The Oakley HSTN SQ 9533 sunglasses bring bold square geometry to Oakley’s modern lifestyle collection. Introduced as a squared-off evolution of the original HSTN frame from 2021, these sunglasses blend contemporary street style with the performance DNA Oakley built its reputation on.
The HSTN SQ features a distinctive square frame shape with clean, decisive lines that add definition to any face shape. The frame construction uses O-Matter, Oakley’s proprietary injection-molded thermoplastic that delivers exceptional strength-to-weight ratio. This material resists deformation over time and provides all-day comfort even during extended wear. The temples feature a modernized trigger stem design—a direct nod to Oakley’s iconic Razor Blade sunglasses—while the center frame geometry draws inspiration from the SubZero, creating a bridge between Oakley’s past and present.
What sets the HSTN SQ apart visually is its modular color approach. The multi-piece frame construction allows for striking color-block combinations and tone-on-tone finishes across ten different variants, from wild patterns like the leopard-print frame with blue accents to clean beige and white options. Metal accents on the temples add a premium touch, and the iconic Oakley ellipse logo appears on each temple arm.
The HSTN SQ 9533 is available with Oakley’s Prizm lens technology, a spectral tuning system developed over 15 years of research. Unlike standard tinted lenses that simply darken your view, Prizm lenses selectively filter specific wavelengths of light to enhance contrast and reveal details invisible to the naked eye. The technology blocks distracting colors while amplifying the hues that matter most in your environment, resulting in sharper vision and reduced eye fatigue.
Available Prizm options include Prizm Sapphire, Prizm Ruby (both standard and polarized), Prizm 24K Polarized, Prizm Tungsten, Prizm Black Polarized, Prizm Gaming 2.0, and Prizm Bronze. Each lens is made from Plutonite, Oakley’s high-purity optical-grade polycarbonate that blocks 100% of UVA, UVB, UVC, and harmful blue-violet light up to 400nm. Polarized variants add glare-cutting benefits for water, snow, and high-glare environments.
The HSTN SQ 9533 is prescription-ready and accepts Oakley Authentic Prescription lenses across a wide range of powers, including single vision, progressive, and bifocal options. Each authentic Oakley prescription lens comes laser-etched with the ellipse logo on the left lens for proof of quality. Unobtainium nosepads provide a no-slip grip that actually increases with perspiration, keeping the frame securely in place whether you’re commuting, working out, or spending the day outdoors.
The square shape offers medium to large coverage, making it suitable for a wide range of face sizes and shapes. The full-rim construction provides durability and a confident, structured look that works equally well in urban settings and active environments.
