The brand is Unicoeye, and the lead offer is the Halloween Sale code at the top of this page that gives you four free cosplay lenses when you buy four. That Buy 4 Cosplay Lenses & Get 4 Free code is best if you want to double a cosplay or fashion lens order in one go and can add eight qualifying items to your cart. Use it on website orders and enter the promo at checkout before 1 November 2026.
Small orders (1 to 2 items) If you only need one or two clear contact lenses, the Buy 1 Clear Contact Lenses & Get 2nd 30% Off code applies when you add two clear pairs to your cart. That code takes 30% off the second pair, so it is the only relevant discount for a two pair clear lens purchase. The 20% off sitewide code also works on two items, so compare which gives the bigger discount on your exact pairs: the 30% off the second pair may beat 20% sitewide if the second pair is near the price of the first.
Medium orders (3 items) If you plan to buy three items, the Buy 2 Contact Lenses & Get 1 Free and the Buy 2 Clear Contact Lenses & Get 1 Free codes both apply when you add three qualifying items. Those codes let you pay for two and receive the third free. The Buy 3 Contact Lenses & Get 3 Free and Buy 3 Clear Contact Lenses & Get 3 Free codes require six items and so do not apply to three item carts. Also consider the 20% off sitewide code, but for three items the pay for two and get one free deals will usually save more than a straight 20% off across all three.
Medium large orders (4 to 5 items) For four items, the Buy 2 Cosplay Lenses & Get 2 Free code applies when you add four cosplay items, giving two free. If you add five items, none of the buy four promotions can be redeemed until you reach eight items, so you may be better off using the 20% off sitewide code across five items or hanging on until you can meet a higher free item threshold.
Large orders (6 items) If you add six items, the Buy 3 Cosplay Lenses & Get 3 Free, Buy 3 Contact Lenses & Get 3 Free, and Buy 3 Clear Contact Lenses & Get 3 Free codes take effect. These let you pay for three and get three free when the six items meet the qualifying product type. Compare that to 20% off sitewide; in quantity six freebies will usually be the better saver.
Very large orders (8 items or more) If you can add eight qualifying items, use the Buy 4 Cosplay Lenses & Get 4 Free code at the top of the page or the Buy 4 Eye Lenses & Get 4 Free code where applicable. Both require eight items and give four free, so pick the one that matches the product type in your cart. These will generally beat 20% off for large quantity buys of eligible lenses.
