Smith I/O Goggles with Blackout and Blue Sensor Lenses

The Smith I/O Goggles are the original interchangeable goggle that invented the category. The I/O is now the standard by which all other goggles are measured. The Blackout (10% VLT) is a S3 Category lens with a dark gray base lens tint that cuts glare and reduces eye fatigue in bright, sunny conditions. This model also includes a Blue Sensor Mirror (70% VLT) S1 Category lens with a light rose base lens tint with a multi-layer mirror that maximizes color definition and increases depth perception in varying levels of flat light conditions. All lenses provide 100% protection from harmful UVA/B/C rays.
