The Knowledge OTG Lenses are versatile, designed for use with Smith Optics' Turbo Fan model and Regulator Venting system. They offer flexibility for use with or without the Turbo Fan, making them adaptable to varying conditions. The lenses incorporate an advanced micro-porous filter called Porex, which allows air molecules to pass while blocking moisture, ensuring clear vision even at changing altitudes. This technology is a robust thermal lens barrier. It's the perfect choice for maintaining clarity and protection during your mountain adventures.

Smith Porex

To help identify the correct Smith replacement 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 contact Prolens with any questions about lens compatabilty.

    ChromaPop Storm Yellow Flash

    Posted by Anthony Haag on 22nd Jan 2018

    Lens was straight-forward to replace (with care) and worked well in flat light during storms when you really want to be out there! The only way they could be better is if they came with headlights.

    Red Mirror Lens

    Posted by Angel on 27th Dec 2017

    Color is perfect for bright days but the tint is starting to bubble where the fan is located so i’m not if it was just the particular lens or a problem with all of them.... I will probably go with a different goggle system next season.

    Blue Sensor Mirror lens

    Posted by Unknown on 14th Mar 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.

    Excellent Service

    Posted by Scott Silverman on 29th Jan 2014

    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.
