How the Best Price Guarantee works at SmartBuyGlasses and when to use a voucher code
SmartBuyGlasses is one of the UK's largest online retailers for designer prescription glasses and sunglasses, offering frames from over 180 brands including Ray-Ban, Oakley, Tom Ford, Prada, Gucci and Versace. Because the company works directly with global distributors rather than going through middlemen, it consistently prices its eyewear below what you would pay at a high-street optician — often by 40% to 70%. The Best Price Guarantee goes a step further: if you find a product marked with the "Best Price Guarantee" badge available for less on another authorised retailer's site, SmartBuyGlasses will match that price, giving you confidence that you are not overpaying.
Voucher codes can be stacked on top of these already-reduced prices. The most popular ongoing code is SECONDPAIR, which gives you 50% off a second pair of glasses when you buy one at full price. This is particularly useful if you need both everyday glasses and prescription sunglasses, or if you want a backup pair. During seasonal promotions such as Black Friday, summer sales and Boxing Day, SmartBuyGlasses typically releases additional codes for 15% to 20% off single orders, making it one of the best times to stock up on eyewear.
SmartBuyGlasses runs a permanent outlet section where discontinued and older-season frames are discounted by up to 80%. If you buy one full-price pair and use the SECONDPAIR code on an outlet frame, your total out-of-pocket cost for two pairs of designer glasses can drop below £60. The outlet section is especially good for Ray-Ban Wayfarers and Oakley Flak frames, which appear there regularly at clearance prices.
Which voucher codes save the most on prescription glasses at SmartBuyGlasses
The type of voucher code you should look for depends on what you are buying. Here is a breakdown of the most common codes and when each one gives the biggest saving:
| Voucher code | Discount | Best for |
|---|---|---|
| SECONDPAIR | Buy 1 Get 1 50% off | Buying two pairs (glasses + sunglasses, or two prescriptions) |
| 20% off lenses | 20% discount on lens upgrades | Adding thin lenses, blue-light filtering or progressive lenses |
| Student Beans | 10% off entire order | Single-pair purchases for students with a valid .ac.uk email |
| £10 off £60+ | £10 off orders over £60 | Mid-range prescription glasses around £70–£120 |
| Arise Collective 20% off | 20% off Arise Collective range | SmartBuyGlasses' own-brand frames and lenses |
If you only need one pair, the 10% student discount through Student Beans is usually your best bet. For anyone buying two pairs, SECONDPAIR will almost always save you more. And if you are choosing premium lens options such as thin-index lenses or anti-reflective coatings, the 20% off lenses code will reduce what is typically the most expensive part of the order.
Why buying prescription glasses online from SmartBuyGlasses is safer than you think
A common concern about buying glasses online is whether they will fit correctly and whether the prescription will be accurate. SmartBuyGlasses addresses both points with a combination of tools and policies that make the process surprisingly low-risk.
First, the Virtual Try-On feature uses your device's camera to overlay frames on your face in real time. You can see exactly how a pair of Ray-Ban Clubmasters or Tom Ford glasses will look from every angle before committing. The tool has been refined over several generations and now works smoothly on both desktop and mobile browsers.
Second, the 100-day return and exchange policy is one of the most generous in the online eyewear industry. Most UK opticians offer 14 or 30 days; SmartBuyGlasses gives you over three months. If the glasses do not fit, the prescription feels wrong, or you simply change your mind, you can return them for a full refund or exchange. This policy also applies to prescription sunglasses.
Third, every frame comes with a 24-month warranty against manufacturing defects, and SmartBuyGlasses guarantees 100% authenticity on all designer brands. If you receive a product you suspect is not genuine, they will investigate and replace it free of charge.
You will need your current prescription details — sphere (SPH), cylinder (CYL) and pupillary distance (PD) — to order prescription lenses online. If you do not have a recent prescription, book an eye test first. Most UK high-street opticians are legally required to provide you with a copy of your prescription after a test, even if you do not buy glasses from them. Ordering with an outdated prescription can result in headaches and poor vision.
How to apply a SmartBuyGlasses voucher code at checkout
- Browse the SmartBuyGlasses UK site and select your frames — use the Virtual Try-On to check how they look on your face.
- Choose your lens type (single vision, progressive, or non-prescription) and add any lens upgrades such as blue-light filtering or thin-index lenses.
- Enter your prescription details. You can upload a photo of your prescription or type the values in manually.
- Go to your basket and look for the "Apply voucher code" field on the right-hand side of the checkout page.
- Paste your voucher code (for example, SECONDPAIR) and click "Apply". The discount will be reflected immediately in the order total.
- Complete your payment. SmartBuyGlasses accepts all major credit and debit cards, PayPal and Klarna for interest-free instalments on orders over £150.
Seasonal sale calendar: when SmartBuyGlasses drops its biggest discounts
Like most UK retailers, SmartBuyGlasses runs its biggest promotions around key shopping events. Knowing when these happen helps you time your purchase for maximum savings, especially if you can combine a seasonal code with the permanent SECONDPAIR offer.
| Sale event | Typical period | Expected discount |
|---|---|---|
| Boxing Day / January Sale | 26 Dec – 31 Jan | Up to 70% off + extra 20% code |
| Spring Sale | March – April | 15–20% off frames, outlet up to 80% |
| Summer Sale | June – August | Up to 60% off sunglasses, B1G1 50% |
| Back to School | August – September | 10% student discount + extra codes |
| Black Friday / Cyber Monday | Late November | Up to 70% off + rare 25% sitewide code |
The Boxing Day sale is consistently the best time to buy, with extra percentage-off codes that are rarely available during the rest of the year. Black Friday is the second-best window, particularly for prescription sunglasses heading into the southern hemisphere summer or for anyone buying a year's supply of reading glasses. During quieter months, the permanent SECONDPAIR code and outlet discounts are usually the best available offers.
Does the SmartBuyGlasses outlet actually beat high-street optician prices?
Yes — and by a significant margin in most cases. The SmartBuyGlasses outlet, called the Value Collection, stocks discontinued, end-of-line and older-season frames at prices that start from around £19 with standard lenses included. A comparable pair from Specsavers or Vision Express would typically cost between £79 and £149 for the frame alone. Even when you factor in lens upgrades (thin index, anti-reflective, blue-light), the total at SmartBuyGlasses is almost always lower.
The key advantage over buying from a high-street optician is that SmartBuyGlasses' outlet prices already include basic single-vision lenses. At many opticians, the advertised frame price does not include lenses, which can add £50 to £150 on top. At SmartBuyGlasses, lenses start from free (standard single vision) and only cost more if you choose premium options.
For budget-conscious shoppers, the Arise Collective range is SmartBuyGlasses' own-brand line. These frames are priced from around £25–£45 and regularly appear in the outlet with an additional 20% off code. The build quality is solid for the price — acetate frames with spring hinges — making them a practical choice for everyday wear.
Can I use a voucher code on outlet items at SmartBuyGlasses?
It depends on the specific code. The SECONDPAIR code works on both full-price and outlet frames, which makes it one of the most versatile codes available. Percentage-off codes (such as 20% off lenses) may not apply to already-discounted outlet items, so always check the terms on the voucher code page. If in doubt, try applying the code at checkout — the SmartBuyGlasses website will tell you immediately whether it is valid for your order.
Does SmartBuyGlasses accept NHS optical vouchers in the UK?
No, SmartBuyGlasses does not currently accept NHS optical vouchers. However, the prices on the site are often low enough that even without the voucher contribution, the total cost can be cheaper than using an NHS voucher at a high-street optician — particularly for designer frames. If you qualify for an NHS voucher (worth approximately £39.10 for single-vision lenses in 2026), compare the total out-of-pocket cost at both options before deciding.
How long does delivery take for prescription glasses?
Prescription glasses typically take 7 to 14 business days to arrive, as lenses need to be cut and fitted to your chosen frames. Non-prescription (plano) sunglasses and glasses ship faster, usually within 2 to 5 business days. All UK orders qualify for free delivery, with express shipping options available at an additional cost. SmartBuyGlasses provides order tracking so you can follow your glasses from the lab to your door.
What is the SmartBuyGlasses return policy?
SmartBuyGlasses offers a 100-day return and exchange window from the date of delivery. You can return glasses for any reason — wrong fit, prescription issues, or simply changing your mind — and receive a full refund or exchange. The glasses must be in their original condition with all accessories and packaging. To start a return, contact customer service through the website or reply to your order confirmation email.
