At Legacy Optical, we strive to meet all of your eye and vision care needs. After your comprehensive eye exam is completed, a glasses prescription is finalized. Contact lenses have many different parameters that need to be determined by your doctor in order to best correct your vision and provide a comfortable lens fit. This includes lens power, the shape of your cornea, lens replacement schedule, and presence of any ocular surface diseases. Therefore, your glasses prescription may be different from your contact lens prescription.
In order to select the type of lens that best fits your visual needs and lifestyle, your doctor will discuss a variety of contact lens options with you. Contact lens fitting exams or lens evaluations may be scheduled after this process has been completed. A contact lens exam is different from a comprehensive eye exam and has a separate fee structure that will depend on lens parameters and exam difficulty.
Prior to prescribing contact lenses, your doctor determines what level of vision correction you require. Refractive error (commonly known as nearsightedness, farsightedness, astigmatism, and presbyopia) is evaluated by measuring how the eyes focus when a series of different lenses are placed in front of them. The optometrist will get an automated estimate of these values using an autorefractor and will then fine-tune the prescription using a phoropter. Once these measurements are determined, this will allow your doctor to find the correct contact lens powers for your eyes.
After determining the level of refractive error, your doctor will discuss whether contact lenses might be an option for you and your lifestyle. If you suffer from certain conditions, such as dry eye, allergies, or other ocular surface diseases, glasses may be the most comfortable corrective lens solution. Contact lenses are available in either soft or rigid gas permeable form. Contact lenses need to be changed daily, weekly, bi-weekly, or monthly, depending on what type of lens you select. There are also options to help correct presbyopia, such as monovision or multifocals, which is comparable to a bifocal or progressive pair of glasses. Specialized contact lenses, such as hybrid lenses and scleral lenses, are also available for patients with special eye conditions such as keratoconus.
Advances in contact lens technology have created great options for cosmetic and prosthetic lenses. Custom contact lenses can be created to camouflage any color variation or irregularity and produce a natural eye color. Cosmetic lenses are also available to transform your eye color. Ask your doctor if you are interested in modifying or changing your eye color with contact lenses.
