Glasses are among one of the most popular needs of Americans with 184 million owning a pair. That’s roughly 64% of our nation’s population. The need for glasses range from far- and nearsightedness to astigmatism. Eyewear tech received subtle, yet dramatic changes between the 18th and 21st centuries, but there has always been room to grow. While eyeglasses are such an old technology at this point we rarely think of them as technology, credit for the advancements that have been made in recent decades is wholly owed to the scientific community. The future of eyewear is now completely in the hands of technology, and there are some exciting advancements coming down the line.
