Types of Contact Lenses

Contact lens, also known as contact lenses, are small, thin lenses usually placed directly on the cornea of the eyes. Contact lenses are prosthetic vision devices used by more than 150 million individuals around the globe, and they are often worn as a replacement for glasses or other optical devices. The cost of purchasing and using contact lenses are often far less than the cost of wearing glasses or contact lenses.

There are several different types of contact lenses that an individual may be interested in ordering. In addition to a variety of colors and styles, there are also various sizes available. The shape of a contact lens may vary depending on the shape and size of an individual’s eye, but most contact lenses are available in oval, round, full circle, or even basketball-type shapes. Some individuals choose to purchase colored contact lenses, while others choose to purchase a simple color such as gray, brown, or black.

 

The primary type of contact lens is the full-eye contact lens, which is most often ordered by ophthalmologists for their patients who wear contact lenses for therapeutic or decorative purposes. Some people, however, prefer to wear extended-wear lenses – these lenses are designed to be worn for a period of time beyond the usual time frame for wearing eyeglasses. Extended-wear contact lenses can be worn during sports events and outdoor activities, as well as during sleep periods at night. These lenses do not require the same meticulous cleaning measures as their shorter-term counterparts.

Purchasing Contact Lens

There are a variety of reasons why a person may choose to purchase contact lenses rather than glasses. Some individuals choose to wear contact lenses because they provide a more comfortable, safer, and clearer vision than glasses. Contacts also provide a higher level of comfort than traditional glasses because they do not have to be replaced after every wearing. Some individuals wear contact lenses because they are more comfortable and easier to wear than glasses. They also provide a degree of flexibility that glasses do not provide. Finally, contact lenses can be more affordable and easier to replace in comparison to glasses.

Before purchasing contact lenses, an individual should visit his or her eye doctor to get a professional opinion on his or her vision. Eye doctors can examine your eyes and discuss what your options are when it comes to contact lenses. You can visit an optometrist in your area to get an eye exam and discuss your vision and what options you have available to you. If you prefer to buy your own contact lens, you can visit an eye doctor and get instructions on how to properly insert and remove them.

About

Today’s contact lenses come in a variety of styles and types, including both rigid gas-permeable lenses and soft gas-permeable lenses. Fluid-permeable lenses provide a higher level of hydration than their rigid counterparts do. For people who need just a small amount of hydration for better vision, the soft type is a good option. Rigid gas-permeable lenses, which are used for vision conditions such as astigmatism and myopia, work by retaining water within the cornea. Once a person wears rigid gas-permeable lenses, a small amount of water leaks into the cornea, causing the cornea to become dry and blurry. In some cases, these conditioners are treated with a medical solution, but most often the problem is corrected by keeping water within the cornea and preventing it from leaking out.
