The Benefits of Contact Lenses

Contact Lenses are thin, near-disposable lenses placed directly onto the cornea (the transparent, dome-shaped part of the eye) surface. Contact lenses are the most popular ocular prosthetics used by more than 150 million individuals worldwide, and they are worn as corrective ophthalmic devices for aesthetic or corrective reasons. For anyone considering wearing contact lenses, it is a good idea to understand how they work and what to expect when you first put them in. With this information, you can make an informed decision about whether contact lenses are right for you.

Contact lens

The primary function of contact lenses is to provide stable vision with improved vision accuracy and comfort. The primary components in contact lenses are a contact lens tube that is filled with a prescribed solution, a bifocal plastic lens designed to accommodate a particular prescription, and the appropriate medication. The solution and medication are prescribed according to the specific needs of the individual patient. There are several different types of prescriptions available for vision correction, including but not limited to: rigid gas permeable contact lenses (also known as gas permeable contact lenses, GPR, or progressive multifocal contact lenses), and gas permeable non-rigid gas permeable contact lenses (NPL, or non-rigid gas permeable contact lenses). There are even some specialty lenses such as silicone hydrogel contact lenses, polycarbonate lenses, and toric contact lenses.

For those suffering from vision problems due to refractive errors, nearsightedness or farsightedness, there are options available for these conditions. In addition to contact lenses for the correction of nearsightedness and farsightedness, there are options for improving your vision naturally through the use of Bifocals. Some of these include the use of contact lenses or glasses for short-term vision problems and the use of soft contact lenses or glasses during extended stays at the office or hospital. For many people, wearing glasses is simply inconvenient, while other people have vision problems that make wearing glasses impossible.


For those suffering from serious refractive errors, daily contact lens wear may be necessary. This type of situation requires the use of disposable multifocal contacts or Bifocal Contact Lenses, which are made up of two separate pieces – a top layer of polycarbonate that is rigid and a soft cover over a hard core called an image contributor. Both of these components need to be cleaned regularly. If your eyes are kept dry and clean at all times, you will not only be able to avoid dry eyes and smoky, poor vision, but also the frequent cleaning and replacement of these two components.

The use of contact lenses also makes it much easier to avoid common eye diseases and infections. Since you will not be touching your eye with your hands or using the same lenses that you will use for a period of time, you will be much less susceptible to bacteria or viruses such as bacteria that cause conjunctivitis or chlamydia. In addition, your eye doctor will be able to monitor the health of your eyes without you having to do so yourself. Should problems occur, the eye doctor will be able to prescribe the appropriate medication and even refer you to a specialist for further care and treatment.


Another advantage to contact lenses is the fact that they will eliminate the need for eyeglasses. If you wear glasses, it can often be difficult to find a suitable prescription for an affordable pair. Furthermore, if you have ever suffered from dry eyes or corneal ulcers, you know that wearing glasses can make these ailments worse. On the other hand, if you use gas permeable lenses, you will be able to see clearly without the use of prisms, lenses or spectacles. However, you should not wear these types of lenses for a great number of hours each day, but if you wear them occasionally for a short amount of time, like for an extra long drive or during sleep, you may find that they are comfortable and do not interfere with your vision.
