I use Finish (dishwashing rinse agent) on my Go Pro and it works pretty well but haven't tried them on sunnies as I don't kite or foil with them.

I would be a bit worried about the chemicals ending up in my eyes

Thanks @Gorgo that's why I asked about an alternative. Had a look at the lip ones and they're crazy expensive... especially if you have as many wipes outs as I do... would be an expensive donation to the ocean haha. Of the stuff you've tried (wax, rainx) which worked best/lasted longest?

Haha hard core. I'll have to give them a go

Any scratch on sunnies can hold water.

new, (or better) no scratches are best, IMO.

I have one pair of non prescription sunglasses and wear them on land and in water. If they don't work on land.., not good enough to use in water.

Any water repellent wears off(and becomes patchy or surfboard wax style (and never ending recoating is required))

Anything that protects my eyes from the sun is better than nothing(optometrist continues to tell me). I have red skin growth across both eyes, starting to affect sight from right eye.

I am 42 years old.

Every year buy 2 or 3 k-mart polaroid wraparound sunnies for around $8 each, drill holes into arms, thread through thick soft rope with a tightener at the back and another rope for the neck (otherwise tie the head rope to the wetsuit zip pull rope). Yep I look like a kook but at least my eyes are protected.

a bit of detergent wash keeps it from fogging and as soon as they are slightly scratched just let them go

you're never going to get the perfect setup so why drop hundreds on expensive sunglasses that will still get scratched or lost, save it for a better kite or board.

If I can put my smallest finger between frame a across whole cheek to noses- the glasses won't fog. (And don't fog if wearing a properly fitted COVID face mask either!)

I avoid glasses with rubber pieces connected to plastic on nose piece. Always no fog but end up loosing the rubber piece and then the plastic pegs that hold the rubber become uncomfortable, and glasses will fog.

Clarke rubber sell $8 or $10 1m pieces of tube that I get 4 or 5 retaining straps out of. I use the green or blue one- it depends on sunglasses arm diameter. Prefer the blue as has less stretch, i adjust so very slight pressure holds sunnies to face but requires two hands to remove. I have never lost a pair of glasses. Can end up round the neck on the rare occasion. Had one pair fall off, must have pulled in 20plus times and been rag dolled the majority, I lost them. 30 mins later happened to find the rubber tube floating, picked it up and to my surprise sunnies were attached. Tube lasts around 3 months before it starts to break down on attachment(stretch) point to sunglasses arms and then I replace tube.

i tried a lot of different tricks to stop glasses fogging over the years. eventually figured out it was mainly sweat/sunscreen running on them that made them fog.

just give them a wipe with a dry cloth before you go out. inside of my t shirt works for me. but dont forget... always wipe your eyebrows/face dry also. even if you dont htink you need to. and never put sunscreen on your forehead.

works for me

I want to add my 2 cents worth and say that I can not remember how many surf sunnies I have lost over the years because of wipeouts etc. and so I just get some nice cheap ones and attach a cord some how (drill hole etc.) and I use anti fog wipes (pack of about 20 from the chemist etc.;-) Oh and I have had the frame arm brake off so look for a strong frame also:-)

The wax based coatings tend to work pretty well. The last batch we got was from a trade supplier, designed for welding masks and face shields etc. Was based on beeswax. Worked pretty good.

It's a little tube, you draw a bit on and then polish it in both sides, good for half a dozen sessions or so before you need to reapply. Used it for snorkel masks and other stuff too.

Be aware with some coatings or chemicals as they can effect the lenses of glasses. I remember years ago a few crew were using rain-x and kept having issues with lenses delaminating, turns out it was causing the coating on the lenses to bubble up and peel away. Turns out it says not to use on plastics on the bottle. Shoulda read the destructions.

Work for a while. Best if you clean glasses first with ipa.
