Theo launched a new limited edition of its Mille+50 collection of corrective frames, called Half and Half, at this year's Silmo show in Paris. The collection, made of titanium and metal with gold palladium, consisting of six different styles, is limited to 50 frames per style and priced at €1000 for end consumers. The golden models are made of 3 ?m palladium with a layer of 4 ?m gold on top and have a hallmark in the temple to show that it's real 24-carat gold. Theo is also releasing the same three models in a color scheme that combines black with silver. These models have a layer of 3 ?m palladium. The frames were already for sale during the Silmo show last month and are now for sale at selected opticians.
