Contact Lens Facts Contact Lenses Vs. Eyeglasses And Where To Buy Contact Lenses- What To Consider When Purchasing

By: CJ Folkes

Contact lenses, also known as contacts come in both hard and soft options. Contacts usually serve the same purpose as conventional spectacles but are less cumbersome and practically invisible.
They are frequently composed of different types of polymers and contain some variant of silicone hydrogel. Hydrogel is water soluble. This property makes them flexible, similar to the human tissue.
In the past, hard contact lenses consisted of a polymer known as PMMA, or Polymethyl methacrylate. They have since been replaced by rigid gas-permeable (RGP) contact lenses. Today many contact lenses are made of hydrophilic, or 'water absorbing' materials. This allows oxygen to reach the cornea, and make the lens comfortable to use.
It has been estimated that 125 million people use contacts worldwide. Approximately 35 million people in the United States wear contact lenses. The varieties of contacts purchased vary considerably between countries. Germany, Netherlands and Japan purchase select Disposable Lenses about eighty percent of the time and about 95% of the time in Scandinavia.">http://www.shoplens.com/result.asp?SID=B0FCF5F1-7555-4937-B15B-FB868B77A7D1"> Disposable Lenses about eighty percent of the time and about 95% of the time in Scandinavia.
In addition to the practicality, many people wear contact lenses because they think that they appear less attractive when wearing eye glasses. Contacts are easier to replace than glasses and don't steam up. Glasses can be dangerous when used while doing vigorous activity and eye glasses don't have the wide field of vision that contact lenses offer. Some doctors instruct their patients to use contacts for particular vision issue that can't be addressed with glasses, such as keratoconus and aniseikonia. Patients with these problems often have better vision when wearing contacts.
Many patients with imperfect vision begin wearing contacts when they reach puberty are about 10 years old. This is a time of life when appearance is a serious concern. This is an issue for teenagers that are active in sports and programs in which they perform.
Contacts use continues throughout a patient's life, particularly now that there are more uses for contacts that apply to both the patients' medical and personal needs, such as Colored Contacts and stigmatisms.">http://www.shoplens.com/Colored_Contact_Lenses.asp">Colored Contacts and stigmatisms.
There are numerous options for buying contacts. Purchasing contacts online can be easy and less expensive than buying from a doctors' office. The contacts are delivered to your door. It is imperative that you purchase from a reputable company that will verify your prescription with your doctor. If this were not taken care of you may get the wrong prescription. They make sure you get what you need.
Shoplens.com is a reputable company with a vast selection, including colored contacts, PureVision, Softlens 66 Toric, Acuvue Oasys, PureVision Multi Focal, Pure Vision Toric, Acuvue 2, Acuvue Advance with Hydroclear, and numerous other popular and hard to find products.
When you order on the Internet the turn around time is superior. You can elect to pay more and get the contacts delivered sooner, but the delivery time is already quick. When you compare the prices of Shoplens.com to 1 800 Contacts you will see that shoplens.com actually passes the savings on to you.
I particularly like the reorder program. It allows you to refill an order with the same prescription until the prescription expires. It is stress free, when you know that most contact lens orders ship directly from the manufacturer.
