Do you want to develop a new function goggle lens to skyrocket your business?

You are in the right place.

In this article , you will learn several important goggle lens related technologies to support your new goggle development.

1. Anti-fog Coating Technology

Fog is an annoying natural phenomenon that forms on surfaces of lenses, thereby, causing refraction, loss of light transmission of detraction. As a result, one cannot see clearly through the goggles.

It is for this reason that goggles lenses must have anti-fog coating.

An anti-fog coating is a hydrophilic chemical treatment. It is applied to the inside section of the lens.

Hydrophilic is a “water-loving” whose molecules interact freely with water. The process involves molecular interaction where the hydrophilic substrates reduce the surface tension of water.

As a result, water droplets or moisture spread into a thin transparent film on the goggle lens surface. This allows the maximum amount of light to pass through with minimal distortion.

Hydrophilic is one of the most trusted anti-fog solution in the face wear industry. It is safe, cost effective and environmentally friendly.

In most cases, the goggle lens manufacturers may use either flow or dip coating with either UV or thermo curing techniques being the most common.

However, this alone is not enough. There are a number of tests that an anti-fog goggles lens must pass.

This a critical quality control (QC) for an OEM or any business involved in importing and distributing these lenses. The tests include:

  • EN 168; a mist retardant tests for anti-fog coating.
  • 05/ECE324; for freezing tests
  • ASTM D1003; haze properties test
  • ECE 22.05; diopter property tests

In short, a goggle lens with anti-fog coating that has passed all the above tests is considered suitable for any outdoor activity. Such goggles do not fog even in the most humid conditions.

2. Anti-scratch Technologies

Read two customer review on Amazon first :

“These work pretty well but scratch way way too easily. Bought three lenses and all of them are scratched after just a few uses. I have other lenses that I have had for years and never scratched. I love being able to swap out lenses but might have been better to pony up for the Anon version. They also have a bad chemical smell for the first couple weeks.”

“Worked well for a weekend trip at whiteface. Didn’t fog up at all. Comfortable to wear. Looked dope. Only con was that the lens scratched up very easily. Would have been 5 star review had the lens not scratched up already”

“Bought these for a first time ski trip. Despite the reviews about how they easily scratch I went ahead and bought them. The googles arrived today and much to my surprise they already had a scratch near the nose area. Although it’s a small scratch it’s definitely disappointing to see as these are brand new and out of the box.”

Scratch is one of the biggest problems for goggle lens.

An anti-scratch coating is an essential technology in the goggle lens industry. Goggle lenses with anti-scratch coating can maintain their optical class 1 property for a long period of time.

At the moments, the manufacturing companies have invested in many technologies such thermoformable scratch resistant coating. This coating ensures the surface remains scratch free and it can withstand several days of washing.

Depending on the desired application, an anti-scratch coating may come in the following 5 options:

  • Optical anti-scratch coating
  • General uses anti-scratch coating with hardness >1H
  • Upgraded anti-scratch coating with hardness >3H
  • Superior anti-scratch coating with hardness 8~9H
  • Thermoformable anti-scratch coating

In most cases, most manufacturers may opt for either flow or dip coating technologies. With the most common curing technologies being UV and thermo curing.

The good thing is, you can use the anti-fog technology for goggle lenses for both indoor and outdoor applications. Moreover, it can be consolidated with other technologies such as UV resistant, anti-graffiti, anti-glare, etc.

NOTE: For anti-scratch coating is applied on one side of the goggle lens while the anti-fog on the other side.

All anti-scratch coating for goggle lenses should meet the following quality standards:

  • Bayer tests as per the ASTM F735-81
  • Taber abrasion test as per the ASTMD1044-82
  • Erase abrasion test as per military standard MIL-E12397A
  • Tumble abrasion resistance test
  • Steel wool abrasion resistance test

With all these features, a goggle lens will remain clear for a long period of time.

3. Lens Tinting Technology

OEM and businesses can benefit from many goggle lens tinting technologies available in the market. Lens tints offer different advantages depending on the weather conditions.

Different tints allow only specified amount of light to pass through. Therefore, it is important for the goggle lens manufacturer to determine the degree of visible light transmission (VLT).

The idea behind this technology is to make the goggle lens suitable for different lighting conditions. This gives businesses and OEM clients an opportunity to explore various market conditions, hence, a high chance of increasing market share.

Below are 8 different goggle lens tints:

Type of goggle lens tintFeatures and applications
GreyBlocks the sun while increasing contrast. A perfect choice for blue bird days
Dark brownAllows more light than brown goggle lenses. Improve contrast
OrangeBrings out bumps, protects eye from strong sun and brings our depth perception.
AmberSuitable for foggy and overcast days
GreenA perfect choice for moderate light days and increases contrast
YellowSuitable for foggy and over cast days
RoseIncreases depth perception
ClearSuitable for night conditions

 

Note: A goggle lens may have a specific tint alongside other technologies such as anti-fog and anti-scratch.

4. Photochromic Goggle Lens Technology

Photochromic is a fascinating technology where a goggle lens automatically tints on exposure to ultraviolet radiation. Below is a video showing how a photochromic visor works.

As you can see, the material systematically changes color from clear to tint.

The good part about photochromic technology is that, there is no need to change the goggle lens to suit a specific tint. It automatically tints protecting users from excess ultraviolet radiation.

Obviously, photochromic lens technology does not protect the lens from either fog or scratches. Therefore, they can be used alongside these two goggle lens technologies.

Apart from these, another option is the:

5. Polarized Goggle Lens Technology

Reflection is a major problem for goggle lenses in outdoor application. This makes polarized goggle lens technology a better option here.

Polarized Goggle Lens

Ordinarily, reflection of light takes place at higher intensities, which is normally perpendicular to the surface.  Polarized surfaces cut glare effectively.

This improves visual clarity, contrast and definition. It is also another technology that is popular in this industry.

For instance, Revo goggle lenses provide nearly 99% polarization.

Another technology that is closely related to this is the mirrored lens technology. Mirrored goggle lenses have a coating on the outer surface of the lens.

This reflects a greater amount of light, increasing visual clarity in bright weather conditions.

Conclusion

As you can see, there are many goggle lens technologies that improve performance and reliability of these accessories. It is important that a company adopts a verifiable way to assess the quality and effectiveness of every technology.

Opting for a technology that is cost competitive and guarantees superior optical properties is an integral aspect.

Normally, you can put several functions together to develop a super good goggle lens,they can be with anti fog , anti scratch, UV 400 protection,photochromic, polarized,revo color or even bulletproof . Any function you want , WeeTect can develop for you.
