Obtaining Contact Lenses, What, Why, How?
Contact lenses are an excellent choice for all those who have problems with their eyesight. First, these are practically invisible, provide excellent improvement and are easy to be used. Also, when compared to spectacles, these are much harder to get damaged, since you wear them close to your eyes and do not expose them to outer contact. For all these reasons, and many others, many people choose to use contact lenses. However, it is not just about choosing. Namely, before you are able to purchase these lenses, you need to have a prescription for them, meaning that you need to be examined beforehand. There is no other possible way of obtaining contact lenses, at least not in the US. There are reasons behind this state of affairs. If you want to find out which are these reasons, read on.
Such Is the Law
Before the year of 2004, people were able to buy contact lenses directly from their doctors or eye care practitioners. However, in order to give future contact lens users ability of choice, they were allowed to compare prices and buy the lenses that suit them most, wherever they want. However, this is only possible with a prescription, regardless if these are colored lenses or any other type. The seller is forbidden to sell you the lenses without receiving the prescription. Moreover, he or she is instructed to contact the practitioner and confirm that he or she issued the prescription in the first place. Only after all these steps have been covered, can a person get contact lenses.
Why Is This So?
Each pair of contact lenses is unique and made specification for the person wearing them. Therefore, the materials from which the lenses are made have to be adequate. The same goes for the shape, and all other qualities which make one contact lens different from the others. So, in order to avoid having your eyes hurt or permanently damaged due to their exposure to contact lenses which are not made for you, you are unable to buy just any pair. Rather, you need to buy those which were made for you and your purposes. It is as simple as that. Contact lenses are medical items, and as such, they are sold only with a prescription.
Finally, if you do have a prescription, it is best to buy your contact lenses before the papers expire. If your prescription is out of date, and they often have a maximum of one year before expiry, you will have to undergo the eye exam once again and get another prescription issued.
