What are Prescription Contact Lenses?

Contact lenses today are used for a variety of reasons. They could change a person`s look and make the person look more mysterious and somewhat different. They have become a vital part of various movies (especially horror, mystic and sci-fi movies) as they add certain features to the characters they are used on. Contact lenses now exist in more than a few colors and patterns. Not to mention the various forms of contact lenses such as mesh and scleral contact lenses. Starting from the delicate and meticulous processes involved in the insertion and subsequent removal of contact lenses, to the maintenance and cleaning of these lenses, show that contacts need to be used carefully. Although contacts lenses serve (quite efficiently) in creating several effects in movies and as very fashionable cosmetic gadgets, they were not initially created or invented for these purposes. Instead, they were invented to serve more therapeutic and medical or clinical effects as corrective measures.
What exactly then are prescription lenses? In some countries (such as the U.S), you need a prescription to use contact lenses. This is usually the case regardless of the reason or motive behind using the lenses. But the prescription contact lenses we are referring to here are different. The term prescription contact lenses are used when referring to contact lenses that have been fitted to serve corrective functions. These prescription contact lenses are vital therapeutic and medical aids. They are used in correcting various forms of eye defects such as myopia, presbyopia, hypermetropia, etc. As a matter of fact, most conditions that require the use of glasses could be tackled using contact lenses.
These prescription contact lenses are much more preferable in comparison to regular glasses. This is because first and foremost, it is not in the way. Typical glasses need constant adjusting and removal (to clean face when sweating) when engaging in various activities. But prescription contact lenses serve the same function of aiding and improving sight without “getting in the way”.
While prescription glasses and prescription contact lenses might serve the same function, they are not interchangeable. Prescription contacts require more work and the individual would need to be tested for suitability to use of prescription contact lenses. There are numerous conditions that allow the use of contacts, but even more conditions that prohibit its use. Typically, the center thickness, diameter, power, and material are considered when choosing a suitable contact lens for an individual.

Another major benefit is that, if you are qualified for use of contacts, you can decide to choose whatever color you want. As long as the color is not conflicting with the treatment or correction process. So all the same, prescription contacts, regardless of the color need to be handled by an optometrist, an ophthalmologist or an optician. Prescription contacts allow one to continue the treatment while still appearing fashionable. You could put on your contacts and still decide to wear those glasses you have been “aching” to try on.
