What if I need to change my order?

We process orders quickly, but we’ll do our best to accommodate any changes to your order. The best way to change or cancel an order is to write to info@sireneeyewear.com.


What’s the status of my order?

We will send to you e-mails with your orders status.

To check on the status of an order you can also sign into your account on www.sireneeyewear.com. Your info’s all there.




How do I submit my prescription?

Once you’re ready to checkout, you can upload an image (picture or scan) of your prescription to your order. If you’ve already placed an order, email the image of your prescription to info@sireneeyewear.com.


Do you fill all kind of prescriptions?

We commit to process prescriptions only for corrective lenses falling into Essilor standard range, that is, from -6 D to +6 D and with cylinder power up to and including 2.00.


Can you refuse to process my prescription?

Sirène reserves the right to refuse to process any prescription, when prescription contains incomplete data, is illegible or when Sirène internal aesthetic or safety norms may not be met.


Sirène reserves the right to refuse to process any prescription outside Essilor standard range. In such event our customer service will contact you to inform that the prescription cannot be processed and to establish further steps in processing the order.


Some powers of corrective lenses are available only at indexes higher than 1.5. In such event our customer service will contact you to inform about additional fee for a higher index.


What do I need to order prescription glasses?

Before you order, you’ll need a valid eyeglasses prescription (make sure it’s not for contacts!) and your pupillary distance (PD). Your PD is the distance in millimeters between your pupils, and helps us center your prescription correctly in your frames. If your doctor did not include your PD on your prescription, you can measure it using our instructions.

You can also stop by any of our retail partners and measure your pupillary distance there.

Once you have your PD, you can either hand-write it onto the copy of your prescription before scanning or submit the measurement to info@sireneeyewear.com.


How do I order multiple pairs of glasses with different prescriptions?

If you are interested in purchasing multiple pairs using different prescriptions (e.g. one for you and one for your girlfriend or boyfriend; one pair for distance and one for reading), please place a separate order for each prescription. Shipping is always free, so don’t worry about getting charged extra for the separate orders.

Is this frame the right one for me?

At Sirène we think your unique personality should shine through your frames. We believe we have something for everyone out.


Can you help me pick out a frame?

Finding the right pair of frames can be tricky, but our personal stylists are here to help every day. Email your portrait picture to info@sireneeyewear.com and tell us what you look for. We will be there to help you to choose the best frames for you.


How do I know if a frame fits me?

Are they comfortable? That’s a great start. Otherwise, a few rules of thumb:

  • Pupils should be near the center of the lens
  • Lenses shouldn’t extend past the side of your face
  • Eyebrows should not be inside the glasses
  • When you smile, your cheeks don’t push the frames up
  • Frames shouldn’t slide down your nose


What if my frame doesn’t fit quite right?

If you find a frame you love but it doesn’t fit quite right you can adjust the below issues in most optical shops for free or for small fee:

  • If the frames are too tight or loose behind your ears
  • The temples are too long or too short
  • The temples are too tight or loose at the side of your face
  • The frames are crooked or slide down your face


Where can I find my frame’s measurements?

All of our frames have a few numbers printed on the inside of the temple arm. These refer to the lens width, bridge width, and temple arm length of your frames. On each product page, the frame measurements are presented as a technical drawing. We recommend comparing the measurements of your current glasses to the frame measurements on our website; this will give you an idea for how a pair will fit you.


Shipping and delivery


When can I expect my order?

The processing time depends on several things: the type of order, whether your order is complete (Do we have your prescription and PD?), and when you place it.

Estimated delivery times of frames without prescription lenses are:

Europe: 2-5 business days

How much longer does it take to deliver frames with corrective lenses?

If corrective lenses are selected, the shipment time will be extended by the period required to prepare your lenses. In most cases this is 3 business days, but for more complex orders, processing a prescription may be extended to up to 21 business days.
