Surf Sunglasses Ventilation to Prevent Fogging

Surf Sunglasses Fogging

There is no point in wearing water sprots sunglasses if you cannot see out of them - it can be a real nightmare if your surf sunglasses lenses fog up! In tropical waters, fogging is not much of an issue but when there is a huge temperature difference between your face and the water (which chills the lenses) fogging can be problematic.

Ventilation Is The Best Way to Minimize Fogging

If your surf sunglasses are well ventilated they will fog much less. Proper ventilation allows the lens and air temperatures to equalize quickly. When the lens returns to air temperature fogging disappears.

Different models use different techniques to increase ventilation. Many surf sunglasses, like the Cumbuco, have holes in the frames to promote ventilation. This has limited effect but is better than nothing.

The Tierra del Fuego has a very special design. The foam padding sits on a hard plastic backing with many ribs and channels. The ribs rest against the frame leaving a plethora of channels for air and water to flow through. This is an innovative and effective approach to ventilation.

The Mauricio successfully reduces fogging by attaching the lens only to the top of the frame and leaving the bottom of the lens completely open. This works really great for people with small cheek bones. If you have large cheeks then you may block the area where air should flow through.
