Understanding Your Eyeglass Prescription: A Guide by OptoDoc
Have you ever looked at your eyeglass prescription and wondered what all those numbers and terms mean? You’re not alone. Eyeglass prescriptions can seem confusing, but understanding them is crucial for ensuring you get the right lenses for your vision needs. At OptoDoc, we believe in empowering our patients with knowledge. Here’s a comprehensive guide to help you decode your eyeglass prescription.
The Basics of an Eyeglass Prescription
Your eyeglass prescription contains specific details about the lenses needed to correct your vision. Here’s a breakdown of the most common terms and numbers you’ll find:
1. OD and OS
OD (Oculus Dexter) refers to your right eye, and OS (Oculus Sinister) refers to your left eye. Sometimes, you’ll also see OU (Oculus Uterque), which refers to both eyes.
2. SPH (Sphere)
The SPH value indicates the lens power required to correct nearsightedness (myopia) or farsightedness (hyperopia). A negative number indicates myopia, while a positive number indicates hyperopia. The number is measured in diopters (D).
3. CYL (Cylinder)
The CYL value indicates the lens power needed to correct astigmatism. If there’s no astigmatism, this section may be blank. Like SPH, CYL is also measured in diopters and can be either positive or negative.
4. Axis
The axis value specifies the orientation of astigmatism correction. It’s a number between 1 and 180 degrees that indicates the direction in which the cylindrical power should be applied to correct astigmatism.
5. ADD
The ADD value is used for bifocal or progressive lenses and indicates the additional magnifying power needed for reading or close-up work. This value is always positive and measured in diopters.
6. Prism
The prism value is used to correct eye alignment issues. It’s measured in prism diopters and indicates the amount of prismatic power needed. The direction is specified as base up, base down, base in, or base out.
