Made in an optical laboratory

Our optical laboratory

New lenses for the frames you already own are prepared by opticians at the independent Della Spina optical laboratory. From the frame check to final inspection, the work stays with a team that prepares and fits lenses every day.

Your frames, step by step

What happens to your frames?

Every frame and order is assessed individually. If you are unsure whether your frames are suitable before sending them, share a photo and your prescription details with us.

  1. Frame assessment

    An optician first checks the condition and suitability of your frames together with the order details. If anything needs your decision, we contact you before continuing.

  2. Lens preparation and edging

    We prepare your chosen lenses using the order information, then edge them precisely to fit the shape of your frames.

  3. Fitting and final inspection

    We fit the lenses into your frames and inspect the finished glasses before packing them for tracked return shipping.
