Bifocals, invented by Benjamin Franklin in the 18th century, significantly impacted society by improving the quality of life for individuals with presbyopia, a common age-related vision condition. They allowed wearers to see clearly at both near and far distances without the need to switch between different pairs of glasses, enhancing daily activities such as reading, working, and socializing. This innovation contributed to greater independence for older adults and facilitated their continued engagement in education and the workforce, ultimately influencing productivity and social participation. Additionally, bifocals set the stage for further advancements in eyewear technology.
