Decode Your Eye Prescription: A Simple Guide

Decoding your eye prescription empowers you to select appropriate lenses and prevent ordering mistakes. This precise record ensures light focuses correctly on your retina, clarifying blurry vision. Identifying OD/OS for right/left eyes and SPH for nearsightedness or farsightedness is fundamental to understanding your visual needs. Astigmatism is indicated by Cylinder and Axis values, while ADD values assist with close-up tasks, often increasing with age.

Prescriptions are not permanent and typically expire within one to two years for adults, and even sooner for children due to rapid vision changes. This renewal period also serves as a crucial opportunity for eye doctors to screen for silent eye diseases. It's important to note that a prescription for glasses cannot be used for contact lenses, as contacts require specific fittings and parameters due to their direct placement on the eye.
