The thin temples and rounded cat-eye brow of the Cheetah were first seen in 1988 and had a long run as the signature Smith women's frame. Offered in many of the original frame colors, the lenses have been updated to feature their crystal clear, carbonic TLT lenses.Read more
Smith's carbonic lenses are optically tuned to give you visual comfort while including ANSI Z80.3 standard for impact resistance, water and oil resistant coating, and 100% UV protection.
TLT (Tapered Lens Technology)
When light passes through a medium it refracts, i.e. changes course. If left uncorrected, this refraction can cause visual distortion and eye fatigue. Smith's Tapered Lens Technology straightens out the incoming light rays by progressively tapering the lens from the optical center toward the peripheral view. What this means for you is that you see with 100% accuracy and maximum comfort.
Polarization cuts glare. Glare off of horizontal surfaces like snow, water, and asphalt, decreases depth perception, and reduces visual acuity which causes eye fatigue. Smith precisely aligns the polarized visual layer inside their lenses to filter out 99.9% of this "visual static" for a finely tuned view of the action.
Visible light transmission: 16%, partly cloudy to sunny conditions.
The base curve is the radius of the sphere measured from the back of the lens. Smith features styles with 6,8, and 9 base lens curvature. Models that include 6 base tend to be more flat relative to your face. While 9 base styles provide the maximum amount of wrap around your face and 8 falls in between.
