Sienna Size & Fit FAQs

How low-profile is Sienna’s rectangular front?

The frame-height reference is 40 mm. Compare it with a deeper pair if you prefer a shallower outline.

How wide is Sienna across the face?

Its overall front is marked 142 mm. Use that full span separately from the 52 mm lens width.

Is Sienna’s bridge the same size as Isla’s?

Both are marked 18 mm. Compare the pictured nose openings too, especially if you have a favourite resting position.

Will Sienna’s broad arms reach like a longer pair?

They are marked 138 mm. Compare that length and the curved tips with your current side fit.

Does Sienna’s slim description mean a very narrow frame?

The 142 mm overall width is the practical size reference. The shallower silhouette describes a different part of its proportions.
