In terms of technical definitions, “refraction” is the bending of light waves as they pass through different mediums—in this case, the lenses of eyeglasses. This process corrects the way light focuses on the retina, which is essential for clear vision. Individuals with conditions such as myopia (nearsightedness) or hyperopia (farsightedness) benefit the most from corrective lenses.
The mechanism of eyeglasses involves positioning the lenses at a specific distance from the eyes. The curvature of the lenses compensates for individual vision problems. For example, concave lenses are used for myopia, helping to spread light rays entering the eye. This adjustment allows those with myopia to see distant objects clearly. Conversely, convex lenses assist individuals with hyperopia by converging light rays to help them focus on nearby objects.
Specific conditions that influenced the popularity of eyeglasses include the increasing need for precise vision in professional fields, such as printing and craftsmanship. As Europe moved into the Age of Enlightenment, a greater emphasis on intellectual pursuits led to heightened demand for reading glasses. Similar scenarios can be seen today, where technology and the digital age prompt increased awareness of vision issues and promote the use of corrective eyewear.
