I always like seeing what products are around using nanotechnology. This one caught my eye - laser safety goggles with an anti-fog insert which avoids fogging even “under extreme conditions”. It even claims you could take them jogging although I think one might look a bit silly running around in safety goggles!
The anti-fog insert is a plastic sheet coated with nanoparticles that absorbs humidity and avoids saturation of the air with water vapour. Consequently, a sequestration of water and therewith a fogging of the goggle is impossible.
I wonder if these inserts would work on normal glasses? I always have trouble when opening the hot oven as my glasses fog up and I can’t see. This makes life a little dangerous especially when carrying a hot roast! Perhaps it might be easier to make glass lenses incorporating this feature - may be there are some already out there? Another great feature would be lenses that repelled water as it is a little difficult to see in the rain - guess I don’t ask for much!
