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.
For several reasons, close to 125 million people are now wearing contacts. Glasses do not cover the entire peripheral vision. A pair of contacts can solve this problem and is invisible to the eye. Unlike glasses, rain, steam, or heat does not affect them. Glasses will sometimes steam up or get wet so they are not usable. Sometimes these are required because glasses cannot always fix certain eye conditions.
Initially, glass was used in their manufacture. The negative feature of these glasses was that they caused irritation in the eyes could not be worn for lengthy duration. Another important step was the invention of hard lenses by the US ophthalmologist William Feinbloom, developed from a material called PMMA, also known as Perspex or Plexiglas. Although an improvement from the earlier invention, this was not ideal in the sense that it did not allow oxygen to reach the cornea of the eye causing some other problems.
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.
These lenses are sold under prescription after examination of the eyes. Prescriptions for the old pair of glasses won't be sufficient. As eye conditions vary, it will be looking for trouble buying visual aids without the specific recommendation of an optometrist.
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.
When looking online, there are so many options to choose from including brands, designs, or colors. Just remember that the online products do not mean lower quality. They can be discounted from buying in large quantities at cheaper rates.
If the supplier's contact address and credentials are not beyond doubt, it is better to avoid such people. The online world can at times be dangerous, so be on guard. Also consider independent opinions before ordering discount designer contact lenses online. Read on the net what others have to say about the supplier you may be considering.
