This SR4068 frame keeps the same square plastic build across front and temples, with a 50mm eye size and 140mm temple length matching the rest of the line. Lenses are UV400 polycarbonate, and the tint list for this style runs from everyday greens and browns to mirrored, gradient, and photochromic finishes, giving plenty of choice independent of the frame color.

The regular Havana colorway is a deeper, richer version of the tortoiseshell look than Light Havana, with darker amber and brown tones mottled together instead of a pale wash. It's a more traditional take on the pattern, with enough depth in the color to read as a warm neutral rather than standing out as a statement shade, which suits it to daily wear more than a look built around the frame color itself.
