The Titan Minimal Art glasses model by Silhouette has established a special relationship with astronauts, having accompanied them for over 20 years in 69 space missions, for an incredible total of 86,762 hours in space, equivalent to almost 10 years. Its ultra-light structure without hinge or screws, along with just 1.8 grams in weight, is in fact ideal for missions into space as it reduces potential harm for astronauts posed by traditional glasses whose screws and small parts risk becoming detached and floating off into somewhere they shouldn’t be.
