Heron Ocean Prescription (Rx) model. A unique, polarized version of our Heron range, borrowing functionality from traditional glacier sunglasses by using leather side shields to block out sunlight reflections and glare. Traditional sunglasses, even wraparound ones, often don’t provide enough protection for long, sunny days out at sea. For maximum protection, opt for the Heron Ocean as your go-to sunglasses for ocean activities such as fishing, sailing, and kayaking. Your eyes will notice the difference.

The price includes prescription lenses, tracked express shipping, and a 2-year warranty.
