Ologies with Alie Ward: Bonus Episode on Optical Technology Release Date: August 1, 2025

In this special bonus episode of Ologies, Alie Ward delves into the fascinating world of optical technology, exploring the rich history of eyeglasses and the current state of modern-day vision. This episode features insightful conversations with Jenny Benjamin, the Director of the Museum of the Eye in San Francisco, and Dr. Nadia Sledge, a practicing optometrist in Houston, Texas. Together, they unravel the evolution of eyewear, the science behind vision correction, and the challenges posed by the digital age.

1. Exploring the History of Eyeglasses with Jenny Benjamin

Early Origins and Invention Jenny Benjamin sets the stage by tracing the origins of eyeglasses back to around 1286. She highlights the establishment of a lens-manufacturing guild in Venice, Italy, in the early 1300s. Despite existing depictions, such as Cardinal Hugh of Provence supposedly wearing glasses in a 1352 painting—a historical inaccuracy since he died in 1263—eyeglasses quickly became symbols of learnedness and wisdom.

Jenny Benjamin [07:19]: "Eyeglasses meant you were learned. Right. So a priest, so you've, you know how to read, probably to write."

Evolution of Eyewear Designs Jenny discusses the transformation of eyeglasses from practical tools to fashion statements. The introduction of bifocals by Benjamin Franklin marked a significant advancement, allowing users to see both near and far without switching lenses. Over the centuries, designs became more sophisticated, leading to the creation of lorgnettes—handheld glasses popular in the late 18th century.

Jenny Benjamin [25:03]: "I really love is actually our collection of lorgnettes. And lorgnettes are handheld eyeglasses."

Cultural Significance and Stigmas Historically, wearing glasses was often stigmatized, associated with infirmity and age. Jenny reflects on how perceptions have shifted, noting that from the 1300s to the mid-20th century, glasses were more a sign of intellectualism and wisdom rather than a fashion accessory.

Jenny Benjamin [17:14]: "Glasses as we know them weren't widespread until about 100 years ago, and they definitely were not cool before that."

Manufacturing and Accessibility The production of eyeglasses has evolved from handcrafted precision instruments to mass-produced, affordable items. Jenny explains how early eyeglasses were expensive, often sold by jewelers, making them accessible primarily to the affluent. The advent of metal frames and standardized manufacturing processes in the 19th century democratized access.

Jenny Benjamin [19:08]: "We're talking about cheap frames available. They're made out of metal, base metal, and it's just a simple pair of lenses."

2. Modern Day Vision and Eye Health with Dr. Nadia Sledge

Impact of the Digital Age on Vision Dr. Nadia Sledge discusses the alarming rise in myopia (nearsightedness) among children, attributing it to increased screen time and reduced outdoor activities. She emphasizes that by 2050, half of the world's population is expected to be nearsighted.

Dr. Nadia Sledge [32:12]: "By 2050, it is anticipated that half of the world will be nearsighted."

Importance of Regular Eye Exams Highlighting the necessity of annual eye examinations, Dr. Sledge explains that regular check-ups are crucial not only for vision correction but also for detecting systemic diseases that manifest in the eyes.

Dr. Nadia Sledge [30:47]: "There is over 270 systemic diseases that we can diagnose in the eye itself."

Myopia Management and Preventative Measures To combat the rise in myopia, Dr. Sledge advocates for the "20-20-20 rule"—every 20 minutes, look at something 20 feet away for 20 seconds. Additionally, she encourages increased outdoor time to reduce the progression of nearsightedness in children.

Dr. Nadia Sledge [40:48]: "Every 20 minutes, look 20 feet away for 20 seconds just to give your eyes a little bit of a break."

Advancements in Eyewear Technology The conversation moves to modern eyewear innovations, such as polarized lenses, which reduce glare by blocking horizontal light waves. Dr. Sledge explains the practical applications of polarization in activities like driving and water sports.

Dr. Nadia Sledge [37:01]: "Polarization is basically a filter that decreases that reflective glare."

Debunking Online Eye Exams Addressing the rise of online eye exams, Dr. Sledge underscores their limitations, emphasizing that comprehensive in-person evaluations are essential for accurately assessing eye health and vision.

Dr. Nadia Sledge [44:27]: "There is no way that anybody on an online eye exam can tell you that your eyes are actually healthy."

Practical Tips for Glasses Care Dr. Sledge shares practical advice on maintaining and safeguarding glasses. Her mantra, "If they're not on your face, they're in the case," serves as a simple yet effective strategy to prevent damage or loss.

Dr. Nadia Sledge [45:48]: "If they're not on your face, they're in the case. That might work for adults as well as kids."
