TIP15-day delivery via Aliexpress Standard Shipping

For this product, Aliexpress Standard Shipping is available with guaranteed delivery within 15 days. It’s the most reliable delivery method and, in most cases, it’s handled by a courier company. The 15-day delivery is something we actually tested.

When you order from a Chinese warehouse, AliExpress adds a customs duty charge of approximately 3,70 € per order to your cart. When you receive the shipment, you won’t have to pay anything extra.

Are you shopping on AliExpress for the first time?

The process is via the AliExpress mobile app, where most people shop. There are two key things: don’t use Buy now and enter the coupon only in the order summary, in the field Promo code. After you click Pay now, you won’t be able to add it.

  1. Copy the code and click Use discountIn our article, copy the coupon and click the button GET DISCOUNT. The link will take you directly to the product in the AliExpress app.
  2. Use Add to cart instead of Buy nowOn the product card, scroll down and tap Add to cart. Don’t use the Buy now button—you’ll skip the cart, and later you won’t have anywhere to enter the coupon. Before that, double-check the variant: the color, the version, and whether it ships from an EU warehouse.
  3. Through the cart, go to CheckoutA pop-up will appear: Added to cart! — tap Check it out in it. If it disappeared, open the cart with the icon at the bottom right. In the cart, check the product and quantity, then click the red Checkout. Only the items marked with the red ring will be applied.
  4. Enter your address and card, then look for Promo codeIn the order summary, first fill in the delivery address and payment card at the top. Below them there’s a line Promo code — expand it with the arrow on the right.

    Riadok Saved s uplatneným kupónom a znížený Total v aplikácii AliExpress
    The applied coupon will appear in the Saved line and will reduce the Total.
Apply the discount already at the order summary. After you click Pay now, you can no longer add a coupon. If Apply shows an error, the code has either expired, doesn’t apply to your items, or the order doesn’t meet the minimum amount.
The Store Coupon also goes in the same field. — a coupon from the seller itself, which isn’t always available and changes from day to day. AliExpress coupons can’t be combined, so try both and go with the one that gives you more. Coins are added automatically.

Adaptive lens: perfect in the day and at night

The model is equipped with photochromic technology, which automatically adjusts the light transmission level based on the surrounding lighting. In low light, it lets through up to 84.04 % of the light, which is ideal for riding at sunset or in the forest. Under strong UV exposure, it darkens and transmits only 24.88 %, protecting your eyes from glare.

The offer also includes special colored photochromic lenses that shift the tint to violet-pink depending on the intensity of UV exposure. Besides protection, you also get a stylish and unique look. The color gradient looks elegant and interesting—just like today’s sporty design demands.

UV400 technology and professional testing

The glasses meet strict UV filtration standards and are equipped with UV400 protection. This effectively blocks all UVA and UVB rays (280 – 400 nm), protecting your eyes even during all-day wear. According to a certified test, all values are within the standard and the glasses passed Category 3 filtration—ideal for outdoor sports activities.

Test results show 0 % release in dangerous UVB and UVA zones, with minimal transmission in the visible light spectrum. That means your eyes are perfectly protected even on a sunny summer day in the mountains or by the sea.
