Ray-Ban RB3724D Sunglasses

Start with fit – the frame should sit comfortably on your nose and ears without pinching or sliding. The lens should cover your eyes fully without touching your lashes.

From there, think about how you'll wear them. If you drive or spend time near water, polarised lenses are worth considering. If you want one pair that works indoors and out, photochromic lenses are a practical option. If you need vision correction, all Ray-Ban frames available through Spectacle 1286 can be fitted with prescription lenses to your specification.

As a general guide:

Round faces tend to suit angular or rectangular frames, which add definition. Square faces are balanced by rounder or oval shapes that soften strong features. Oval faces have the most flexibility and suit most frame styles. Heart-shaped faces – wider at the forehead, narrower at the chin – work well with frames that are wider at the bottom, like aviators.

If you're unsure, the size guide on each product page gives the key frame measurements to help you find the right fit. And if you need any guidance before ordering, feel free to get in touch – we're happy to help you find the right frame.

Polarised sunglasses have a special filter built into the lens that blocks horizontal light – the kind that causes glare when it reflects off flat surfaces like water, roads, or car bonnets. The result is a clearer, more comfortable view in bright conditions, with noticeably reduced eye strain.

They're particularly useful for driving, watersports, and any time you spend extended periods in strong sunlight. For everyday wear, the difference is subtle but real – colours appear more vivid and contrast is sharper.

For most people, yes – but it depends how you use them. If you spend time outdoors in bright conditions, drive regularly, or are sensitive to glare, polarised lenses offer a meaningfully more comfortable experience than standard tinted lenses.

The one exception worth knowing: polarised lenses can make certain digital screens – sat-nav displays, ATMs, some dashboards – harder to read at certain angles. For most wearers this is a minor inconvenience, but it's worth bearing in mind.

Authentic Ray-Ban frames are easy to identify by their build quality. The frame should feel solid and well-finished, with no rough edges or loose hinges. Genuine frames come with a hard case, a cleaning cloth, and a certificate of authenticity.

All Ray-Ban frames sold through Spectacle 1286 are sourced directly from authorised suppliers, so you can be confident in their authenticity.
