The Oakley Barrelhouse 0.5 3174 Eyeglasses bring a refined, architectural approach to prescription eyewear. Built from lightweight C-5 alloy—a proprietary blend of five metal compounds—these semi-rimless frames balance professional style with the durability Oakley is known for. The raised nose bridge and clean temple lines create a look that's sharp without being overstated, making them equally at home in the office or on the weekend.
Built for Comfort and All-Day Wear
The semi-rimless design keeps weight down while the integrated spring hinges flex to fit comfortably without pressure points. Adjustable air cushion nosepads let you dial in the perfect fit, and Unobtainium earsocks provide a secure, no-slip grip that actually increases when you sweat. Reviewers consistently mention the comfort factor—one customer noted the spring arms "hold well and avoid problems with ears of unequal height."
These frames are prescription-ready and work well with progressive lenses. The 53mm lens width and 31mm vertical height provide enough space for the progressive corridor, and customers report excellent results even with higher prescriptions. One reviewer specifically called out how "the lens size is just large enough for progressive bifocals" while high-index lenses stayed "nicely thin at -5.50."
A Smarter Alternative to Bulkier Frames
The rectangle shape suits square and heart-shaped faces, and the semi-rimless construction offers what one customer described as "a smart-looking hybrid between full-frame strength and rimless minimalism." Available in multiple finishes including Matte Black, Gunmetal, Pewter, and Blue, the Barrelhouse 0.5 delivers a cleaner, more sophisticated look than Oakley's sportier full-rim models.
"The Barrelhouse was the remedy. These look good and fit very well." — FramesDirect customer review
The C-5 alloy frame material combines toughness with flexibility—it bends to absorb impact and springs back into shape. Temple length is 139mm, bridge width is 18mm, and the frame is available in both 51mm and 53mm lens widths. Each pair ships with a protective carrying case.

Everything was as promised and arrived quickly!
When I received my glasses the right lenses was the wrong prescription. The glasses have been set back ad I am waiting on the resolution.
So here's the deal. The Army gave me glasses that do the same thing but they're a special kind of fugly. I needed glasses that I could wear in public that would withstand a certain amount of rough treatment that's inherent with the profession. Oakley wins. Designer Optics was able to beat the OakleySI price, so they also win. Plus I can see better.

Frequently Asked Questions
Are the Oakley Barrelhouse 0.5 3174 frames compatible with progressive lenses?
Yes, the Barrelhouse 0.5 works very well with progressive lenses. The 31mm lens height provides sufficient vertical space for the progressive corridor, and the semi-rimless design is stable enough to maintain proper lens alignment. Multiple customers have successfully used these frames with progressive bifocals, including higher prescriptions up to -5.50.
What is C-5 alloy and why does Oakley use it?
C-5 alloy is Oakley's proprietary blend of five metal compounds designed to combine toughness with flexibility. It's lightweight like titanium but bends easily to absorb impact and springs back into shape, making it ideal for durable, comfortable frames. The material competes with titanium for weight and scratch resistance while keeping costs more reasonable.
How do the Barrelhouse 0.5 frames fit compared to other Oakley eyeglasses?
The Barrelhouse 0.5 has a more refined, minimalist fit compared to Oakley's sportier models. It features a raised nose bridge, adjustable air cushion nosepads, and integrated spring hinges that adapt to different head shapes. The semi-rimless design is lighter and less bulky than full-rim models like the Airdrop, offering a more professional appearance.
What are Unobtainium earsocks and do they really work?
Unobtainium is Oakley's proprietary rubber material used on the temple tips (earsocks). It's designed to increase grip when you sweat, preventing the glasses from slipping during activity. Customers report that it works as advertised—the frames stay secure even during physical work or outdoor activities without feeling tight or uncomfortable.
What face shapes work best with the Barrelhouse 0.5 rectangle frames?
The rectangular shape of the Barrelhouse 0.5 is particularly flattering on square and heart-shaped faces, as it provides balance and definition. The semi-rimless design and clean lines also work well for oval faces. The adjustable nosepads allow for customization to ensure proper fit and alignment regardless of face shape.
Can I get prescription lenses installed in the Oakley Barrelhouse 0.5 frames?
Absolutely. The Barrelhouse 0.5 is fully prescription-ready and compatible with single vision, progressive, and bifocal lenses. The semi-rimless design accommodates most prescription strengths, and customers have successfully used them with prescriptions ranging from mild to -5.50 and higher when paired with high-index lenses for reduced thickness.

Oakley Barrelhouse 0.5 vs. Oakley Airdrop: Which Frame Is Right for You?
If you're choosing between the Oakley Barrelhouse 0.5 3174 and the Oakley Airdrop 8046, you're comparing two very different approaches to prescription eyewear. Both are prescription-ready Oakley frames built to last, but they serve different style preferences.
The Barrelhouse 0.5 takes a refined, architectural approach with its semi-rimless design. The lightweight C-5 alloy construction, raised nose bridge, and clean lines create a professional look that works in business settings and casual environments alike. One customer who tried both models put it simply: after ordering the Airdrops, "The Barrelhouse was the remedy. These look good and fit very well." The semi-rimless design is noticeably lighter and less bulky on the face.
The Airdrop 8046, by contrast, is a full-rim frame with a sportier aesthetic. It offers maximum lens protection and a more casual, active look. If you prioritize durability for high-impact activities or prefer a bolder frame presence, the Airdrop delivers. However, multiple reviewers noted it looks "nerdier" and less refined than the Barrelhouse.
Our take: Choose the Barrelhouse 0.5 if you want a versatile, professional frame that disappears on your face while still delivering Oakley's signature durability. It's the better choice for office wear, progressive lenses, and anyone seeking a minimalist aesthetic. The Airdrop is better suited for those who prefer full-rim protection and a more casual, sporty look.
Barrelhouse 0.5 vs. Steel Plate 3222: Comparing Semi-Rimless Oakley Frames
Both the Barrelhouse 0.5 and the Oakley Steel Plate 3222 offer semi-rimless metal construction in similar price ranges, but the Barrelhouse 0.5 stands out for its distinctive architectural design. The raised nose bridge and temple lugs give it a more sculptural, modern appearance, while the Steel Plate takes a more traditional semi-rimless approach. Both use C-5 alloy and integrated spring hinges, so comfort and durability are comparable. Your choice comes down to whether you prefer the Barrelhouse's bolder design statement or the Steel Plate's understated simplicity.
