Description

The Stepper SI-81505 F010 is a lightweight premium rimless optical frame from Stepper’s German-engineered comfort eyewear collection, designed around the brand’s philosophy of ultra-light wearability, ergonomic balance, and minimalist everyday styling. This model is intended for users who prioritize long-term comfort, refined professional aesthetics, and pressure-free daily wear over heavy fashion-oriented eyewear designs.

The SI-81505 features a rimless rectangular silhouette with slim geometric contours and a lightweight drill-mounted construction that creates a clean floating-lens appearance. The rimless architecture minimizes both physical and visual bulk, giving the frame a modern and highly professional look suitable for office, executive, and daily business wear. The narrow rectangular lens geometry also provides a refined and understated masculine appearance.

The “F010” color code is associated with a matt bronze / gold-brown metallic finish, giving the frame a warm and elegant appearance compared to traditional silver or black rimless designs. The finish combines understated luxury with versatile professional styling, making it appropriate for both formal and smart-casual environments.

Build & Materials

The SI-81505 F010 is primarily constructed using ultra-light titanium, one of the core materials within Stepper’s comfort-focused engineering philosophy. Titanium construction provides:

Extremely lightweight all-day wear comfort
High structural durability with flexibility
Corrosion-resistant performance
Hypoallergenic properties suitable for sensitive skin
Reduced facial pressure during prolonged wear

The rimless drill-mounted structure further minimizes total frame weight. Several retailers list the frame weight around 5–10 grams depending on lens configuration, highlighting Stepper’s emphasis on near-weightless comfort engineering.

Design & Comfort Features

This model incorporates several ergonomic comfort-oriented details:

Rimless rectangular drill-mounted frame structure
Adjustable silicone nose pads for personalized fit
Slim lightweight titanium temples
Balanced frame weight distribution for prolonged comfort
Straight ergonomic temple design for secure positioning
Minimalist German comfort-engineered styling

The SI-81505 is especially suitable for office work, reading, and prolonged screen use due to its ultra-light titanium construction and low-pressure ergonomic fit.

Fit & Sizing

Available sizing specifications for the SI-81505 vary slightly depending on production version and regional distribution, but commonly listed dimensions include:

Lens width: 49–52 mm
Bridge width: 20–23 mm
Temple length: 145 mm
Approximate frame width: 128 mm

Its rectangular rimless geometry works especially well with lightweight progressive lens configurations and modern digital-use prescriptions. Retailers frequently recommend high-index or Trivex lenses for optimal cosmetic balance in rimless drill-mounted frames.
