Buying Lenses- Discount Contact Lens Facts

Buying Contacts Online - Are there really Discount Contacts? Consider the facts.

Contact lenses, also known as contacts come in both hard and soft varieties. Contacts usually serve the same purpose as conventional eye glasses but are less cumbersome and almost invisible.

They are often composed of various types of polymers and contain some variant of silicone hydrogel. . This makes them flexible, similar to the human tissue.

Previously, hard contact lenses were made 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 They have since been replaced by rigid gas-permeable (RGP) contact lenses.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 more comfortable to use.

It has been estimated that 125 million people use contact lenses around the globe. About 35 million people in the United States wear contacts. The types of contact lenses people are buying vary tremendously between countries. Japan, Netherlands and Germany buy select disposable contact lenses about 80% of the time and about ninety-five percent of the time in Scandinavia.

In addition to the practicality, many people wear contacts 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 contacts offer. Some physicians prefer their patients to use contacts for specific vision issue that can’t be addressed with glasses, such as keratoconus and aniseikonia. Patients with these conditions tend to 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 looks is a serious concern. This is an issue for teenagers that are active in sports and programs in which they perform.

Contacts use is continued throughout a patient’s life, especially now that there are more uses for contacts that apply to both the patients’ medical and personal needs, such as color contacts and stigmatisms.

There are numerous options for purchasing contacts. Purchasing contacts online can be hassle free and less expensive than buying from a doctors’ office. The contacts are delivered to your home. It is essential that you buy from a reputable online store that will verify your prescription with your doctor. If this were not taken care of you may get the wrong prescription.

Information on Keratoconus

Keratoconus is a rare condition. Keratoconus is a condition of the eye meaning conical conea. The cornea is the major focussing surface of the eye. Keratoconus may occur in one eye only initially but most commonly affects both eyes with one eye being more severely affected than the other. Both males and females are equally affected. As the disease progresses, the cone becomes more pronounced, causing vision to become blurred and distorted. Keratoconus is sometimes an inherited problem that usually occurs in both eyes. The weakening of the corneal tissue that leads to keratoconus may be due to an imbalance of enzymes within the cornea. This imbalance makes the cornea more susceptible to oxidative damage from compounds called free radicals, causing it to weaken and bulge forward. Keratoconus may be associated with allergy or possibly have a genetic component. Keratoconus rarely appears in an individual until puberty or beyond. Keratoconus is not usually visible to the naked eye until the later stages of the disease. In severe cases, the cone shape is visible to an observer when the patient looks down while the upper lid is lifted. When looking down, the lower lid is no longer shaped like an arc, but bows outward around the pointed cornea. Risk factors Keratoconus comprise oxidative injure and weakening of the cornea include an inherited predisposition, explaining why keratoconus frequently affects more than one member of the similar family. Keratoconus is also related with overexposure to ultraviolet rays from the sun, excessive eye rubbing, a history of poorly fit contact lenses and chronic eye irritation. The primary treatment for patients with keratoconus is to fit rigid gas permeable (RGP) contact lenses. In about 10% to 20% of keratoconus patients the cornea may become extremely steep, thin and irregular or the vision cannot be improved sufficiently with contact lenses. Some people with keratoconus can’t endure a rigid contact lens, or they reach the point where contact lenses or additional therapies no longer provide acceptable vision. The cornea may then need to be replaced surgically with a corneal transplant or graft. A surgical treatment involving riboflavin and UV light has been proposed. With this treatment, the corneal epithelium is first removed, and the corneal stroma is subjected to riboflavin and exposed to UV light. Radial keratotomy is a refractive surgery procedure where the surgeon makes a spoke-like pattern of incisions into the cornea to modify its shape.
