• normal: regular clear lenses
• blue light filter: filters light rays from screens
• transition: inside the lenses are clear, in sunlight they become tinted
• sunglasses: we offer many colours and also polarised

If you scroll up a bit, you'll see the specifications. These are the sizes of hard to explain. You can compare these with your current glasses to get a good idea. You can also try them on digitally! Also, you can read our full article about determining frame size.

The production time is 7 business days (Saturdays, Sundays, and public holidays do not count). It does indeed take a while because we custom-make and grind the lenses for you. When hard to explain is finished, it will be shipped in a letterbox-sized package. Convenient, because you don't have to wait at home to accept the package. Here you can find more information about shipping.

Yes, that's possible! You can return hard to explain to us within 14 days of receipt. However, lenses are personalized products due to the various powers and lens options available. Lenses that incur an additional charge combined with a prescription will not be refunded upon return. In that case, only the price of the frame will be refunded. To be sure, please read our returns policy. Another tip: try on the glasses digitally first and make sure you like the frame color!
