SmartBuyGlasses is showing the 50% off a second SmartBuy Collection frame voucher at the top of this page, and it is best if you plan to buy two SmartBuy Collection frames. The voucher halves the price of the second eligible SmartBuy Collection frame when you add two eligible frames to your cart and apply the voucher at checkout.
If you are buying two SmartBuy Collection frames: the 50% off voucher is usually the biggest saver. For example, on a €120 first frame and an €80 second frame, the voucher reduces the second from €80 to €40, so your total falls from €200 to €160, a saving of €40. Use the 50% off voucher at checkout for that pair.
If most of your spend is lenses or upgrades with a Value Collection frame: use the 15% off Value Collection lenses, upgrades and coatings code. For instance, on a €120 Value Collection frame plus €80 in lenses and upgrades, the 15% code applies only to the €80 lens component, cutting it to €68, so the order drops from €200 to €188, a saving of €12.
If you are buying lenses, upgrades or coatings but not a Value Collection frame: the 10% off lenses, upgrades and coatings voucher is the general choice. On €200 of lenses and coatings, 10% off reduces the cost to €180, saving €20, which will beat a 5% basket code in most such lens heavy carts.
If you are buying Value Collection frames alone: the 10% off all Value Collection frames voucher applies. On a €100 Value Collection frame, 10% off brings the price to €90, saving €10.
If you have a mixed basket of different items or brands where no specific voucher applies: the 5% off your entire basket voucher can be the simplest route. On a €200 mixed basket that is not excluded, 5% off saves €10.
If you are buying designer eyewear and can reach the thresholds: choose the fixed amount voucher that your basket qualifies for. The €10 off voucher requires a minimum spend of €200 and excludes Ray‑Ban; the €25 off voucher requires €400 minimum and excludes Ray‑Ban. For example, a €450 qualifying designer order becomes €425 with the €25 voucher, saving €25.
If you are ordering contact lenses: use the 5% off contact lenses voucher on orders over €65. On a €120 contact lens order, 5% off reduces the price to €114, saving €6.
If a sale item or the €8 prescription deal applies to your chosen product: the marked sale price or the €8 prescription offer will often be cheaper than any small percentage voucher on a single item. The Back to School sale advertises up to 75% off selected designer styles and may undercut voucher savings on that item.
Our records for the 12 months to November 2026 show 20 offers listed for the brand (17 codes and 3 sales or deals). The biggest percentage code we recorded in that window was 50% off and the typical percent code was 10%. Our team ran 19 checkout tests across 15 offers in the 12 months to November 2026 and kept screenshots as proof.
When choosing between the applicable offers for your basket, calculate the final price with each voucher that actually applies and take whichever leaves the lowest total. Only one voucher can be entered at checkout, so use the single one that reduces your final payment the most, or rely on the sale marked price if that is lower.
