Did You Know Contact Lenses Were Invented Over 500 Years Ago?

The Invention of Contact Lenses

Early Attempts at Corrective Lenses

The idea of contact lenses dates back to the early 16th century when the great Leonardo da Vinci first hypothesized the concept of placing a corrective lens on the cornea of the eye to improve vision. However, it wasn't until 1801 that the first glass contact lens was invented by Thomas Young. Despite its significance at the time, the lens was heavy and uncomfortable to wear.

The Birth of Modern Contact Lenses

It wasn't until nearly a century later that German physicist F.E. Muller invented the first modern contact lens made entirely of glass in 1887. Unlike the earlier lens, this latest version could be worn directly on the cornea, improving vision significantly. However, the glass lenses were fragile, and wearers needed to upgrade them frequently, which made them costly to maintain.

A more comfortable and durable version was introduced by William Feinbloom in 1936. He used a plastic contact lens made from polymethyl methacrylate (PMMA), which was more comfortable to wear and less brittle than the glass ones. This type of contact lens was popular in the following years, but it was not ideal as PMMA didn't allow for oxygen to pass through, causing eye irritation and other discomforts.

Advancements in Contact Lens Technology

The introduction of soft contact lenses made of hydrogels revolutionized the world of contact lenses in the 1950s and 1960s. Czech chemist Otto Wichterle created soft contact lenses, made using the latest hydrogel materials, which made it easier to wear than previous models.

Gas-permeable lenses were invented in 1971 by another Czech chemist, Jan Evangelista Purkinje. The gas-permeable contact lenses allowed more oxygen to penetrate the lens, which resulted in more comfortable and healthier contact lenses.

Over the years, a lot of improvements have been made to contact lenses to increase their oxygen permeability, durability, and comfort. Modern contact lenses are made with the latest materials that make it possible to apply them easily, reduce or eliminate vision issues such as nearsightedness, astigmatism, etc.


The invention of contact lenses was a significant milestone in improving vision for everyone. From the early glass lenses to the modern ones, we have seen the technology evolve. Today's contact lenses are a far cry from the early models but are still evolving with new and improved technologies that promise even more comfortable and effective solutions for vision deficits. Nowadays, contact lenses have become an essential accessory for many, and one can choose from a variety of lenses based on their preferences and requirements.

The Impact of Contact Lenses

A Revolutionary Solution for Vision Correction

Contact lenses were first invented in the late 19th century by a German glassblower named F. E. Muller. These early contact lenses were made of glass and were heavy and uncomfortable to wear. The first plastic contact lenses were invented in 1936 by William Feinbloom, an optometrist from New York. Feinbloom's lenses were made of a special type of plastic called polymethyl methacrylate (PMMA), which was lighter and more comfortable than glass. These lenses were the forerunners of the soft contact lenses that are used today.

Contact lenses have become a popular alternative to glasses for vision correction due to their convenience, comfort, and discreetness. Unlike glasses, contact lenses do not interfere with daily activities such as sports and other physical activities. They also provide a wider field of vision and a more natural look, which can boost confidence and self-esteem.

Boosting Performance and Confidence

Athletes and performers use contact lenses as a practical solution to improve their performance. Contact lenses provide a more secure and stable fit when engaged in activities that require movement, such as running, dancing, or playing sports. Contact lenses also eliminate the risk of glasses falling off or breaking, making them a safer option for these activities. Additionally, contact lenses can provide a more aesthetically pleasing appearance, which can boost confidence and self-esteem in these individuals.

Improving Eye Health

The latest technology in contact lenses has greatly improved eye health. Modern contact lenses can be made of materials that allow more oxygen to pass through to the cornea, reducing the risk of corneal problems. Some contact lenses now also incorporate UV protection, which can help reduce the risk of eye damage from UV radiation exposure. Contact lenses can also help address certain eye conditions. For example, some contact lenses are specifically designed to slow down the progression of myopia, or nearsightedness. Others can help correct vision problems associated with aging, such as presbyopia.

In conclusion, contact lenses have come a long way since their invention in the late 19th century. They offer a convenient, comfortable, and discreet solution for vision correction that can improve overall quality of life. Contact lenses also have the added benefits of boosting performance, confidence, and improving eye health through advanced technology.

The Future of Contact Lenses

Since their invention in the late 19th century, contact lenses have come a long way. Today, they are a popular alternative to glasses, providing wearers with clearer vision and more freedom of movement. As technology continues to evolve, the future of contact lenses looks brighter than ever.

Smart Contact Lenses

Smart contact lenses are one of the most exciting developments in contact lens technology. These lenses are designed to do more than just correct vision. They are equipped with sensors and miniature electronics that can provide wearers with a range of features and functions. For example, smart contact lenses could be used to monitor blood glucose levels in diabetic patients, or track eye pressure in glaucoma patients. They could also offer virtual or augmented reality experiences, transforming the way users see and interact with the world around them.

The potential applications for smart contact lenses are vast, and researchers are only just beginning to scratch the surface of what is possible. In the coming years, we can expect to see a range of new features and functions added to smart contact lenses, making them an even more valuable tool for healthcare and entertainment.

Biodegradable Contact Lenses

Contact lenses are a boon to those who need vision correction, but their environmental impact is a cause for concern. Disposable lenses that are not disposed of properly can contribute to plastic pollution in our oceans and landfills. That's why researchers are working to create biodegradable contact lenses that can break down naturally in wastewater treatment systems, reducing their environmental impact.

Biodegradable contact lenses are made from materials that can decompose in the presence of microorganisms naturally. They can also help to reduce the environmental impact of contact lens wear. It is hoped that biodegradable contact lenses will soon to be available and help to minimize the contribution of disposable contact lenses to plastic waste.

Continuous Advancements

The future of contact lenses is not just limited to smart lenses and biodegradable materials. With advancements in both materials and technology, contact lenses will continue to improve in comfort, convenience, and features. This means better vision correction, enhanced visual acuity, and improved overall eye health. Contact lenses will continue to play an essential role in the lives of millions of people worldwide, providing them with improved vision and enhanced quality of life.

As technology continues to evolve, we can expect to see new and exciting advancements in contact lenses. From smart contact lenses to biodegradable materials, and everything in between, contact lenses will continue to provide wearers with clearer vision, better comfort, and more freedom than ever before.
