How to Choose Luxury Sunglasses: 5 Things That Actually Matter

The $150–$300 price range for sunglasses contains both genuinely excellent optics and largely mediocre product sold on brand name alone. Here are five factors that separate the two.

1. Lens Material

Glass lenses deliver superior optical clarity and scratch resistance but are heavier and shatter on impact. Polycarbonate lenses are impact-resistant and light but scratch more easily. CR-39 plastic (used by Ray-Ban) sits between the two — lighter than glass, optically clearer than polycarbonate. For everyday wear, CR-39 is the practical optimum. For heavy outdoor and active use, polycarbonate is safer. Glass is the premium optical choice if weight and impact risk aren’t concerns.

2. Polarisation Quality

All polarised lenses reduce glare, but not equally. Basic polarised lenses filter horizontal light waves, which eliminates most road and water glare. Premium polarisation systems (like Maui Jim’s PolarizedPlus2) additionally enhance colour saturation and contrast. The difference is immediately visible in bright outdoor conditions. If you spend significant time outdoors near water or driving in sun, premium polarisation is worth the price. For urban everyday wear, standard polarisation or even non-polarised lenses are usually sufficient.

3. Frame Construction

Acetate frames are the quality standard for lifestyle sunglasses — more durable than injection-moulded plastic, better colour depth, and can be adjusted by a skilled optician. Metal frames (titanium, stainless steel) are lighter and more durable but offer less design flexibility. Italian acetate (used by Persol and high-end Ray-Ban) is the benchmark material. Check where the frame is manufactured — Italian and Japanese-made frames generally indicate higher quality control than mass-production facilities.

4. UV Protection

All reputable sunglasses at this price point should offer 100% UVA/UVB protection (UV400). This is not a differentiator at the $150+ price point — it’s a baseline requirement. If a pair at this price cannot confirm UV400 protection, don’t buy them. Lens darkness has no correlation with UV protection; a very dark lens without UV coating protects worse than a light lens with UV coating, because the dark tint causes pupils to dilate while the UV passes through.

5. Fit and Coverage

Sunglasses that don’t fit will be worn less, defeating the purpose. Frame width should match your face width — most brands offer measurements in millimetres on the inside of the temple arm (e.g., 52-18-145 = lens width, bridge width, temple length). Coverage matters too: small frames that leave significant gaps around the lens offer less sun protection than frames with better coverage. Try before buying when possible, or purchase from retailers with good return policies.
