These options are Non-Polarized lenses, which are classic sunglasses lenses designed to reduce sunlight glare and protect your eyes.
Suitable for: Everyday outdoor activities such as walking, driving, or general use in bright conditions.

Polarized

Polarized lenses are designed to reduce glare from reflective surfaces, such as water, shiny roads, or other bright surfaces. They filter out specific light reflections, making your vision more comfortable and providing better eye protection.
Suitable for: Activities near water or reflective surfaces, such as fishing, boating, driving, or outdoor sports.

OPz (Optimized Polarized)

OPz lenses are an upgraded version of polarized lenses that solve the issue of traditional polarized lenses making digital screens appear completely dark at certain angles. OPz lenses are optimized for digital screen visibility while still providing the benefits of polarized lenses, making them more user-friendly for digital screen use while wearing sunglasses.
Suitable for: Outdoor activities requiring frequent use of digital screens, such as cycling with GPS devices, hiking with smartwatches, or work-related tasks involving tablets or smartphones.

They are tested to withstand a .15 caliber projectile traveling at 700–725 feet per second, offering impact resistance that is over 7 times stronger than ANSI Z87.1 standards.
Suitable for: Tactical and high-risk activities, such as military or law enforcement operations, shooting sports, or work in hazardous environments.
