Basic Elements Of A Contact Lens Fitting

Submitted by: Adrianna Notton

One thing about wearing glasses that is much easier than wearing contacts is the fitting process. Since the contact lens sits directly on your cornea, it s very important that the correct measurements are taken and that it fits properly. If the fit of contacts is even a little off, you may experience problems while you wear them. Clear vision and comfort are the two most important elements of wearing contact lenses, and both are affected by the fit of the lenses in your eyes. Whether you seek out cheap contacts or the most expensive ones in the store, the correct fit is crucial. All contact lens fitting consist of a few basic elements.

Before the fitting for contacts even begins your eye doctor will test your eyes to determine the strength of corrective lens you need. Then, they will help you decide on the right type of contact lenses for you. They will ask you several lifestyle questions and your preferences regarding the wearing and hygiene schedules. After the testing is done and decision about which type of contacts to wear is complete, you ll need corneal measurements taken. Contact lenses are not a one-size-fits all kind of product, and the size and curvature of the lens must be correct. The doctor will likely use a device called a keratometer to measure your cornea during the fitting. This takes pictures of your eye to determine the curvature and size of contacts you ll need for a proper fit.

The doctor will also measure the size of your pupils to help ensure properly fitting contact lenses. The diameter of your iris is also recorded and in some cases a tear film evaluation is taken. This helps to determine if you have dry eyes, and the result may cause you to rethink the choice for contacts. If you have a problem with dry eyes, wearing contact lenses can be quite uncomfortable as the day rolls along. At the least, you will be given eye drops and instructions on how to keep your eyes and contacts moist.

Your eye doctor may also use a biomicroscope to get a highly magnified view of your cornea, so they can watch how a trial contact lens fits in your eye. If the doctor chooses to go with trial contacts, you ll probably have to wear them for at least 15 minutes to get a true sense of how they fit. They can then give your eyes a detailed examination and determine if the contact lenses fit properly or not. It s common for contact lens fittings to take at least two office visits, to ensure the right size and style has been selected. Once the fit is good, you ll get your prescription and you can go get it filled. Cheap contacts are usually available through specials or promotions at many optical stores. Whether you find cheap contacts or not, make sure you give your prescription details to the retailer preparing them for you, and double check at the end that it s the right one.
