The Prospect appears deceptively simple, striking a unique balance between lens size, temple weight, and precision fit. Rest assured, these frames are an all day, everyday style for the modern outdoor warrior. The ChromaPop Polarized carbonic TLT polycarbonate lenses offer 100% UV protection and reduce 99% of visible glare from water, snow and sand for increased visual acuity and decreased eye strain. A combination of 8-base-curve lenses; (the higher the number the more curved the lens)  and Hydrophilic Megol nasal pieces and temple ends on the Prospect make for a more reliable grip during activities. Frames are made from bio-plastic Rislan Clear (derived from non-GMO castor seeds) for a resilient, durable and consistent fit. Smith branding on both temples.
