The Smith Polarized Folsom sunglasses feature a strong, angular design and outstanding performance in a lightweight frame. The Folsom sports hydrophilic Megol rubber nosepads that provide tenacious grip and become tackier when wet for reliable fit even during exercise. Polarized Carbonic lenses provide the superior optical quality you've come to expect from Smith. The polarization reduces 99% of reflected glare, which enhances visual acuity and reduces eye fatigue. Folsoms offer 100% protection against UVA and UVB rays.
