The Fogging Problem and the Search for a Solution
Year-round cycling in various weather conditions led to a persistent problem with my sunglasses fogging up, especially in cold weather. This issue prompted my search for a solution, specifically ski goggles known for their anti-fog properties.

I considered two approaches: ski goggles with interchangeable lenses (mirroring my sunglasses) or ski goggles designed to fit over my existing glasses (OTG). The latter seemed more practical, offering a simpler solution.

Smith Knowledge OTG: Fit and Comfort
The Smith Knowledge OTG goggles, designed to be worn over glasses, proved comfortable over my sunglasses and didn't interfere with my bike helmet. The fit was snug and secure.

However, wearing them without my sunglasses underneath resulted in uncomfortable pressure on my nose bridge. This highlights their specific design for use over existing eyewear.

Performance: Fogging and Functionality
The goggles themselves performed admirably in preventing fogging, regardless of whether sunglasses were worn underneath. However, the core problem persisted: my sunglasses fogged up even more when worn under the OTG goggles.

Despite adjustments and experimenting with the vents, the fogging issue remained. This significantly undermined the primary reason for purchasing these goggles.

Conclusion and Alternatives
Ultimately, the Smith Knowledge OTG goggles failed to deliver on their intended purpose of preventing sunglasses fogging. Due to this shortcoming, I returned them.

For those with prescription glasses, finding a suitable solution might require exploring different types of ski goggles, possibly those with interchangeable lenses, or investigating prescription inserts. My solution will be to remove my sunglasses when stationary to prevent fogging.
