Sunglasses are functional eyewear plus accessory. Cheap pairs (£10-30) scratch quickly, offer questionable UV protection, and rarely flatter. Quality pairs (£80-300) last 5-10 years, protect eyes properly, and become signature pieces of wardrobes.
What 'quality' means
100% UV400 protection (look for certification). Polarised lenses for outdoor activity (reduce glare). Frame material (acetate or metal preferred over plastic). Fit your face shape (this matters more than brand).
UK options
Cubitts (independent British), Bailey Nelson (mid-range), Ray-Ban or Oliver Peoples (heritage). High-street optical shops often have own-brand quality at £80-150.
Buy one pair you genuinely love. Care for them. Replace every 5-10 years. The cost-per-wear maths is excellent.
