I brought the glasses to my mouth and hushed heavily on them – in the way you do before wiping them generally. Even with this mask, I was able to breath and talk without fogging my glasses at all. I then tried with a reusable face mask (mine was from Uniqlo) which I’d bought months ago, and wore once before realising it didn’t have a nose-fitting wire and fogged my glasses. I then exclaimed “Wow, no fog!” – an utterance which produced no fog. So it’s possible that while it can deal with the heat and associated steam that come off eyeballs, it can’t cope with hot breath. The verdict: This spray is also designed to be used on sports goggles and snorkelling masks. While the fogging seemed limited to the edges of the lens frames, it was still very noticeable. My glasses still fogged up, but it wasn’t as intense as with bare lenses. Using a different pair of glasses, but the same disposable mask – with nose wire and inverted ear straps – I took some test breaths and spoke. Once it dries, there is a very fine but noticeable film over the lenses, which makes the glasses slightly translucent – the sort of state that would ordinarily prompt you to clean them. After coating both the front and back of each lens to give it the best chance at success, I let the liquid dry without rinsing, as per the instructions.

The verdict: There was slightly less fog compared with untreated glasses, but not enough to stop me being driven insane after 30 seconds. My glasses fogged after taking a few average breaths and speaking some random words to mimic conversation. To test if these wipes work, I wore a disposable mask, with the wire bent snugly around my nose and the loops inverted around my ears (a tip I’d heard reduces fogging). These wipes are easy to apply and the glasses dry quickly, but while they made my lenses look nice and clear, as you’d expect from a cleaning product, the anti-fog results were underwhelming. These also clean your lenses, and unlike the spray and gel, are only designed for eyeglasses. The box contains 20 single-use microfibre wipes – in little sachets, similar to hand cleaners from fast-food restaurants. I was able to pick up a pack of Clearwipe Antifog Lens Cleaners from Chemist Warehouse for $4.49, and they’re widely available elsewhere too.
