lenses are meant to be used in the Smith Optics Knowledge Turbo Fan
model and do not have vents in the lenses.
You can also use the Knowledge OTG Lenses with the
Regulator Venting in the Turbo Fan model. Some customers prefer
this lens because it gives them the flexibility of using the
Regulator Vents when not using the Turbo Fan, or using the fan and
closing the vents.
A revolutionary, micro-porous filter called Porex™ is structured
such that air molecules may pass through the filter while water
molecules cannot. By utilizing this filter, the thermal lens is
allowed to adjust to varying altitudes while preventing moisture
from entering the space between the lenses. This is the world’s
strongest thermal lens barrier.

lens, Smith Optics molds the model number into the snow goggle
frame. Please look just under the right eye of the outside of the
goggle frame for the model number. You might need to reflect light
onto the frame to see it clearly. Some models stamp the model
number near the inside of the nose area. Please call us at

Blue Sensor Mirror lens
From Anonymous of Highland Park, New Jersey on 3/14/2015.
The lens was shipped quickly and had no scratches, smudges, or other blemishes. This is no reflection on ProLens but it would be nice if Smith made it easier to swap lenses for different light conditions. Also, Smith provides no advice about the best way to force the lens under the gasket to minimize the risk of breakage.

This company was an awesome find. I have an older model Smith Turbo C.A.M. goggle which after a wipe-out I broke the lens. I found the replacement lens here but was not 100% sure it was a match. I called the company and they were excellent. I ordered the lens and received in the very next day. Really! As it happens it was shipped from NH and I am in Mass.This is definitely a company I will use again.

With hesitency I ordered replacement lenses and with great success - it worked. The selection was more than expected and the description of each lense was excellant. The best part was the price and the fast service! I've already recommended this site to my ski buddies.
