Oakley introduced the M Frame sunglasses in 1989.
The M Frame became known for its wraparound design and interchangeable lens approach. Its continuous lens shape gave athletes broad coverage while preserving the sporty, technical appearance associated with Oakley products.
Oakley developed a strong reputation in performance eyewear, especially among cyclists, runners, and other outdoor athletes. The company’s designs often emphasized impact resistance, optical clarity, and secure fit rather than conventional fashion styling.
The M Frame is sometimes confused with Oakley’s later Jawbone and Radar families. Those models share Oakley’s performance-oriented design language, but the M Frame was the earlier model introduced in 1989. Oakley itself was founded by Jim Jannard in 1975, a fact separate from the M Frame’s launch date.
