Contact lenses are one of the leading methods of vision correction—a close second to the eyeglasses, which have been in use for the last few centuries. Contact lenses, while originally conceived by the Italian Renaissance man Leonardo da Vinci, are a more recent development. Until the last few decades, contact lenses were not as popular because they were not very comfortable to wear.
Prescription contact lenses are the most popular kind of contact lenses in the market. These tiny, concave bits of polymer are designed to directly address vision problems such as myopia or nearsightedness, hyperopia or farsightedness, astigmatism (or a particular defect in the curvature of the cornea) and presbyopia (an eye condition associated with aging). As the name implies, prescription contact lenses are prescribed to patients by a qualified eye doctor—who will include in the prescription not only the power the patient requires, but also the size of the patient’s eyes.
Prescription contact lenses are often clear, which means that they are transparent and not colored to facilitate better and clearer vision. However, there are also prescription contact lenses for people who want a different eye color and for those who want to enhance the color of their eyes. Also, prescription contact lenses come in different powers and sizes, which assure patients with vision correction needs that they will find the pair that best fit their needs and eye size.
Prescription contact lenses will require meticulous maintenance in order to be kept clean and bacteria-free. Regular disinfecting with a contact lens solution will be very important in the care routine, as well as storing the prescription contact lenses in a solution that will soften the lenses for daily wear. Also, it is important for prescription contact lenses to be disposed on or before the expiration date indicated by the manufacturer.
