What must be included on a spectacle lens prescription?

A spectacle lens prescription must include essential information that ensures the proper manufacturing and dispensing of the lenses. The correct answer involves the dioptric power of the lens and the prescriber’s information, which are critical components of a prescription.

The dioptric power specifies the corrective strength needed for the lenses to address the patient's refractive errors, such as myopia or hyperopia. Without this information, it would be impossible to create lenses that meet the patient's visual needs.

Additionally, the prescriber’s information is crucial for accountability and follow-up care. This typically includes the optometrist or ophthalmologist's name, license number, and contact details, ensuring that the dispensing optician or laboratory has a clear and identifiable source for any questions or clarifications that may arise concerning the prescription.

While patient identification details and information like visual acuity can be important for record-keeping and are sometimes included, they are not mandated for the actual lens prescription. Likewise, details about lens brand or color choice, though potentially requested by patients, are not necessary components of the prescription itself, as they do not affect the lens's corrective function. Therefore, the combination of dioptric power and prescriber’s information is essential to ensure the correct fabrication and fitting of spectacle lenses
