15% off eligible prescription glasses
Best for shoppers buying eligible prescription glasses who want to test the main code before comparing sale categories.
Top-bar codeUse PDAY15 first if you are buying eligible prescription glasses at Fytoo. Then compare the Flash Sale, where select frames are shown as low as US$1.00, and the BOGO 50% frames offer before checkout.

Top-bar code
PDAY15 appeared as applied in the Fytoo checkout screenshots and showed a 15% off eligible prescription glasses discount line. Check your final order total before paying because frame, lens and cart setup can change the final number.
Best for shoppers who want the deepest visible markdowns and are willing to pick from limited sale frames instead of the full catalog.
Best percentage dealBest when your cart has one glasses item and an additional frame. Check the cart discount line before paying because the BOGO saving depends on cart setup.
Best multi-frame dealThe clean move is simple: copy PDAY15 if your cart includes prescription glasses, then compare whether the Flash Sale or BOGO 50% path gives you a better final cart. The best-looking percentage is not always the best checkout total, because lenses, quantity and shipping threshold matter.

PDAY15 is worth testing first because it is clear, short, and tied to the main buyer intent: eligible prescription glasses.
The Flash Sale is the strongest category-level discount shown here. It is best when you want a low frame price and do not mind choosing from limited sale styles.
Use PDAY15 first. It is the direct code path for eligible prescription glasses and should be checked before you pay.
Start with the Flash Sale. It is the best path when you care more about the lowest frame price than picking from every Fytoo style.
Use the BOGO 50% frames path when your cart has one glasses item plus another frame. It can beat a single-item discount if the checkout shows the BOGO line.
Use these spotlights to choose the right sale path without chasing a single SKU that may change price or availability later.
Use this when you want the lowest visible price first. The trade-off is selection: Flash Sale styles can be limited, so do not treat it as a full-catalog discount.

This is the better path when your cart includes one glasses item plus another frame. It does not have to be two full prescription pairs, but the checkout must show the BOGO 50% discount line before you treat it as verified.

Start with the cart type first, then the discount. A 96% category sale can look stronger than a 15% code, but checkout math still decides the better deal.
Try it on prescription glasses and confirm the discount line appears before payment.
Pick Flash Sale when you are flexible on frame style and want the deepest visible markdown.
The BOGO 50% path makes more sense when you already want one glasses item plus another frame, not when you are forcing an extra item into cart for sport.
Free shipping over US$69 can change the real value of a small-cart deal.
Make sure PDAY15 appears as an applied discount before payment. A copied code is not proof. The final discount line is proof.
Check the live price again before paying. Flash Sale pricing can change, and your checkout should match the current page.
Confirm frame color, prescription type, lens add-ons and coatings. Those choices can move the final cart total.
Use the BOGO path only when the cart clearly shows the BOGO 50% discount line.
Free standard shipping is listed for orders above US$69, so small carts may still need a shipping check.
Check the return and warranty policy before paying, especially if you are ordering prescription lenses or multiple frames.
Fytoo free standard shipping applies on orders above US$69 in eligible countries. Use this as a checkout-cost check, not a product discount.
Check Fytoo shippingFytoo return and exchange terms are useful for shoppers checking fit, prescription setup and final order confidence before checkout.
Read return policyFytoo warranty notes cover frames, sunglasses and prescription lenses according to Fytoo’s policy page.
Read warranty notesCheck these details before you buy so the visible discount still makes sense after code eligibility, lens choices, shipping and return terms.
Skip the code claim if PDAY15 does not appear before payment. The checkout discount line is the only line that matters.
Frame price and final prescription-glasses total are not always the same thing. Lens type and coatings can change the cart.
Do not assume PDAY15, Flash Sale and BOGO 50% all stack automatically. Checkout is the final source of truth.
Check color, RX type, lens choice and quantity before paying. Eyeglass deals are useless if the variant is wrong.
Start with PDAY15 if you are buying eligible prescription glasses. Choose Flash Sale if the lowest single-frame price matters most. Choose BOGO 50% if you are buying one glasses item plus another frame. Then check shipping over US$69, return terms and warranty notes before checkout.
