AR Glasses? How to Make Anti-Fogs Work Even Better
Lots of defogging agents struggle on AR coated glasses, so what's the trick?
First, AR Coatings.
AR coatings are applied at the molecular level to your glasses. These coatings are typically applied in a vacuum (yes like space). The factories then typically fire electrons at metal oxides to evenly disperse the formula into the vacuum evenly coating the lenses. This process is then repeated several times if necessary.
This is a complicated process that if done correctly produces an extremely smooth lawyer of oxides.
However, through the use of your glasses, touching of the coatings, and day to day oxidation of the coatings, we cause imperfections in the coatings. These imperfections are typically visible to the human eye but they exist.
These imperfections also make it more difficult for common fog solutions to grasp the lens surface so when the fogging solution are applied, they very commonly slide off.
These imperfections are what we need to solve that and one of the most common house hold ingredients that can help with this problem is toothpaste. Typical toothpaste can be used to slowly buff out imperfections in the lens coatings.
The application of toothpaste is an art. You do not want to use a toothbrush to apply the paste (sorry about the picture above) instead use your finger. Put a small amount of toothpaste on your finger and slowly and light move in small circles around both sides of your lenses.
After doing several applications, you'll find your anti fog solutions significantly better and this is why we recommend toothpaste to some of our customers who are having a hard time with Brightn Solution sticking to their lenses.
Another option is high grade glass polish. High grade glass polish has been designed with extremely fine abrasive technology to remove oxidative materials for the lens. These solutions act in a similar way to a toothpaste and can be used in a similar way!
