I wear bifocal prescription glasses and was wondering if past trekkers could please comment on whether they experienced any problems going downhill with them? Also fogging up – a remedy?Cheers
Hi Lorna
I had nothing but problems with mine in fact I went one day without them despite the strain it put on my eyes found it easier without them
My glasses with progressive lenses were a real problem for me and with the rain continually fogging up made it even worse. I took some antifog spray that did not work at all.
By far my worse problem were the lenses themselves as you wear bifocals you will know what I mean walking up a flight of stairs, for me no problem, but walking down the same stairs wearing bifocals not the same for me a real problem at times doing so.
You will have to look where you place your foot each and just about every step of the way, if you want to look around stop dont do so whilst on the move, watching every step means that you are looking down all the way and bifocals are not good at this I have found.
When I go next time I will get a standard pair of glasses, NON Bifolcal, to wear specially for the trek.
I have no answer or fix for the problem especially with the real down hill problem.
Good Luck with yours
BrianGreat. I'm doomed then. I don't have bi-focals, but I am very short sighted. Let's just say if a stop sign wasn't red and ocangular in shape, I wouldn't know that it says 'Stop' as I wouldn't have a hope in heck reading the word 'Stop' if I was standing right under it without my glasses
P.S. I hear that car window spray stuff works great on prescription glasses re; de-fogging/de-misting, but haven't tried it myself yet…
I'm just as short sighted as you Fluppy!! My reading glasses have been progressive lenses for years but it's only in the past couple of years that I've added the bifocal section to my prescription sunglasses so that i can also read in them without difficulty.
In fact it's one of these old pairs ( the latest ones without bifocals) that I always use to run in, mainly because they're the old fashioned type with wire frames and the little nose pad bits – as opposed to all the newer styles which are all plastic and tend to slide on ones nose at the first hint of perspiration. They're great, as long as I don't want to read a book. i'm going to wear these to trek and take my other bifocals for night use, reading etc.
Whilst you experienced problems with fogging Brian I'm sure I read another reply somewhere on this site months ago that said they thought the anti-fog stuff worked well. Could you tell us what brand of product you used.. so we can avoid it like the plague.
Hi Lorna
Sorry cannot remember the name of the product that I used I tossed it in the bin when I got to Kokoda as it was a waste of time.
I have been told, but could not find it, there is a product called Anti Fog Stick I asked around but could not track it down.
What did help at times on my porter Brendan's advice I rolled back the front of my hat to allow more air to circulate around the glasses this did help a little.
I guess my body got quite hot particularly around the head and with the colder rain on the front of the lenses helped create fog on the inside of them. Much like a car window but we have no demister like a car.
Please if you find something and after testing you find it really works please do let me know.

Next time i'm anywhere near the shops ( end of the month) I'll buy as many different types of anti-fog as i can find. Then on a really humid day I'll road test them by firstly going into the coolroom for a few minutes and then out into the humidity. This always makes my glasses fog!! Will keep you posted.
My optometrist ordered me a stick called VU-KLEAR fog-off stick. It worked really well for me, but I have to mention that we didn't actually get any rain in the daytime during our trek.
I also wear graduated lenses, and didn't really have any trouble except, as you say Brian, I have to stop before looking around when I'm walking. The biggest problem I had was coming down Imita Ridge – the sweat kept pouring down behind my glasses and blurring my vision. Next time I will wear a sweat band on my head to prevent this. It was only a problem in the lower areas – up in the highlands where the weather was cooler it was fine.
Hi
I will whilst carrying my progressive vison glasses I will certainly be wearing a standard pair when I trek next time.
Thanks for the advice I have found this site am not sure if you can buy direct may try in the next few days.

I am like a little steam train when I get warmed up hence the reason coupled with the rain that my glasses fogged up so much.
If any one tries and can buy this product direct please do let me know.

Hi
Attached is a photo of the Fog-Stick whilst I do not yet have a price it should be available from your local SafetyQuip outlet who are distributors of Vision Sales Pty Ltd Products.

I took the fog off with me and it worked well. Another tip is to take your hat off in the jungle/shade…. it reduces fogging and is also much cooler. Bifocals didn't prove a problem, I just made sure I stopped before taking my eyes off where I was stepping to look around.
I have run out of time to get this stuff. Couldn't find it anywhere. What else is available? Rainex (for cars?)
I'll post you mine Fluppy…. when are you leaving? I don't get a mail truck till the weekend though. I got it from my optometrist.
Lorna – No no! Don't do that – I don't think I'll get it in time! But of course, thank you for your generosity
I leave this coming Sunday at 10am from Brisbane Airport. I will be returning on the 30th of October (taking a night or two extra at the Gateway to decompress and absorb everything before we fly home to Oz). I probably won't be able to post until at least the 2nd of November – as I think I will be sleeping, sleeping and more sleeping. Did I mention I think I will be sleeping for a couple of days?!
