Yes – with single-vision glasses, thin 1.61 lenses are included in the price of the frames at no extra cost.
One pair of single-vision glasses costs €99 (standard frames), €119 (titanium frames) or €139 (rimless frames) – that includes the lenses, a scratch-resistant coating and an anti-reflective coating.
Progressive lenses cost an extra €50 per pair, so one pair of progressive glasses starts at €149.
Extra features (thinner 1.67 or 1.74 lenses, blue-light filter, photochromic lenses, tints, polarisation) always cost extra.
