The bifocal lens system that Benjamin Franklin created was not perfect. What evidence from the passage supports this conclusion? “Franklin created dual-lens eyeglasses, which offered a bottom half to correct one’s vision of close-by objects and words, and a top half enabling the same viewer to see far away.” “New users can experience headaches or dizziness when first wearing them.” “This solution also made it possible to tailor the prescription of each lens to accurately correct the vision of the wearer.” “He did this by cutting the two different necessary lenses in half and combining them.”
