Smith Optics - Factor Max Sunglasses

Most notably, the advent of polarchromatic lenses (aka lenses that become darker when the light is bright and become more transparent as the light dims) has become common. That feature is desirable in cycling for obvious reasons. Have you ever experienced variable light while riding through the woods?

So, that being said, this particular pair of Smith Factor Max sunglasses were not equipped with the cool new lens technology (Just note that they are available with polarchromatic lenses) but our test model does have some noteworthy attributes like Smith’s standard interchangeable Slider lens options (always a good/affordable bonus) Polarized lenses. Great for reducing glare.

On these Factor’s, I was happy to see that they streamlined the design a bit. One dislike I have always had with the Sliders was the thick plastic frame across the bottom of the lens (to help hold it in place). The Factors frame is minimal and allows much better visibility throughout your field of vision. They feel nice and light and the lenses are still easy to interchange.

The only major problem I have had with these and other Smith Sliders is the fit. It’s really a personal problem but they just don’t seem to fit my face well. The nose pads are just a little too close together so the glasses sit too high on my face, leaving an annoying space for wind and light to enter into the private space created around my eyes by sunglasses. Like I said, it’s a personal problem but I recommend trying them on before buying. In that respect, I would probably opt for the Smith Reactor Max or D-Max models over the Factor because they have adjustable wire nose pads.
