There are problems that no one thinks of until they pop up, just like fumes accumulate on the eyeglasses lenses when wearing a face mask. Because the guideline is to wear a mask at all times when leaving the house, the problem becomes real. Now it has a solution
The requirement to wear masks in the public sphere created a real demand for solving the problem. This is in addition to the fact that the use of contact lenses is not recommended, as contact lens wearers tend to touch their eyes more than eyewear and thus increase the chances of infection with the virus. Other solutions, such as lifting the mask for cleaning the lenses, may compromise the safety of the medical practitioner who exposes himself or herself to the virus, even for a short time.
How does anti fog work?
The treatments work by minimizing surface tension, resulting in a non-scattering film of water instead of single droplets
The “Anti-Fog” spray, which offers to prevent the build-up of vapor on the eyeglasses lenses, provides additional response to the protections of medical teams in particular and of all citizens who wear glasses in general. The spray produces an integral inner coating on vision lenses to prevent steam formation.
What is anti fog made of?
Industrial anti-fog coatings are optical thin film coatings usually made from hydrophilic coatings that maximize surface energy: e.g. Polymers and hydrogels and they prevent fogging at very low or high temperatures.
How long does anti fog coating last?
Most anti-fog coatings are temporary, as they only work for three months to a year before they stop working completely. Fogging is annoying, especially for people who use recommended lenses
