Sphere (SPH)
Cylinder (CYL)
Axis
Addition (ADD) for bifocals or progressive lenses
Pupillary distance (PD)
Lens type
Other specifications or notes

Understanding the details on an eyeglass prescription can help ensure that you get the correct lenses tailored to your vision needs.

Patient’s Name and Date of Birth: The patient’s name and date of birth identify who the prescription is for and verify personal information for the eyewear provider. Accurate details are essential for record-keeping in optical offices.
Prescription Date: The prescription date indicates when the eye exam was performed. This date is important to determine if the prescription is still valid, as eyeglass prescriptions often have an expiration date.
Prescription Expiration Date: The expiration date signifies how long the prescription is considered valid. Most prescriptions have a validity period ranging from one to two years, depending on state regulations and the patient’s conditions.
Sphere (SPH): The sphere measurement shows the lens power needed to correct nearsightedness or farsightedness. The SPH value measures in diopters (D). A minus sign (-) indicates nearsightedness, while a plus sign (+) indicates farsightedness.
Cylinder (CYL): The cylinder measurement indicates the lens power needed for astigmatism, a common vision condition caused by an irregularly shaped cornea. Like the SPH, the CYL value is also expressed in diopters, with a minus sign for correction.
Axis: The axis value measures the degree of astigmatism and indicates the alignment of the cylindrical power. This measurement ranges from 1 to 180 degrees and is essential for properly aligning the lenses.
Addition (ADD): The addition value is used for bifocal or progressive lenses. It denotes the additional magnifying power required for close-up tasks, typically needed by individuals over 40. The ADD value is added to the sphere for reading.
Pupillary Distance (PD): Pupillary distance is the distance between the centers of the pupils, measured in millimeters. This measurement ensures that the optical center of the lenses aligns with the patient’s pupils, which enhances visual clarity.
Lens Type: The lens type specifies any special requirements for the lenses, such as coatings (anti-reflective, scratch-resistant) or specific materials (polycarbonate, high-index). Selecting the appropriate lens type can improve the durability and comfort of glasses.
Other Specifications or Notes: Additional specifications or notes may include instructions on the type of frame, recommended lens styles, or special considerations for specific vision conditions. These notes guide the Optical Dispenser in fulfilling the prescription accurately.
