Genuine eyewear. Clear sourcing. Confidence in every purchase.
Designer eyewear you can trust
Every pair of sunglasses and optical frames we sell is genuine designer eyewear. At Seaside Optics, our commitment to authenticity starts with where we source our stock and continues through the information we provide before you buy.
We are an official stockist of designer eyewear from Prada, Miu Miu, Burberry, Tiffany & Co., Swarovski and Ralph Lauren.
Where our eyewear comes from
All our eyewear is sourced from established industry suppliers, including EssilorLuxottica, Marcolin and Marchon. These are recognised names in the eyewear industry, working with eyewear and fashion brands to bring sunglasses and optical frames to retailers.
The fashion label on a frame and the company that manufactures or supplies it may have different names. Many designer brands work with specialist eyewear companies through licensing agreements. This is why an industry supplier’s name can sit behind a familiar designer collection.
EssilorLuxottica
An international eyewear and vision-care group with a portfolio of eyewear brands and expertise in frames, sunglasses and lenses.
About EssilorLuxottica ↗Marcolin

About Marchon ↗The supplier varies by brand and collection. These names describe our sourcing network; they do not mean that every brand we stock is supplied by all three companies.
Our authenticity promise
We sell genuine products, never replicas or imitations. Our supplier relationships underpin that promise, and our product descriptions give you the details you need to choose with confidence.
If you have a question about the origin of a particular pair, please contact us with the product link or model code. We can explain the sourcing information relevant to that item and help with questions about its markings, condition or accessories.
Clear product identification
Look for the brand, model reference and colour code in the listing, together with frame measurements where available. These details help you distinguish between similar designs and sizes.
Condition and accessories explained
Each listing states the condition and what is included. Cases, cloths, tags and original packaging vary between items. Please use the individual description to check exactly what you will receive.

Your questions, answered
Will my glasses come with a designer case?
Please check the individual listing. A case or other accessory is included only where stated. A missing case or tag does not, on its own, determine whether eyewear is genuine.
Can you help me understand the frame markings?
Yes. Send us the product link or model code and tell us what you would like to check. We can help you understand the model, colour and sizing information available for that pair.
What if I have an authenticity concern?
Contact us at opticalseaside@gmail.com with your order number, the model reference and details of your concern. Include clear photographs of any markings or features you would like us to review so we can investigate the specific item.
Where can I find delivery and returns information?
We offer tracked UK delivery and 14-day returns in line with our policies. Please read our shipping policy and returns and refunds policy for the full terms and return instructions.
