Glass
Glasses are one of humanity’s greatest inventions because they bridge the gap between physical limitation and full participation in society. For centuries, poor eyesight could mean exclusion from education, reduced job opportunities, or even physical danger, but glasses provide an immediate, non-invasive solution that restores independence and enhances quality of life. They have driven scientific progress, from scholars in the Renaissance to modern-day researchers, ensuring that vision impairments do not limit human potential. Beyond their functional role, glasses also serve as a fashion statement and can protect against environmental hazards like UV rays or digital eye strain. Their impact is so profound that we often take them for granted, yet without them, the world would be far less accessible for millions.
