A lot of changes have occurred in the world of eyewear from 1970 to the present. MIDO has written its transformative history over the course of these 50 years. At the first edition, there were 95 exhibitors (67 Italian and 28 from other countries) who displayed their products in 3.000 m2 of exhibit space. In 2019, more than 1.320 exhibitors and their wares occupied 7 pavilions and represented 70 countries. A growth pattern benefiting from an ongoing legacy of leadership built over time that, in only the last 5 years, has brought a 20% increase in attendance, which peaked at the last edition with nearly 60.000 attendees from 159 countries.
