In the 1970s, we began seeing much larger eyeglasses, eg Gloria Steinem. I believe this was enabled by the development of lower weight high redaction polymer lenses - fashion intersects with applied chemistry. ???

Yes — you're exactly right that the dramatic shift to larger eyeglasses in the 1970s, such as the iconic oversized frames worn by Gloria Steinem, was not only about fashion trends, but was also enabled by technological advancements in optical materials, especially in lighter, higher-index plastics.
Here's how fashion intersected with applied chemistry:
🧪 Material Innovation
Prior to the 1970s, most prescription lenses were made from glass, which was:
-
Heavy (especially for large lenses)
-
Prone to shattering
-
Thick, especially for stronger prescriptions
In the late 1960s and early 1970s, CR-39, a polymer developed by PPG Industries, began to take off. It was:
-
Much lighter than glass
-
Easier to mold and tint
-
More impact-resistant, safer than glass
Soon after, high-index plastic lenses began development:
-
Allowed thinner and lighter lenses for high prescriptions
-
Made larger lens areas more feasible without excessive weight
These polymers were often based on polycarbonate or urethane compounds, and their optical properties (including high refractive index) meant less material was needed to achieve the same corrective power.
👓 Fashion Synergy
-
The 1970s brought a new aesthetic: bold, expressive eyewear became a statement rather than just a necessity.
-
Large frames could now be worn comfortably by people with strong prescriptions — not previously possible with thick glass.
-
Designers like Halston and brands like Ray-Ban and Pierre Cardin incorporated these larger lenses into their fashion-forward offerings.
-
Public figures like Steinem, Diane Keaton, and Jacqueline Kennedy Onassis helped normalize and popularize the oversized look.
🔄 Feedback Loop
Fashion demanded big lenses → Chemistry made them possible → Consumers adopted the trend → Chemistry evolved further to accommodate comfort, tints, coatings, and more.
So yes — the 1970s oversized eyewear boom was as much about chemistry as about culture, with optical polymer science literally making the look wearable.

Plan a sequel.
Photosensitive glasses were invented when?
But they remained somewhat dark indoors, limiting their popularity to a few geeky tech nerds, often with pocket pen holders.
Later, they improved and were transparent indoors, leading to a surge in popularity even in the fashion aware.

Excellent direction — the sequel would explore how one of the most misunderstood and quietly evolving optical technologies — photochromic lenses (a.k.a. Transitions lenses) — went from a nerdy curiosity to a mainstream fashion staple. Here’s a concept and outline for the sequel documentary and book:
🎬 Sequel Documentary Title (and Book Title):
Fade to Clear: The Rise, Fall, and Reinvention of Photochromic Glasses
Subtitle: How Self-Tinting Lenses Went from Geek Chic to Global Fashion
🌤️ Overview:
In the 1970s and 1980s, photochromic lenses—glasses that darken in the sun—were a technological marvel that never quite caught on. Indoors, they stayed annoyingly tinted; outdoors, they didn’t always darken fast enough. Associated more with engineers, pocket protectors, and suburban dads than with chic style, they became shorthand for function over form.
But after decades of scientific refinement, the chemistry caught up with the fashion. Modern photochromics are responsive, nearly invisible indoors, and stylish enough for runway collaborations. Fade to Clear tells the little-known story of this optical comeback, exploring how material science, human behavior, and cultural perception evolved in tandem.
📚 Proposed Book / 3-Part PBS Documentary Structure
EPISODE 1 / CHAPTER 1: “A Lightbulb Moment: The Invention of Photochromics”
-
The story begins in 1960s laboratories: the first glass photochromic lenses were invented by Corning in 1966.
-
These relied on silver halide crystals embedded in the glass, which darkened in UV light and returned to clear in its absence.
-
They were expensive, slow to clear, and stayed visibly tinted indoors.
-
Their early adopters were often science professionals, engineers, and opticians—function-first users.
Key theme: A brilliant invention ahead of its time—technically fascinating, aesthetically awkward.
EPISODE 2 / CHAPTER 2: “The Nerdy Years: Tint That Never Left”
-
Throughout the 70s, 80s, and even 90s, photochromic glasses remained the butt of jokes.
-
Persistent indoor tinting led to mockery: wearers were seen as out-of-touch or unconcerned with fashion.
-
Plastic photochromics arrived in the 1980s–90s but were initially inferior to glass in UV responsiveness and longevity.
-
Pop culture references often painted photochromic wearers as aging, techy, or socially awkward.
Key theme: How a visual quirk became a cultural stereotype.
EPISODE 3 / CHAPTER 3: “Fade to Clear: A Chemical and Cultural Renaissance”
-
By the early 2000s, new generations of photochromic technology (especially the Transitions® brand) overcame the hurdles:
-
Clearer indoors
-
Faster transition times
-
Better UV responsiveness even behind windshields
-
More options: brown, grey, blue, mirrored
-
-
Marketing partnerships with Oakley, Ray-Ban, and even fashion houses followed.
-
Optical science met lifestyle branding: transitions were no longer a punchline—they were a feature.
Key theme: The comeback story — how chemistry, branding, and fashion finally aligned.
Epilogue: “The Future Is Adaptive”
-
Smart lenses that adjust not just to light but to temperature, time of day, or user preference
-
Photochromics as precursors to next-gen AR/VR optics and smart contact lenses
-
What it means to wear adaptive, intelligent eyewear — and how society will see that.
