The Masa sunglasses feature a simple yet effective design: a sleek black frame paired with polarized lenses ideal for sight fishing, wading, and days spent by the water. Polarflite lenses are suitable for the most common uses, with a brown tint for bright conditions and a yellow tint that offers better visibility when the sky clouds over. The amber tint enhances contrast when light becomes less direct. Brown Mirrorflite provides additional filtering for very bright days, while PhotoCarbon darkens in response to UV light and uses a lighter, impact-resistant polycarbonate. The choice therefore depends primarily on the prevailing light conditions and the level of protection desired.
