It is undoubtedly one of the fashion houses with the most history and success in the world. It was founded by Christian Dior in 1946 in Paris at 30 Avenue Montaigne. At the beginning of 1947, Dior launched its very first collections of clothes and perfumes. Since that year, a succession of successes has marked the maison, making it today the ultimate representation of luxury. In April 2017, Christian Dior was acquired by the LVMH group.

In the field of eyewear, Dior has been present for decades, creating icon after icon and establishing itself as a trendsetter. The production of Dior branded glasses until 2020 was in the hands of the Safilo group, but due specifically to the acquisition by the LVMH group, from 2021, production passed to Thélios, a company born from the LVMH group's desire to enter the eyewear sector and Marcolin Groups experience in creating unique frames that faithfully combine Italian design and craftsmanship with the core values of each house.

A synthesis of the names of the Greek gods Theia, goddess of light and sight, and Helios, god of the sun, Thélios covers the entire production cycle of eyewear, handling the design, production, and worldwide distribution of sunglasses and optical frames for several Houses within the LVMH portfolio   As an emblem of quality and excellence at all levels, in product, service, communication, and distribution.
