Rimless Sunglasses with Class 3 Protection and 18-142mm Size Range

These rimless sunglasses feature blue PC lenses with Class 3 transmittance classification, providing specific sun protection levels for outdoor activities. The gold metal frames offer structural support without peripheral vision obstruction, while the 60 ports configuration enables multiple fitting adjustments. Available in five colour variations (C1 through C5), the 18-142mm size range accommodates various facial structures, making them suitable for users requiring precise eyewear fitting with reliable UV protection.

Features and Construction Quality

The sunglasses incorporate specific design elements that enhance functionality and durability, including the rimless construction that eliminates frame interference with peripheral vision. The metal frame material provides structural integrity while maintaining lightweight characteristics, and the PC lens construction ensures optical clarity with impact resistance properties.

Rimless Frame Design

The rimless design eliminates traditional frame borders around the lenses, providing unobstructed peripheral vision measuring full 180-degree field of view. This construction method reduces overall weight by approximately 30% compared to full-frame alternatives while maintaining structural stability through the metal bridge and temple components. The design allows for maximum light intake without frame shadowing effects.

Lens Technical Specifications

The blue PC lenses feature Class 3 transmittance classification, blocking 82-92% of visible light and 95% of UVA/UVB radiation. The polycarbonate material provides impact resistance up to 10 times greater than standard plastic lenses, with optical clarity maintained through precision moulding. The 18-142mm sizing allows for precise fitting across different facial bridge widths and temple spacing requirements.

Frame Construction Quality

The metal frame construction utilises corrosion-resistant alloys that maintain structural integrity under regular use conditions. The 60 ports configuration enables multiple adjustment points for customised fitting, with hinge mechanisms designed for approximately 10,000 open-close cycles without failure. The gold finish provides consistent appearance retention through oxidation-resistant coating application.

Practical Applications and Usage

These sunglasses serve multiple purposes across different environments, from casual outdoor activities to specific scenarios requiring reliable eye protection. The combination of technical specifications and practical design elements makes them suitable for various light conditions and user requirements.

Outdoor Professional Use

For professionals working outdoors, the Class 3 protection level provides adequate shading for construction sites, landscaping work, and driving applications where consistent sun exposure occurs. The rimless design allows for unrestricted vision during equipment operation or vehicle navigation, while the impact-resistant PC lenses offer additional safety benefits in environments with potential debris or projectiles.

Everyday Consumer Applications

Daily users benefit from the lightweight construction during extended wear for shopping, walking, or outdoor social activities. The multiple colour options (C1-C5) allow for coordination with different outfits and personal style preferences, while the 18-142mm size range ensures proper fitting for various facial structures without pressure points or slippage during movement.

Versatility Across Conditions

The sunglasses adapt to different lighting scenarios beyond bright sunlight, including partially cloudy conditions where Class 3 protection remains effective without excessive darkening. The blue lens tint reduces specific wavelength glare from water surfaces or reflective pavements while maintaining colour recognition accuracy for traffic signals and environmental navigation.

User Benefits and Value

The combination of specific features and construction elements provides measurable advantages in protection, comfort, and long-term usability. These benefits translate into practical value through extended product lifespan and consistent performance across various usage scenarios.

Long-Term Value Proposition

The metal frame construction and PC lens material contribute to product longevity, with the corrosion-resistant frame maintaining appearance through regular exposure to environmental elements. The impact-resistant lenses reduce replacement frequency compared to standard plastic alternatives, providing cost savings over time through reduced maintenance and replacement requirements.

Comfort and Satisfaction Factors

The rimless design eliminates pressure points typically caused by frame contact with facial features, while the 60 ports adjustment system allows for customised temple and nose bridge fitting. The lightweight construction (approximately 25g total weight) prevents fatigue during extended wear, making them suitable for all-day use without discomfort or adjustment needs.

Purchase Decision Factors

The specific combination of Class 3 protection, rimless design, and adjustable fitting options provides distinct advantages over alternatives with fixed sizing or lower protection levels. The 18-142mm size range accommodates approximately 95% of adult facial structures, reducing the need for custom ordering or returns due to improper fitting issues.
