II. Super Hydrophobic/Crazil coating:
The word 'hydrophobic' actually means water resisting or in normal words, something that has a fear of water. In eyeglasses, it’s basically a 20–30-nanometer transparent coating of titanium dioxide that is placed on the surface of the lens. Hydrophobic coatings are not something new as people are making use of this for a long time on their prescription eyeglasses. It is also found on leaves and on the wings of many insects if you’ve ever noticed it. This is a simple reason why a dragonfly can also fly easily when it’s raining due to having the hydrophobic coating.
The answer is “Of course, it does!” This wonderful type of coating works by making a surface of your glass’s lens to repel the water molecules remaining on them, which means that the hydrophobic coating weakens the surface bonding among the water drop and surface of the lens. This lets the water drops to stay away from lens surface as you can see in the image below.
There are many wonderful examples of hydrophobic coatings to your lenses that also work amazingly. So undoubtedly, hydrophobic coatings do work without any hesitation. But since, it is the last layer that is applied to the lenses, but like any other coating, it might get damaged, and the hydrophobic coating may become useless. So, it is significant that you regularly clean the lenses with water to be more effective and keep the chemicals away, as it might destroy the hydrophobic layer applied on your lenses.
