Key Takeaway
Contact lenses have evolved from Leonardo da Vinci's 16th-century concepts to today's comfortable daily disposables. What began as large glass shells in 1888 has transformed into ultra-thin, breathable lenses made from advanced materials. Modern contact lenses available at Bella Lense represent over 130 years of continuous innovation in vision correction technology.
The history of contact lenses is far more fascinating and extensive than most people realize. While many assume contact lenses are a modern invention, their origins trace back centuries, involving brilliant minds, groundbreaking materials, and countless innovations that have revolutionized how we correct vision problems.
The Early Conceptual Origins of Contact Lenses
Leonardo da Vinci's Revolutionary Vision (1508)
The story of contact lenses begins with one of history's greatest innovators. In 1508, Leonardo da Vinci described the fundamental concept that would eventually become contact lenses in his "Codex of the Eye." Da Vinci theorized that vision could be altered by placing the eye in direct contact with water, essentially proposing the first concept of changing the eye's refractive properties through direct contact.
Da Vinci's sketches showed a person's face submerged in a glass bowl filled with water, demonstrating his understanding that vision could be modified through different mediums. While impractical, this concept laid the theoretical groundwork for what would eventually become contact lens technology.
René Descartes and the First Practical Design (1637)
French philosopher and mathematician René Descartes took da Vinci's concept further in 1637. Descartes proposed placing a liquid-filled glass tube directly against the eye to correct vision problems. His design included a tube that would rest against the cornea, filled with liquid to create the necessary refractive changes.
Though Descartes' design would have made blinking impossible and was entirely impractical for daily use, it represented the first genuine attempt to create a wearable vision correction device that made direct contact with the eye.
The Birth of Modern Contact Lenses
Adolf Fick's Groundbreaking Achievement (1888)
The year 1888 marks the official invention of the first contact lens that could actually be worn. German ophthalmologist Adolf Fick created the first successful contact lens, which was made from heavy brown glass. These early lenses were large, covering the entire visible portion of the eye, and could only be worn for a few hours due to their weight and the lack of oxygen permeability.
Fick's lenses were groundbreaking for several reasons:
-
They were the first to successfully correct vision through direct eye contact
-
They introduced the concept of custom fitting for individual eyes
-
They demonstrated that the human eye could tolerate a foreign object for extended periods
Early Glass Contact Lenses and Their Limitations
Following Fick's success, several other inventors and eye care professionals began experimenting with glass contact lenses. These early versions faced significant challenges:
Material Limitations:
-
Heavy weight caused discomfort and eye fatigue
-
No oxygen permeability led to corneal damage
-
Fragility made them dangerous if broken while wearing
-
Size and thickness limited wearing time to just a few hours
Manufacturing Challenges:
-
Each lens required individual crafting by skilled artisans
-
Fitting required extensive trial and error
-
Cost made them accessible only to wealthy patients
-
No standardization existed across different manufacturers
The Plastic Revolution in Contact Lenses
Kevin Tuohy's Plastic Innovation (1948)
The next major breakthrough came in 1948 when American optometrist Kevin Tuohy developed the first plastic contact lenses. Tuohy's innovation addressed many problems of glass lenses:
-
Lighter weight: Plastic lenses were significantly more comfortable
-
Improved durability: Less likely to shatter and cause eye injury
-
Better fitting: Could be molded more precisely to eye shape
-
Extended wear: Patients could wear them for longer periods
Tuohy's lenses were made from polymethyl methacrylate (PMMA), a clear, rigid plastic that became the standard material for contact lenses for the next several decades.
The Development of Corneal Lenses
Tuohy's design also introduced the concept of corneal lenses – smaller lenses that covered only the cornea rather than the entire visible eye. This innovation provided several advantages:
-
Reduced foreign body sensation
-
Improved comfort during blinking
-
Better tear circulation around the lens
-
More natural eye movement and function
The Soft Contact Lens Revolution
Otto Wichterle's Hydrogel Breakthrough (1959)
Czech chemist Otto Wichterle made perhaps the most significant advancement in contact lens history when he invented soft contact lenses in 1959. Working with his colleague Drahoslav Lím, Wichterle developed a water-absorbing plastic called hydrogel, specifically poly-hydroxyethyl methacrylate (pHEMA).
Revolutionary Properties of Hydrogel:
-
High water content (up to 38% in early versions)
-
Flexible and comfortable material
-
Better oxygen permeability than rigid plastics
-
More biocompatible with eye tissues
Wichterle's first soft contact lenses were created using a incredibly resourceful method – he used his wife's jewelry-making kit and a children's building set to create the first spin-casting machine for contact lens production.
Bausch & Lomb's Commercial Success
In 1971, Bausch & Lomb acquired the rights to Wichterle's soft contact lens technology and introduced the first commercially successful soft contact lenses in the United States. This marked the beginning of widespread contact lens adoption, as soft lenses offered:
-
Immediate comfort for new wearers
-
Reduced adaptation period
-
Lower risk of lens loss during physical activities
-
More forgiving fitting requirements
Modern Contact Lens Innovations
Daily Disposable Contact Lenses
The introduction of daily disposable contact lenses in the 1990s represented another revolutionary step. These lenses eliminated many hygiene and maintenance concerns while providing:
-
Ultimate convenience: No cleaning or storage required
-
Optimal hygiene: Fresh lens every day reduces infection risk
-
Consistent performance: No protein buildup or deposits
-
Travel-friendly: No need for solutions or cases
Today's daily disposable lenses available through retailers like Bella Lense represent the pinnacle of comfort and convenience in vision correction.
