Costa

Frequently Asked Questions

• What is Costa’s 580® lens technology and why does it matter for fishing and water sports?

  Costa’s 580® lenses combine high‑efficiency polarization with selective color filtering to reduce glare and boost contrast on the water. They deliver 99.99% polarizing efficiency, block harmful HEV blue light, provide 100% UVA/UVB protection, and are available in 10 tints optimized for different light conditions.
• How do 580G (glass) lenses compare to 580P (polycarbonate/Trivex) lenses?

  580G Lightwave glass prioritizes optical clarity and scratch resistance and is about 20% thinner and 22% lighter than standard polarized glass, making it ideal when visual fidelity matters. 580P (polycarbonate or Trivex) is lighter and more impact resistant, uses the C‑WALL® molecular bond for surface protection, and Trivex is commonly used for prescription lenses.
• Which Costa frame materials and hinge types are best for saltwater use?

  For saltwater environments, Costa’s marine‑grade metals (Monel and titanium) and bio‑based TR‑90 nylon frames are engineered to resist corrosion, and stainless‑steel hinge options (integral, optical spring, and 5‑barrel) help maintain fit in harsh conditions. Hydrolite rubber on temples and nose pads improves grip when wet and C‑WALL® coatings add water, oil, and smudge resistance to lenses.
• Can I get prescription lenses in Costa sunglasses and which lens materials work best for prescriptions?

  Most Costa models can be fitted with prescription lenses across their lens materials; Trivex is frequently specified for prescriptions because it combines lightweight construction with good optical clarity. If you need impact resistance and a lightweight feel choose 580P/Trivex, or select 580G glass when maximum optical clarity is the top priority, and request coatings like C‑WALL® and hydrophobic treatments if available.
• How do I choose the right Costa lens tint and frame fit for bright open‑water fishing versus low‑light or overcast conditions?

  Choose a darker, high‑glare 580 tint for bright open water to cut glare and a lighter, contrast‑enhancing tint from Costa’s 10 options for overcast or low‑light conditions to boost detail and color separation. For fit, pick full‑coverage or wrap styles (like Pro Series designs) for offshore or high‑glare days and smaller lifestyle frames for casual coastal use, and look for Hydrolite nose pads and secure temple designs to keep lenses stable during active pursuits.
