Open frame glasses with a particularly striking and fully customizable look. Foldable temples in a flexible and practically indestructible material: Grilamid TR90™, a technopolymer produced in Switzerland by the multinational EMS Grivory. The interchangeable nose piece has special grooves for sweat escape, so that the glasses do not fall on the nose. It is also adjustable in width for a perfect fit. The FullRevo™ red non-interchangeable monochrome fixed lens is a cylindrical type, that is, it focuses the light by reflecting the image in a vertical line instead of a single point like normal spherical lenses. Another very particular feature of these glasses are the upper and lower edges that can not only be removed to have glasses with a more conical shape, but can also be exchanged and replaced to personalize them.
