to cold or cold to hot, is just physics. I grew up back East.

                        1. re: Cathy

                          I have bifocal contacts (or something similar my galss are progressives) and i see equally from BOTH eyes.

                          OP ya juat got to learn to deal or skip the soup course, sorry!

                          been there, done that :) and back in my cycling days i almost rode right into a tree once when my glasses fogged up.

                        3. re: chefathome

                          -40??? Where do you live, the Yukon? Oh, wait, you really do live in Canada so you must mean -40C not -40F? Brr! We were just grumbling on our walk the other day because it was -19C...I could not imagine -40c! The coldest it gets here is -20F which is pretty darn cold when waiting for the bus...brrr

                          Anyhoo, I have not figured out the solution to the fogging situation. Not easy when wearing a balaklava (I don't know how to spell that but it is a head sock). I can say that you should never follow the urge to wipe them, not even with the cloth they give you when you buy them. I've done that so many times thinking "just this once" and now there are little scratches everywhere!

                          I think I'll try the baby shampoo method or just suffer with blindness...

                          1. re: MinkeyMonkey

                            -40F and -40C are exactly the same - very, very cold. But we often have windchill on top of that! Needless to say, I fog up frequently but am used to it.

                            1. re: chefathome

                              I hadn't realized that until I played with the F and C converter. We could use some of those temps to help rid us of our pine beetles but I doubt it will happen.

                              I can't imagine wind chill on top of that!! Our wind chill last night was -23F and that is as low as I want it.

                              Yes, same here. Fogged glasses are just the way it works, no real way to get around it except to get used to it.

                              1. re: MinkeyMonkey

                                Several years ago the temperature dropped to -50 but the windchill was -65 which was exceedingly painful. Your eyelashes become brittle and it is possible to freeze skin in 90 seconds. It is so cold your eyes tear up and the tears instantly freeze. Tires on cars go square which causes "thump, thump, thump". I could go on but that would hijack this thread so will stop complaining.

                                It is surprising our glasses don't shatter with the drastic temp changes! I know they wouldn't but it seems they could! :)

                              2. re: chefathome

                                I hate whoever popularized the wind chill factor. It's like telling someone, "Yes, you only weigh 150, but with THAT gut, it looks like 200." "Sure, your making $80,000, but the way you piss away money, it's equivalent to $30K."

                          2. Beach Chick: Wecome to the wonderful world of glasses! A little bit of Rain-X can help.

                            But take caution while oven cooking while wearing glasses. If your lenses have any special anti-relective or other coatings on them, sticking your face near an open oven can quickly "craze" these coatings. If this happens, the coatings will gradually and unevenly come off, and your glasses will always look a little dirty. Better to have a completely uncoated pair if you do much cooking.

                            1. You take them off until you finish eating the soup.

                              There are some products you can use to keep your glasses from fogging up that work to some extent.

                              I've had the experience of my glasses fogging up when I leave an air-conditioned building into a humid summer day.

                                "You take them off until you finish eating the soup."

                                Yes, and you park them on top of your head before you open the oven for a few seconds.

                              2. If you wear bifocals only the reading lenses will fog.

                                1. My glasses always fog up when I'm draining pasta into the sink. I can never remember to move my head back before the steam attacks.

                                  1. Also, if you've got anything in the oven with a fair amount of liquid in it, when you open the oven door to check on it, your glasses will fog up.

                                    1. beach chick

                                      in short when hot moist air hits your comparatively cool glasses the moisture will condense on the lenses. its just simple physics and there isn't much you can do about it. the same thing can happen if you are in an over chilled room like in the supermarket and walk out into a hot humid summer day.

                                      1. BC

                                        I have never had the hot soup event but encounter the open oven door event often. I have double wall ovens and when I open the top one now I extend my arms as far as possible and then duck under the initial heat blast that comes out of the oven. Once hat passes they do not seem to steam up.

                                        1. Nothing to prevent it, really, since it's just natural condensation. But what I usually do is take my glasses off and blow on them. The warm, moist air from your mouth usually tempers the material on your glasses and gets rid of the condensation.

                                          Or so I believe. There's probably a very complicated scientific explanation to it all.

                                            Be careful about using chemical sprays on your glasses if they have an anti-reflective coating. Doing so can damage the coating. If the fogging up bothers you, just move the glasses up to your forehead or remove them. You'll get used to it after a while.

                                            The problem will be less noticeable, by the way, if your glasses are already warm because the temperature differential isn't as great so there is less condensation.

                                            1. re: taos

                                              Great point! I had been warned not to use those sprays on my lenses as they were coated with anti-reflectives. I wonder if baby shampoo is okay on them? Well, I need new lenses anyway so I'll ask and if they say it is bad for the anti-reflectives, I'll post back.

                                          2. welcome to the party! i've worn glasses for most of the last 25 years - save for a brief unsuccessful attempt at contacts, and a 4-year period after Lasik surgery - and i *still* run into these problems. more often than not i forget to push them onto the top of my head first, but if you *can* remember, do it just before you:
                                            - open the oven door
                                            - drain off a pot of hot liquid (pasta, eggs, potatoes, whatever)
                                            - sit down to eat a steaming bowl of anything
                                            - stand over a steaming pot to stir it on the stove (or remove the lid from a pot on the stove)

                                            i've always been wary of using any chemical products for fear of damaging the coating or lenses...my prescription is pretty darned expensive!

                                              My Rx is expensive, too, so I am very leary about trying anything on my glasses. Glasses fogging up have been such a part of my life I didn't really give it much thought until I read this thread.

                                                i know, i've gotten so used to it by now. fortunately the climate here in Southern California is nice & dry most of the time...back when i lived on the East Coast (particularly in steamy, sultry Atlanta), they fogged up all the time when i left the apartment or got out of the car.
