Online shopping has extended to contact lenses at very affordable prices. Members of the population who have vision problems will be pleased to know that they can find good quality discount contact lenses online. These products may be of good quality as well.

It is interesting to note that Leonardo da Vinci sketched and described something very similar to these little discs. The first pairs were only made some three hundred years later. Otto Wuchterle, a Czech chemist and his assistant Drohoslav Lim are documented as the inventors of the soft contact lenses.

About 125 million people across the globe wear contact lenses. Their reasons for this vision aid vary. Some prefer to be without uncomfortable spectacles which do not provide the same all round vision. Rainy weather does not affect the effectiveness of contacts. They cannot fog up like glasses either. There are also cases where contacts are the only solution to specific vision and eye problems.

Glass was the first material used in the manufacture of these little discs. It was not possible for a person to wear them for long periods as they did irritate the eyeball. An American optometrist, William Feinbloom, introduced his so-called hard lens which was made from Perspex, scientifically known as PMMA. This was more comfortable, but still posed a problem in that the cornea was starved of oxygen. Lack of oxygen to the cornea can lead to complications.

The introduction of hydrogel in 1960 by Wuchtele and Lim was the answer to all the problems. Contact lenses became much safer and more comfortable for the eyes. The lens can be tinted with color for easier visibility. This can be useful for cosmetic reasons as well. People can choose to change the color of their eyes. The tint can also act as a UV filter to protect the eye from harmful rays of sunlight.

You need to visit an optometrist if you wish to change your glasses for a new set of lenses. The prescription for glasses is the same as the one for contacts. The optometrist will examine your eyes to ascertain whether contacts will be suitable.

As with any purchase, it pays to shop around for a good price. You will probably find that going online will offer the best value for money. You will pay shipping and insurance when you order online or over the telephone, but the total cost may still be less than what the optometrist may charge you.

Discount prices do not necessarily mean inferior quality. The supplier can offer you a discounted priced if he has ordered items in bulk. He is passing on his saving to you. You will be able to choose from a variety of brands, colors and designs.

Do your homework before you order. Ask the supplier questions and stay away from him if you find his responses unsatisfactory or non-existent. Research supplier credentials online. Seek independent opinions about different suppliers. Know who you are dealing with before you order. Buying discount contacts online offers many advantages. You can save time and still find good value for money to look and feel good.
