As a glasses wearer, I’ve always struggled with my glasses fogging up/ steaming up on cold days. Whereas as my visor stays clear through the use of a Pinlock, there is no obvious solution for glasses, just a multitude of products to squirt on that claim to stop all misting up. But do they really work? In the name of science, I conducted a mini-experiment to compare some popular products to ascertain which were most effective. These best solutions here should also be equally useful to stop visor steaming up too.
I used a number of old pairs of glasses, which I first cleaned and then applied the various products as per their directions. As a control, one pair was left untreated. I then placed the glasses in the fridge to cool to 5℃, to mimic a ride on a cool winter’s day. First I took the glasses out into the kitchen with a humidity reading of 55%, to see how the lenses misted up (or not). Secondly, I repeated by taking the glasses from the fridge to the hot shower room with a humidity reading of 60% to test a more extreme scenario.
