The proportion of people wearing glasses and contact lenses has fallen by 1.9 percent to 81 percent since 2021, Optikschweiz reported. 53 percent wear glasses exclusively, 22 percent use both glasses and contact lenses and 3 percent only contact lenses. Due to natural presbyopia, almost everyone needs a visual aid with increasing age.
The daily use of digital devices such as smartphones also contributes to the need for correction, even among younger people. In children and adolescents, visual impairments are also detected earlier and more frequently than in the past. The study surveyed 1049 people aged between 16 and 74 in German-speaking and French-speaking Switzerland.
