Polarized Lenses for the Costa Half Moon

The Half Moon thrives in high-glare settings, polarized lenses are essential. Revant polarized lenses filter out harsh horizontal light bouncing off the water, letting you see through glare and into the details. Whether you’re spotting fish, watching the horizon, or just avoiding squinting all day, polarized Half Moon lenses keep your view sharp and strain-free.

Engineered for Life Around Water

From dock to deck, the Half Moon frame is built to take a beating, and Revant lenses are made to match. Every lens is impact-resistant, scratch-resistant, and tested for optical clarity. Whether you’re out in salt spray, harsh sun, or variable conditions, these lenses perform as hard as you do.

  • High Impact Resistance
  • Polarized to Block Glare
  • 100% UV Protection

Not Sure Which Tint is Best?

Conditions change fast on the water. Take our quick lens color quiz to find the right match for where and how you fish. Need performance in bright open water? Go with Ice Blue MirrorShield® or Emerald Green MirrorShield®, both polarized tints engineered to cut glare and boost contrast under full sun.
