When Were Soft Contacts Invented?

Soft contact lenses are now considered a popular choice for vision correction, but the road to their invention and production was not an easy one.

History of Contact Lenses

The idea of contact lenses dates back to Leonardo da Vinci in 1508. He sketched a concept of the eye's cornea being covered by a clear lens putting forward the idea of aesthetics and vision correction. However, it took more than 300 years of development and experimentation to get there.

Swiss physician Fick and Parisian optician Contact lens history started in the second half of the 1800s. In 1887 the first glass lens was made. Wearers placed it directly on the eye, and it was able to correct certain kinds of sight problems. Soon after, a plastic version was developed that increased comfort while still providing vision correction.

Development of Soft Contacts

By the 1960s, scientists had uncovered a new material that would change the contact lens industry forever: hydrogel. Czech chemist Otto Wichterle discovered that it was possible to mold hydrogel to create a flexible and water-absorbing lens. After years of experimentation, he succeeded in creating the first soft contacts in 1961.

Soft lenses of a new material allowed to be much more oxygenated than before, their edges could be soft so that they would not rub against the eye surface which promotes better comfort for extended periods of wearing. The soft contact lenses also helped to correct far more refractive errors. Despite the high cost of producing soft contacts, they became increasingly popular for use among consumers as soon as the technology allowed for mass production, and today they are considered the standard.

Advancements in Soft Contact Design

Over time, scientists and manufacturers continued to innovate, creating different materials such as silicone hydrogel lenses that allow more oxygen to the cornea and making them more comfortable for extended wear. There are also now different types of soft lenses to suit diverse eye conditions. Daily disposables provide unparalleled convenience for those with active lifestyles, and toric lenses are available for those with astigmatism. As a result of this innovation, wearing contact lenses considered more of an option for people today than previously.

Overall, the history of contact lenses has been one of continuous development and innovation. The introduction of soft contacts brought such a dramatic change to the industry that even now, over 50 years later, they continue to be the go-to for almost all contact lens wearers.

This material creates a lens that conforms to the shape of the eye, making it more comfortable to wear for extended periods of time. Unlike their rigid counterparts, soft contacts don’t cause discomfort, irritation or redness, and they allow for better oxygen flow to the cornea, promoting ocular health. This means that soft contact lenses can be worn for longer without causing any undue discomfort to the wearer.

Better Vision Correction

Soft contact lenses have the ability to correct a variety of vision problems. They can correct nearsightedness, farsightedness, astigmatism, and presbyopia, which is an age-related condition that causes difficulty in seeing objects up close. Soft contacts are the best option for people with high degrees of astigmatism or irregularly shaped corneas. This is because they offer a greater degree of flexibility and can conform to the shape of the eye more easily.

Convenient and Versatile

Soft contact lenses are more convenient than glasses, and they are ideal for people who are active or involved in sports. They allow for greater freedom of movement and do not get in the way during physical activity. Soft contacts come in a variety of types, including daily disposables, extended wear, and colored lenses for cosmetic purposes. Daily disposables are ideal for people who don’t want to deal with the hassle of cleaning and maintenance. Extended wear lenses can be worn continuously for a period of days or weeks, depending on the type of lens, before they need to be replaced. Colored lenses are great for people who want to change the color of their eyes for cosmetic reasons. These versatile features make soft contacts an excellent option for those with varying lifestyles and preferences.

In conclusion, soft contact lenses have revolutionized the field of vision correction. They provide greater comfort, better vision correction, and more convenience and versatility than traditional glasses. Soft contacts were invented in the 1960s and have undergone many advancements since then. These advancements have made them a popular and reliable choice for millions of people around the world. Thanks to continued innovation, the future of soft contacts looks brighter than ever before.

When Were Soft Contacts Invented?

Have you ever wondered when soft contacts were invented? To answer this question, we need to look back in history and explore the evolution of contact lenses.

How Contact Lenses Evolved

The idea of using lenses to help people see better dates back to the 1500s. In those days, people would hold pieces of glass against their eyes to improve their vision. However, it wasn't until the late 1800s that the first contact lens was created. These lenses were made of glass, and they were large and uncomfortable. They could only be worn for a few hours at a time, and they frequently popped out of the eye.

It wasn't until the 1930s that the first plastic contact lenses were invented. These lenses were smaller and more comfortable than their glass predecessors. However, they were still hard and inflexible, which could cause discomfort and vision problems. It wasn't until the 1960s that soft contact lenses were introduced, revolutionizing the world of vision correction.

How Soft Contact Lenses Work

Fitting Process

Soft contact lenses are fitted to each individual's unique eye shape and prescription. This process ensures that the lenses will be comfortable and provide optimal vision correction. The fitting process involves evaluating the curvature of the eye, measuring the size of the pupil, and considering any pre-existing conditions that might affect the fit of the contacts. A professional optometrist or ophthalmologist is best equipped to guide you through the process of finding the right soft contacts for your eyes.

Material and Design

Soft contact lenses are made of hydrophilic materials such as silicone hydrogel, which allows for water and oxygen to pass through the lens. This material is soft and pliable, which makes the lenses more comfortable to wear for long periods of time. The design of the lens also allows for proper tear flow to prevent dryness and discomfort. This means that soft contacts are less likely to cause eye irritation and infection compared to their hard counterparts.

Care and Maintenance

Proper care and maintenance of soft contact lenses are important for maintaining healthy eyes and optimal vision correction. This involves daily cleaning using contact lens solution, washing your hands before and after inserting or removing the lenses, replacing the lenses as recommended by your optometrist or ophthalmologist, and avoiding wearing the contacts for longer than the recommended duration. This will reduce the risk of developing eye infections, which can lead to more serious vision problems.

In conclusion, soft contact lenses were invented in the 1960s, and they have come a long way since their introduction. They provide a comfortable and effective way to correct vision problems, and they are an excellent alternative to traditional eyeglasses. By understanding how soft contacts work and taking proper care of them, you can enjoy years of clear vision and healthy eyes.
