Anti-scratch Coating
The reality is that, there is no goggle lens which is 100% scratch proof. It does not matter whether you go for polycarbonate or glass goggle lenses.
It is for this reason that the anti-scratch coating will be a key selling point in the eyewear industry.
This coating makes the surface harder and reduces chances of scratching.
I am sure there is nobody who would wish to buy a lens, which is susceptible to scratches.
This is why you must protect your goggle lenses from scratches at all cost.
Goggle manufacturers may produce lenses with anti-scratch coating on both sides.
Alternatively, some polycarbonate lenses come with an inbuilt anti-scratch coating.
It is upon you to choose one that fits your goggle lens market niche.
So, how can you choose a suitable anti-scratch coating for goggle lens?
Well, there are 5 main procedures for testing the quality of anti-scratch coating and they include:
- Tumble test
- Bayer test
- Eraser test
- Taber test
- Steel wool test
Do not go for an anti-scratch coating whose quality is in doubt.
It may damage the lens of your goggle.
Apart from quality, you can choose from the following grades of anti-scratch coating:
- General use anti-scratch coating whose hardness is >1H
- An upgraded anti-scratch coating that has high hardness of >3H
- Superior anti-scratch coating with a hardness of 8H to 9H
Other options include the thermoformable and optical anti-scratch coating.
The good thing about these anti-scratch coatings for goggles is that you can consolidate them with other technologies. This results in a functional, safe and durable goggle lens.
In short, you cannot just overlook this essential plastic coating technology.
