Price and history of contact lenses

The price of contact lenses involves several factors. Cost to manufacturer is only one of them. Others include packaging, distribution and promotion and so on. In addition, retail or discount merchant also puts markup. Contact lenses are now available in various sources, including eye doctors, chain-store optometrists, malls, online stores etc.

Current prices of contact lenses are relatively lower than that in the past. One reason should be given to the advances in manufacturing methods and materials. Furthermore, customers also benefit from the federal law named Fairness To Contact Lens Consumers. Went into effect on February 4th 2004, this law enables individuals to get a copy of their prescriptions from the eye doctor after being examined.

With a valid prescription, they are free to buy contact lenses from any sources. However, customers are encouraged to have their lenses fitted by a local professional. Local fitting and follow-up examination can ensure a best practice.

Contact lenses have undergone a long history. Made in the late 19th century, the first usable contact lenses had a design that covered the entire visible surface. These early contact lenses were affordable only by actors, very vain people and individuals with environmental demands. Using glass blowers, these lenses were quite uncomfortable.

Polymethyl methacrylate lenses occurred in the 1930s. First made on lathes, these rigid lenses were eventually manufactured automatically, which considerably brought down the price. This advancement also made mass production of scleral lenses possible.

The development of manufacturing technologies and creation of new lens materials have greatly brought contact lenses to the public. A first step was that rigid lenses were perforated by tiny holes in order to allow more oxygen to reach the cornea. Later, rigid gas permeable lenses were created. Publishes by Czech chemists Otto Wichterle and Drahoslav Lim in 1959, hydrophilic gels for biological use pushed the lens development to a much higher place. After a short time, soft lenses were introduced in Europe and then in North America after 10 ten years.

Several factors have helped bring down the price of contact lenses. Technological advancements have significantly improved oxygen permeability and moisture of lenses. In addition, competition among big lens brands as well as online discounters also helps customers get low price contacts.
