Maui Jim 'OPIO vs. Other Square Polarized Sunglasses
If you're considering the Maui Jim 'OPIO MJ616, you might also be looking at other square-frame options in the Maui Jim lineup. Here's how the 'OPIO compares to similar models in our collection.
'OPIO MJ616 vs. Maui Jim CASTLES MJ728
Both the 'OPIO and the Castles MJ728 feature square frames with Maui Jim's signature PolarizedPlus2 technology. The 'OPIO is specifically designed with SuperThin Glass lenses for the absolute crispest optics, making it ideal for nature lovers and outdoor enthusiasts who prioritize optical clarity. The Castles offers a similar square aesthetic in the $235-$261 range and may be available with different lens material options. If you want the sharpest possible vision and don't mind the slightly heavier glass lenses, the 'OPIO is your choice. If you prefer lighter lens materials or a different frame style variation, explore the Castles.
'OPIO MJ616 vs. Maui Jim RED SANDS MJ432
The Red Sands MJ432 is one of Maui Jim's most popular square frames, priced slightly lower at $199-$240. Both models deliver the same PolarizedPlus2 glare elimination and color enhancement, but the 'OPIO's SuperThin Glass lenses provide superior optical clarity and scratch resistance compared to polymer lens options. The Red Sands may offer a broader range of frame colors and finishes. Choose the 'OPIO if you want the best possible optics and plan to use your sunglasses for activities where visual precision matters—fishing, driving, or hiking. The Red Sands is an excellent alternative if you want a proven design with more style options.
Why Choose the 'OPIO?
The 'OPIO stands out for its SuperThin Glass lenses—if optical clarity is non-negotiable, this is the lens material to choose. The square frame with saddle-style bridge and rubberized grip points makes it exceptionally comfortable for all-day wear, and the four lens color options let you optimize for your specific light conditions. It's the versatile square frame for anyone who spends serious time outdoors and wants to see the world in vivid, glare-free detail.
