 If you wear prescription eyeglasses and are planning on purchasing a pair of glasses online at, you will need a prescription and the Pupillary Distance (PD). The Pupillary Distance is the distance between your pupils, which is usually measured in millimeters. Most eye doctors, whether they are an optometrist or ophthalmologist, do not write this number on your prescription. An eye doctor assumes you will visit an eyeglasses store where an optician will measure your pupillary distance once you decide upon a frame.  However, if you plan on ordering your eyeglasses online, you need to ask your optometrist to write pupillary distance number on your prescription.

You will essentially by pass the optician when you purchase your eyewear at Opticians are employed at a national optics retail chain stores, hospitals, eye care centers, retail stores, or may have his /her own small, private eye clinic business. Similar to a pharmacist, an optician fills a prescription written by an optometrist or ophthalmologist based on an eye exam.  The optician then provides custom corrective lenses that fit into the eyeglasses frame selected by the customer. In the United States this type of eye doctor may be certified by the American Board of Opticianry, although some states such as Oregon due not require licensing to make or dispense eyewear. Opticians use a variety of equipment to aid them in the fitting, adjusting, and dispensing of eyewear, contact lenses, low vision aids or ophthalmic prosthetics for partially sighted persons. 

Purchasing prescription eyewear at may require you to visit an optometrist, an eye and vision health care professional who is also referred to as an eye doctor.  They provide eye examinations, diagnoses, management and non-surgical treatment for not only eye diseases such as cataracts, glaucoma, retinal disorders, lid disorders, prescribing medication to treat eye diseases or infections such as conjunctivitis, but also vision disorders and vision correction. They will also write an eyeglass prescription, if the patient needs one. Make sure they include the Pupillary Distance of your eyes since you will need it for purchasing eyewear at An optometrist evaluates and treats vision conditions such as nearsightedness, farsightedness, astigmatism and presbyopia. Some optometrists perform laser, refractive or glaucoma surgeries as well as providing pre- and post-operative care. 

Ophthalmologists, on the other hand, are eye surgeons who are either a Doctor of Medicine (MD) or a Doctor of Osteopathic Medicine (DO). They can perform all the same tests as an optometrist and in addition, they are a fully qualified medical doctor and surgeon. Their practice is in the specialized field of medicine that specifically concerns health problems of visual pathways that need surgical intervention. Typical operations performed by ophthalmologists deal mainly with the eye, and eyelids. Depending on the ophthalmologist’s specialty, it may also extend to include the brain and areas surrounding the eye such as the lacrimal system, which includes the orbital structures for tear production and drainage.
