Retro Square Frame Sunglasses for Men with Full UV400 Protection

These retro square frame sunglasses for men offer UV400 protection that blocks all harmful rays up to 400nm, essential for UK summers where UV exposure rises despite cloudy skies. Crafted with PC lenses and metal frames, they weigh around 25g, light enough for all-day wear without fatigue. Available in black or gold frames with grey, tea, or blue tints, the design fits most face shapes from 13 to 15cm wide. Square lenses measure 55mm across, providing broad coverage that reduces squinting by minimising peripheral glare. The metal alloy construction ensures the frame returns to shape after minor bends, unlike cheaper plastics that deform easily. Double gradient options in gold frames layer tints for better light control in variable weather, enhancing visibility during drives or hikes.

Features and Construction Quality

This section covers the key elements of UV400 retro square sunglasses, including lens tints and frame durability. Expect details on how materials perform in everyday British conditions like rain or wind.

Square Frame Design

The square frame design spans 135mm in total width, with 55mm lenses that sit flush on bridges of 18mm. This geometry suits oval and round faces common in the UK, preventing light leaks at the sides. Metal arms extend 140mm, hooking securely over ears without slipping during 30km/h winds. Black frames use a matte finish to cut reflections, while gold adds a subtle sheen from plated alloy. The 45mm frame height keeps temples elevated, avoiding cheek contact that smears lenses after 20 minutes of wear. Riveted hinges allow 90-degree opening, tested to 10,000 cycles without loosening.

Lens Technology Details

PC lenses deliver UV400 blockage across the full spectrum, absorbing 99.9% of rays at wavelengths from 280-400nm. Grey sheets transmit 15% light for balanced vision in partial sun, ideal for urban commutes. Double tea tints in gold frames reduce infrared by 40%, keeping eyes cooler in 25°C heat. Grey blue variants shift hues slightly for better colour accuracy in green landscapes. Lens curvature of 6 base prevents distortion up to 20 degrees off-axis, ensuring safe peripheral checks while cycling. Impact tests show they withstand drops from 1.2m onto concrete without cracking.

Build and Durability Aspects

Metal frames employ nickel-free alloy to avoid skin reactions, lasting through 200 hours of sweat exposure. PC material in lenses resists temperatures from -10°C to 50°C, suitable for UK winters and heatwaves. Nose pads adjust 2mm for custom fit, distributing 25g weight evenly to prevent marks after 8 hours. Coating on gold frames resists tarnish for 12 months under normal use, outperforming uncoated metals that fade in 3 months. Hinge screws use stainless steel, tightening without tools after minor wear. Overall, the build handles daily knocks equivalent to 5 years of moderate activity.

Practical Applications

Explore how these retro square frame sunglasses apply to various settings, from professional tasks to casual outings. They adapt to driving, sports, and social events with reliable UV400 coverage.

Professional Outdoor Use

For builders or delivery drivers facing 8-hour shifts in variable light, the UV400 lenses shield against cumulative exposure that builds to 2 hours of direct sun equivalent daily. Square frames stay put during ladder climbs, with 140mm temples gripping without adjustment every 30 minutes. Gold frame double grey suits site inspections, cutting glare from screens in vans by 70%. Black frames work for surveyors in fields, where grey powder tints enhance contrast on maps under overcast skies. The lightweight metal avoids the 50g bulk of safety glasses, allowing longer focus without breaks. In construction zones, they comply with basic eye protection needs by blocking debris impacts up to 1.5kg.

Everyday Consumer Scenarios

On a Bank Holiday picnic in the park, the tea-tinted lenses dim bright grass reflections, letting you read a newspaper without shielding your eyes every 10 minutes. During a 5km walk along the Thames, grey blue sheets maintain colour in watery glare, spotting details like birds at 50m. Black frame grey fits commutes on the Tube's escalators, blocking fluorescent flicker that strains after 20 stops. For weekend gardening, the square shape covers the full field of view while pruning, reducing head tilts by 15 degrees. Gold frames add a nod to 70s style for pub lunches, without the shine overwhelming casual looks.

Versatile Style Options

Switch the gold frame double tea for evening drives, where the tint layers provide night-time contrast without darkening too much. Pair black frame grey with a Barbour jacket for countryside rambles, matching the muted tones of British moors. Use grey powder on overcast days for subtle enhancement, or blue for coastal paths where sea hues pop. The metal finish transitions from office blazers to football matches, holding up in light rain without rust spots. Combine with hats for fishing trips, extending shade by 10cm over the brow for added UV block.

Key Benefits Overview

Long-Term Value

Investing in these metal frame sunglasses saves £100 over 3 years compared to plastic pairs that crack after 50 drops, as metal withstands 200 impacts.
