Hello everyone. I've been noticing that my lenses fog up a ton on my Gear VR, and I know many of you have the same problem. I wanted to share my knowledge as far as lens fog.
I've played paintball for quite some time now, and I sweat a ton. I always have (even when I was in shape. Lol). The answer in paintball are lenses called "thermal lenses." These are basically two lenses that are attached with a small air pocket in between. This allows the difference in air temperature to minimize between the first and second pane. This almost completely eliminates fog.
The reason I mention it is with the hopes an oculus employee may check it out. I'm not sure if there would be any distortion, as these are obviously different lenses, but it is an incredible solution, and I truly think every Oculus should be equipped with them. Thanks.
