Find your fit

Look for the three numbers inside the temple of your current glasses: lens width, bridge width and temple length. Compare them with these measurements. The frame shape and nose fit matter as much as the numbers.

About this frame

On the Kuboraum K5 Ossidiana, the black surface has an uneven texture that becomes clearer up close. The front retains the K5 cat-eye shape, with its upper edge extending towards the temples.

Look at it from a three-quarter angle too: the profile and surface give the same shape a different expression. An acetate optical frame, designed in Berlin and handmade in Italy.

All Kuboraum optical frames · The ideas behind the Masks.

KUBORAUM calls its frames “masks”. The idea is that eyewear can change how we see ourselves and how we present ourselves to others: an object through which to play, recognise ourselves and express different aspects of our personality.

The name evokes a cubic room, a personal space in which to feel at ease and free to be ourselves. This image shapes the brand’s approach, treating the frame as a place to inhabit, close to the face and to individual identity.

A frame is best understood when you try it on.

In the boutique, we look at proportions, how the frame rests on your nose and the length of the temples. Trying it on helps you see how it suits your face and lets us adjust it with care.

As a SEIKO Vision Specialist, we start with your prescription and daily habits to discuss lenses, centration and fitting. We explain the options and prepare a personalised quote before proceeding.
