* Different Size and Shape: Oakley lenses are designed to fit specific frame models. Fake frames, even if they look similar, likely won't have the correct dimensions or shape for the lens to fit securely.
* Lens Mounting System: Oakley uses proprietary lens mounting systems, like their "O Matter" frame material and "Unobtainium" nose pads, which are designed to work together. Fake frames will not have these features, so the lenses will not attach properly.
* Warranty and Safety: Real Oakley lenses come with a warranty and meet safety standards for UV protection and impact resistance. Fake lenses may not offer the same protection, putting your eyes at risk.
In short: Using real Oakley lenses with fake frames is not recommended due to potential fit issues, lack of warranty, and safety concerns.
If you're looking for Oakley sunglasses, it's best to buy them from authorized retailers to ensure you're getting authentic products.
