EssilorLuxottica SA is a Franco-Italian vertically integrated multinational holding company registered in Charenton-Le-Pont and headquartered in nearby Paris.

It was founded on 1 October 2018 and its name is an amalgamation of the two major corporations which merged to create it; the French Essilor and the Italian Luxottica.

The first few years of EssilorLuxottica post-merger were marred by disputes over leadership roles, but Del Vecchio was able to bring them to a satisfactory end.

Essilor and Luxottica were respectively the world's leading manufacturers of ophthalmic lenses and of eyeglasses; upon the merger, EssilorLuxottica thus became the juggernaut of the eyewear industry, which some critics have qualified of near monopoly.

Sagnières responded to Del Vecchio by accusing the Luxottica founder of attempting to take control of the newly formed conglomerate without offering "a premium to shareholders" of EssilorLuxottica.

The terms of the merger provided that old Essilor leadership as well as Luxottica's officers would have equal control over the merged entity, though the company would select a new CEO, internally or externally, by the end of 2020.

A company statement to the Financial Times reflected the settled nature of the conflict, stating that the resolution of the leadership battle represented "the victory of a vision, the creation of an extraordinary business that is at the beginning of what it can achieve".

This was the first major strategy shift and industry expansion for the company after Del Vecchio's 2022 death, and it accompanied reports that the firm was planning to introduce hearing aid technology into its lenses.
