DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Oakley Socket 5.0 3217 prescription eyeglasses bring Oakley's sports DNA into a refined rectangular frame you can wear anywhere. Built from lightweight C-5 alloy—a five-metal compound engineered for strength and flexibility—these full-rim frames deliver the durability Oakley is known for without the weight.

Industrial Design Meets Everyday Comfort

The Socket 5.0 pays tribute to Oakley's industrial design roots. Look closely at the bottom of the lens orbitals and you'll see swept angles inspired by the chamfers on a socket wrench—subtle detailing that adds dimension to an otherwise clean silhouette. The rectangular shape works well on round or oval faces, and the full-rim construction makes these frames compatible with progressive and bifocal lenses.

Oakley's Three-Point Fit system holds the frame at exactly three contact points: the bridge and both temples. This reduces pressure and keeps your lenses in precise optical alignment throughout the day. Integrated spring hinges flex to accommodate different head shapes, while Unobtainium earsocks and adjustable silicone nosepads ensure a secure grip that actually improves when you sweat—a feature borrowed from Oakley's performance eyewear.

Prescription-Ready in Three Sizes

These frames are prescription-ready and available in 53mm, 55mm, and 57mm eye sizes to fit a range of face widths. The metal construction allows for easy adjustments by an optician. Multiple color options—from classic satin black and pewter to brushed chrome and navy—let you match your style.

Each pair ships with an Oakley protective case. If you're looking for a no-nonsense prescription frame that can handle daily wear without sacrificing Oakley's engineering standards, the Socket 5.0 delivers.

Frequently Asked Questions

Are Oakley Socket 5.0 eyeglasses prescription-ready?

Yes, the Oakley Socket 5.0 3217 frames are fully prescription-ready. The full-rim design accommodates single vision, progressive, and bifocal lenses. These frames work with a wide range of prescriptions and can be fitted with various lens materials including polycarbonate and high-index options.

What is C-5 alloy and why does Oakley use it?

C-5 alloy is Oakley's proprietary metal frame material created by fusing five metallic compounds together. It's lighter than steel, extremely durable, and flexible enough to withstand daily wear without breaking. The alloy provides a premium feel while keeping the frames lightweight for all-day comfort.

What sizes are available for the Socket 5.0?

The Oakley Socket 5.0 comes in three eye sizes: 53mm (smallest), 55mm (medium), and 57mm (largest). All sizes feature a 17mm bridge width. The temple length is either 136mm or 138mm depending on the variant. The 53mm size works well for narrower faces, while the 55mm and 57mm fit medium to wider face shapes.

What is Oakley's Three-Point Fit system?

Three-Point Fit is Oakley's patented fitting technology where the frame only contacts your head at three points: the bridge of your nose and the back of each temple. This eliminates uneven pressure points and holds the lenses in precise optical alignment, ensuring your prescription works exactly as intended throughout the day.

What are Unobtainium earsocks and how do they work?

Unobtainium is Oakley's proprietary rubber material used on the temple tips (earsocks) and nosepads. Unlike regular rubber, Unobtainium actually gets tackier and grippier when it comes into contact with moisture or sweat. This means the frames stay securely in place during physical activity or in warm conditions.

How does the Socket 5.0 compare to the Socket 5.5?

The Socket 5.0 features a full-rim frame design, while the Socket 5.5 has a semi-rim (half-rim) construction. Both share the same swept lens angles, C-5 alloy material, spring hinges, and Three-Point Fit. The 5.0 is slightly heavier but offers more durability and better support for stronger prescriptions and progressive lenses.

Read the full comparison

Socket 5.0 vs Socket 5.5: Full-Rim or Semi-Rim?

The most common comparison is between the Socket 5.0 and its sibling, the Socket 5.5. Both frames share the same industrial design language—those distinctive swept angles at the bottom of the lenses inspired by socket wrench chamfers—and both use C-5 alloy construction with Unobtainium grips and Three-Point Fit.

The difference comes down to rim style. The Socket 5.0 is a full-rim frame, meaning metal surrounds the entire lens. This makes it more durable and better suited for progressive lenses or stronger prescriptions. The Socket 5.5 is semi-rim (the bottom of the lens is exposed), which creates a lighter, more minimalist look but sacrifices some structural support. If you prioritize durability and versatility, the 5.0 is the better choice. If you want a lighter, more contemporary aesthetic and have a moderate prescription, consider the 5.5.

Socket 5.0 vs Plank 2.0: Metal or Plastic?

The Oakley Plank 2.0 is another rectangular frame that customers frequently compare to the Socket 5.0. The key difference is material: the Plank 2.0 uses Oakley's O Matter plastic, while the Socket 5.0 is metal C-5 alloy.

O Matter is incredibly lightweight and impact-resistant, making the Plank 2.0 a great choice for active lifestyles. It's also more affordable ($95.33–$187 vs $196–$227 for the Socket 5.0). However, plastic frames can't be adjusted as precisely as metal, and they lack the refined, professional aesthetic that metal provides. If you work in a business environment or prefer a more polished look, the Socket 5.0's metal construction is worth the premium. If you prioritize lightweight comfort and value, the Plank 2.0 delivers.

Why Choose the Socket 5.0?

The Socket 5.0 occupies a sweet spot: it's more durable and adjustable than the Socket 5.5, more refined than the Plank 2.0, and more affordable than Oakley's premium metal frames like the Gauge series. The full-rim metal construction, spring hinges, and Three-Point Fit make it a reliable everyday frame that can handle any prescription. If you want Oakley's engineering in a clean, professional package, the Socket 5.0 is the frame to choose.
