Here's a simple guide on how to read your prescription:

  1. OD and OS: These abbreviations stand for "oculus dexter" (right eye) and "oculus sinister" (left eye). The information for each eye will be listed separately.
  2. Sphere (SPH): This indicates the lens power needed to correct nearsightedness (-) or farsightedness (+). A minus sign indicates nearsightedness, and a plus sign indicates farsightedness.
  3. Cylinder (CYL): This represents the degree of astigmatism correction needed, if any.
  4. Axis: This number defines the orientation of the cylindrical power for astigmatism correction.
  5. Add: This is an additional correction for presbyopia or reading glasses. It's the added magnifying power applied to the bottom part of multifocal lenses.
  6. Pupillary Distance (PD): This is the distance between the centers of your pupils, crucial for accurate lens placement.

Example:
OD: -1.25 -0.50 x 180
OS: -1.50 -0.75 x 175
Add: +2.00
PD: 64 (Right) / 62 (Left)

In this example:

  • The right eye has a sphere power of -1.25, a cylinder power of -0.50 at an axis of 180 degrees.
  • The left eye has a sphere power of -1.50, a cylinder power of -0.75 at an axis of 175 degrees.
  • An additional power of +2.00 is added for reading.
  • The pupillary distance is 64 for the right eye and 62 for the left eye.
