lens prescription

A lens prescription specifies the corrective power needed to correct your vision, measured in diopters (D). It includes numbers for each eye, indicating whether you are farsighted or nearsighted, and the strength of the correction needed. A negative number (e.g., -3.00) means you are nearsighted and need lenses to help see distant objects clearly. A positive number (e.g., +2.00) means you are farsighted and need lenses for close-up tasks. Prescriptions may also include measurements for astigmatism and the position of the lens, ensuring optimal correction for your individual vision needs.
