Did You Know Who Invented Contact Lenses?

Who Invented the Contact Lens

Although the idea of correcting vision by placing a lens on the eye can be traced back to ancient times, the invention of the contact lens as we know it today was a much more recent development. In this article, we will explore the history of vision correction methods, the first contact lens invention, and the different types of contact lenses that have been developed over the years.

The Early Vision Correction Methods

Before the invention of contact lenses, people had to rely on various methods to correct their vision. One of the earliest methods was the use of magnifying glasses. These glasses could be placed on top of a book or newspaper to make the text appear larger and easier to read. Another method was the use of spectacles, which consisted of two lenses mounted on a frame that rested on the nose. Spectacles were not very practical, as they had to be constantly adjusted and were prone to falling off the face.

In the 19th century, a new vision correction method was developed – the use of corneal lenses. These were lenses made of glass or plastic that were placed directly on the cornea of the eye. The idea was to correct vision by changing the shape of the cornea. However, corneal lenses were uncomfortable to wear, and they often fell off the eye.

First Contact Lens Invention

The first contact lens as we know it today was invented by a German ophthalmologist named Adolf Fick in 1887. Fick's lens was made of glass and was designed to cover the entire cornea. It was an uncomfortable and impractical design, as the lens had to be custom-made for each patient's eye and was difficult to fit.

A few years later, another ophthalmologist named Eugen Fick (no relation to Adolf Fick) developed a softer and more flexible contact lens made of rubber. However, these lenses were still uncomfortable to wear and could only be worn for short periods of time.

It wasn't until the 1950s that contact lenses became more widely available and comfortable to wear. Pioneers in the industry such as William Feinbloom, Kevin Tuohy, and Otto Wichterle helped to develop new materials, designs, and manufacturing techniques that made contact lenses more practical, affordable, and comfortable.

Types of Contact Lenses over the Years

Since the first invention of the contact lens, various types of lenses have been developed. Here are some of the most significant types and their inventors:

  • Gas-permeable lenses: In the 1970s, scientist Norman Gaylord developed a new type of contact lens that allowed oxygen to pass through the lens material. These lenses, known as gas-permeable lenses, were much more comfortable to wear than previous rigid lenses.
  • Soft lenses: In the 1960s, Czech chemist Otto Wichterle invented a new type of contact lens made of hydrogel material. Soft lenses were much more comfortable to wear than previous hard lenses and quickly became popular among contact lens wearers.
  • Toric lenses: In the 1970s, Kevin Tuohy developed a new type of contact lens designed to correct astigmatism. These lenses, known as toric lenses, were shaped differently than standard lenses to correct the irregular shape of the eye that causes astigmatism.
  • Disposable lenses: In the 1980s, William Feinbloom invented the first disposable contact lens. Disposable lenses are designed to be worn for a short period of time and then discarded, eliminating the need for cleaning and care.
  • Colored lenses: In the 1980s, the first colored contact lenses were introduced. These lenses were designed to change the color of the eye for cosmetic purposes.

Today, there are many different types of contact lenses available, each with its own unique design and purpose. Thanks to the innovations of pioneers in the field, contact lenses have become a practical, comfortable, and affordable vision correction option for millions of people around the world.

How Contact Lenses Work

For many people, contact lenses are a comfortable and effective alternative to eyeglasses. They are worn directly on the eye's surface and conform to the curvature of the cornea to correct refractive errors, such as nearsightedness, farsightedness, and astigmatism. This allows light to focus correctly on the retina and improves vision. But have you ever wondered how they work?

Contact lenses work by altering the path of light as it enters the eye. They are made up of two main components: the lens material and the prescription. The prescription is custom-made for each wearer, taking into account their specific eye measurements and vision needs.

Main Components of Contact Lenses

The base curve is the curvature of the back surface of the lens and must match the curvature of the cornea for a proper fit. The diameter of the lens should be large enough to cover the cornea but not too large as to interfere with blinking and eye movement. The power is the measurement of the lens needed to correct the specific refractive error.

The lens material also plays a crucial role in how contact lenses work. Early contact lenses were made of glass, but today they are made of soft, flexible plastic materials that allow oxygen to pass through to the cornea. This is essential for corneal health, as the cornea gets its oxygen supply from the air.

Contact Lenses vs Glasses

Compared to eyeglasses, contact lenses offer several advantages. For one, they provide a wider field of view and more natural vision since they move with the eye. They are also less likely to fog up in cold weather or get splattered with raindrops. Many people find them more aesthetically pleasing since they don't obscure the face or change the appearance. They are also ideal for people who engage in physical activities since they don't get in the way of helmets, goggles, or other gear.

On the other hand, contact lenses require more maintenance and care than eyeglasses. They must be cleaned and disinfected regularly and replaced according to a specific schedule to prevent infection or damage to the eyes. They are also more expensive than eyeglasses, especially if they are used daily.

Overall, the choice between contact lenses and eyeglasses comes down to personal preference, lifestyle, and budget.

Caring for Contact Lenses

Proper care and maintenance for contact lenses are essential for eye health and longevity. Here are some tips for caring for contact lenses:

  • Wash your hands thoroughly before handling contact lenses
  • Use only contact lens cleaning solutions recommended by your eye doctor
  • Replace contact lens cases every 3 to 6 months
  • Don't wear lenses longer than the recommended wearing time, even if they feel comfortable
  • Avoid exposing lenses to water or swimming with them
  • Remove lenses before going to bed

By following these tips, you can help prevent eye infections and ensure that your contact lenses provide clear and comfortable vision.

Now that you know how contact lenses work, you can make an informed decision about whether they are right for you. Whether you choose to wear contact lenses or eyeglasses, it's essential to have regular eye exams to maintain eye health and detect any vision problems.
