On May 23, 1785, Benjamin Franklin announced his invention of bifocal glasses, a significant development in optical technology. Franklin, a polymath known for his contributions to science, politics, and literature, designed the bifocals to correct both nearsightedness and farsightedness simultaneously. This innovation not only enhanced the quality of life for those with vision impairments but also showcased Franklin’s ingenuity and his lifelong pursuit of practical solutions to common problems.
