PC Frame Polarised Sunglasses with UV400 Protection for Driving and Outdoor Activities
These polycarbonate frame sunglasses feature 55mm polarised lenses that reduce glare by filtering horizontal light waves, making them particularly effective for daytime driving and outdoor activities like mountaineering. The universal frame design accommodates face widths between 135-150mm, while the 2.5mm thick lenses provide impact resistance suitable for active use. With five colour variations offering different light filtration properties, these glasses combine practical eye protection with versatile styling options for various lighting conditions and personal preferences.
Features and Construction Quality
This section details the specific construction elements that contribute to the sunglasses' performance and durability, including material properties, frame technology, and protective features that make them suitable for both casual wear and outdoor activities.
Frame Design and Materials
The injection-moulded polycarbonate frame maintains consistent shape through its single-piece construction, eliminating weak points at the bridge and temples. The 135-150mm width range accommodates most adult face sizes without pressure points, while the integrated nose pads prevent slippage during movement. Frame thickness varies from 3mm at the temples to 5mm at the stress points around the hinges, providing structural integrity without excessive weight.
Lens Technology and Protection
The 55mm polycarbonate lenses provide UV400 protection, blocking 99.9% of UVA and UVB rays with consistent coverage across the entire lens surface. Polarisation efficiency measures at 99% for horizontal light wave filtration, reducing reflected glare from surfaces like water, snow, and roads. The 2.5mm thickness offers impact resistance equivalent to 3mm of standard optical glass while maintaining optical clarity with minimal distortion at the edges.
Durability and Construction
Stainless steel hinge pins measuring 1.2mm diameter withstand approximately 10,000 opening cycles without failure, while the injection-moulded frame maintains integrity at temperatures from -10°C to 60°C. The rubberised temple tips composed of thermoplastic elastomer provide 35mm of textured surface area with coefficient of friction measuring 0.8, ensuring secure positioning behind the ears during physical activity.
Practical Applications and Usage Scenarios
These sunglasses serve multiple purposes across different environments and activities, from daily commuting to specialised outdoor pursuits where eye protection and visual clarity are essential for safety and comfort.
Driving and Road Use
During daytime driving, the polarised lenses reduce dashboard reflection and windscreen glare by approximately 70%, improving contrast perception for hazard detection. The universal frame design maintains comfort during extended periods behind the wheel, while the 145mm temple length prevents pressure points when resting against headrests. The five colour options provide specific benefits - grey lenses maintain natural colour perception, while blue lenses enhance contrast in overcast conditions.
Outdoor and Recreational Activities
For mountaineering and hiking, the UV400 protection blocks intense high-altitude UV exposure, while the impact-resistant polycarbonate construction withstands minor impacts from branches or falling debris. The secure temple grip maintains position during vigorous movement, and the lightweight 28-gram frame reduces fatigue during extended wear. The polarised lenses effectively reduce glare from snow, water, and rock surfaces common in outdoor environments.
Everyday Urban Use
In daily urban environments, the sunglasses provide consistent protection from reflected glare off buildings and pavements, while the fashion-forward styles complement casual and business-casual attire. The compact storage case facilitates carrying in bags or pockets, and the durable construction withstands the rigours of daily use including frequent storage and retrieval. The universal fit accommodates different facial structures encountered in diverse urban populations.
Performance Benefits and Value Considerations
The combination of protective features, durable construction, and versatile design provides measurable benefits across various usage scenarios, offering reliable eye protection and visual comfort through consistent performance.
Long-Term Value and Durability
With an expected service life of 2-3 years under normal usage conditions, the sunglasses provide cost-effective eye protection compared to frequent replacement of cheaper alternatives. The polycarbonate material maintains optical properties without yellowing or degradation from UV exposure, while the stainless steel hinges prevent the common failure point of cheaper spring-loaded mechanisms. The scratch-resistant lenses maintain clarity through regular cleaning and storage.
Comfort and Wearability
The weight distribution across the 135-150mm frame width prevents pressure points on the nose and temples, while the rubberised temple tips eliminate slipping during physical activity. The universal fit accommodates different facial structures without requiring adjustment, and the consistent 55mm lens diameter provides adequate peripheral vision coverage without visual obstruction. The integrated nose pads maintain position without requiring separate components that can be lost.
Purchase Considerations
These sunglasses represent a practical investment for individuals requiring reliable eye protection across multiple activities, with the polarised lenses providing measurable glare reduction and the durable construction ensuring consistent performance. The five colour options allow selection based on specific lighting conditions and personal style preferences, while the universal fit eliminates the need for custom fitting or adjustments. The comprehensive UV protection meets British standards for eyewear safety across various outdoor environments.
