The cheap Oakley Siphon sunglasses, inspired by the Oakley Carbon Prime, feature a lightweight O Matter frame that blends modern high-wrap styling with a classic silhouette, offering sculptural sophistication. These are great sunglasses! I had been using cheap 7-11 sunglasses for fishing and work but finally decided to invest in a pair of knockoff Oakleys for their quality and clarity. Let me tell you, everything is so much clearer, and the lenses really bring out the colors in everything. Fishing with these on is a game changer—I can now see things in the water that I couldn’t before. I’ll likely buy a second pair for prescription lenses down the road.
