Bifocals, in brief, are lenses with two different strengths, allowing for both close and distance viewing without the need to switch from one pair of glasses to another.
While historians are split about whether Benjamin Franklin actually invented them or not, the fact remains today that they are indispensable for anyone seeking vision correction for myopia (nearsightedness), hyperopia (farsightedness), and/or astigmatism (oval-shaped eyes), together with presbyopia (“old sight” – reading difficulty that begins between ages 35 and 45).
Bifocals use modern technology to split the lenses in different ways, and to allow the lenses to be thinner, more durable, and more stylish than in the past.
