The Oakley HSTN Rx A 8139A eyeglasses represent a fresh take on prescription eyewear, drawing inspiration from street culture and Oakley's performance legacy. The HSTN name references Houston Street in New York City, bringing a progressive design sensibility to everyday prescription frames.
Design Heritage Meets Modern Street Style
The HSTN Rx A features striking modernized round lenses that balance classic appeal with contemporary edge. What sets this frame apart is its distinctive trigger stem temple design—a direct homage to Oakley's iconic 1980s Razor Blade sunglasses. This angular temple profile, which drops sharply before curving over the ear, adds both visual interest and secure retention while creating a bold silhouette that stands out from conventional prescription frames.
The low bridge fit (the "A" designation) is engineered specifically for faces with lower nose bridges and higher cheekbones. The lenses sit higher and wider than standard fit versions, preventing the common issues of frames sliding down, sitting too low, or pressing uncomfortably on temples and cheeks. This makes the HSTN Rx A an excellent choice if traditional frames never quite fit right.
Built for All-Day Comfort
Oakley constructs the HSTN Rx A from lightweight O Matter™, a proprietary nylon-based material that's 25% lighter than traditional acetate and twice as strong. The injection-molded thermoplastic resists shifting and deforming over time, while its controlled flexibility improves impact safety—important whether you're skating, cycling, or just navigating daily life. Unobtainium® nosepads provide a no-slip grip that actually increases with moisture, keeping the frames stable during activity.
The full-rim construction accommodates prescription lenses across a wide range of powers, and each pair can be fitted with Oakley Authentic Prescription lenses that come laser-etched with the ellipse logo for proof of authenticity. Available in 11 colors ranging from matte black and clear to olive ink and transparent finishes, the HSTN Rx A works equally well in the skate park, the office, or anywhere you need prescription eyewear with distinctive style.
With a 52mm lens width, 21mm bridge, and 140mm temples, the HSTN Rx A delivers a medium fit that suits a wide range of face shapes. It's gender-neutral by design, reflecting the inclusive ethos of the street culture that inspired it.

Frequently Asked Questions
What does the 'A' mean in Oakley HSTN Rx A 8139A?
The 'A' designation indicates this is a low bridge fit frame, engineered for faces with lower nose bridges and higher cheekbones. The lenses are cut higher and wider than the standard HSTN Rx (OX8139) to prevent the frame from sliding down your nose or sitting too low. If traditional eyeglasses tend to press on your temples or cheeks, the low bridge fit version will provide a more comfortable, secure fit.
Can I get prescription lenses in the Oakley HSTN Rx A eyeglasses?
Yes, the HSTN Rx A 8139A is prescription-ready and designed specifically for prescription lenses. The frame accommodates 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 and authenticity.
What is the trigger stem design on the HSTN eyeglasses?
The trigger stem is a distinctive temple design that features a sharp downward angle before curving over the ear. It's a modernized version of the temple style from Oakley's iconic 1980s Razor Blade sunglasses. This design provides both visual heritage appeal and functional retention, helping keep the frames secure during active wear while adding a unique street-inspired aesthetic.
What is O Matter material and why does Oakley use it?
O Matter is Oakley's proprietary nylon-based thermoplastic frame material. It's 25% lighter than traditional acetate and twice as strong, with controlled flexibility that improves impact resistance. The material resists heat, cold, UV radiation, and chemical exposure without becoming brittle or deforming over time, making it ideal for all-day comfort and durability in both everyday and active use.
Who designed the Oakley HSTN frame?
The HSTN was created through Oakley's collaboration with skate icon Eric Koston and renowned photographer Atiba Jefferson as part of the Sentio project. The design is inspired by Houston Street in New York City and reflects priorities of heritage, authenticity, and street culture. The eyeglass version (HSTN Rx A) maintains the same progressive design and heritage features as the original sunglass introduced in 2021.
What face shape works best with the Oakley HSTN Rx A round frames?
The HSTN Rx A's modernized round lens shape works well on angular face shapes like square, rectangular, and diamond faces, as the curved lines soften strong jawlines and cheekbones. The gender-neutral design with a 52mm lens width provides medium coverage that suits a wide range of face sizes. The low bridge fit is specifically engineered for those with lower nose bridges and higher cheekbones, common in Asian and some other facial structures.

Oakley HSTN Rx A vs. Holbrook Rx vs. Plank 2.0: Which Prescription Frame Is Right for You?
Choosing between Oakley's lifestyle prescription frames comes down to face shape, fit needs, and personal style. The HSTN Rx A 8139A stands out for its street culture heritage and low bridge fit engineering, but it's not the only option worth considering.
HSTN Rx A: Best for Round Lenses and Low Bridge Fit
The HSTN Rx A delivers modernized round lenses with a trigger stem design inspired by Oakley's 1980s Razor Blade heritage. Created in collaboration with Eric Koston and Atiba Jefferson, it brings authentic street style to prescription eyewear. The low bridge fit is the key differentiator—if standard frames slide down your nose or press on your cheeks, the HSTN Rx A's higher, wider lens cut solves that problem. At $187–$208, you're paying for cultural significance and specialized fit engineering.
Holbrook Rx 8156: The Budget-Friendly Classic
The Holbrook Rx offers Oakley's most iconic square/rectangular shape at a lower price ($92.13–$187). Inspired by the best-selling Holbrook sunglasses, it suits round and oval faces better than the HSTN's round lenses. However, it only comes in standard bridge fit, so those needing low bridge accommodation should look elsewhere. If you want proven Oakley style without the premium price or specialized fit, the Holbrook Rx is hard to beat.
Plank 2.0 8081: Understated and Versatile
The Plank 2.0 ($95.33–$187) offers a more subtle rectangular design for those who prefer low-profile frames. It's made from the same lightweight O Matter material as the HSTN but lacks the trigger stem heritage and cultural backstory. Choose the Plank 2.0 if you want Oakley quality and comfort in a universally flattering shape that doesn't make a bold statement.
Our recommendation: If you need low bridge fit or love the street-inspired round lens aesthetic, the HSTN Rx A is worth the investment. For traditional fit and budget-conscious buyers, the Holbrook Rx delivers iconic Oakley style at a better price. The Plank 2.0 splits the difference for those wanting understated versatility.
