OD means right eye, the D is the abbreviation for "dextro" which is the Latin word for "right".
Axis means the angle of the cylinder shape in the lens to correct for astigmatism.
Your prescription indicates the following for each eye: "OD" refers to your right eye, and "OS" refers to your left eye. The "Sphere" values (1.00) indicate the degree of nearsightedness or farsightedness, with positive numbers for farsightedness and negative for nearsightedness. The "Cylinder" values (-1.00 for OD and -1.75 for OS) indicate astigmatism, while the "Axis" values (180 for OD and 176 for OS) specify the orientation of the astigmatism correction in degrees.
That's the prescription for a corrective lens for your right eye, which is slightly far-sighted and slightly astigmatic.
"od" on a prescription for eye drops mean "right eye"--as in apply the drops to the right eye. "os" means "left eye".
If your optical prescription indicates an OD (right eye) axis of 075, it means that the cylindrical correction for astigmatism in your right eye is oriented at an angle of 75 degrees. The axis measurement specifies the direction in which the cylindrical lens power is applied to correct the irregular shape of the cornea or lens. This information is essential for ensuring proper alignment of corrective lenses to improve vision.
The prescription indicates the refractive error for each eye. "OD" refers to the right eye and "OS" refers to the left eye. The values show that the right eye has no spherical correction (0.00) but requires a cylindrical correction of -1.25 with an axis of 70 degrees, indicating astigmatism. The left eye also has no spherical correction but requires a cylindrical correction of -0.75 with an axis of 100 degrees, suggesting a lesser degree of astigmatism.
"OD" in an eye prescription stands for "oculus dexter," which means right eye in Latin. It indicates the specific correction needed for the right eye. The prescription for the left eye is labeled as "OS" for "oculus sinister." Understanding these labels helps ensure the correct lenses are prescribed and fitted for each eye, leading to accurate vision correction.
OD -1.50 1.25x180 refers to a prescription for corrective lenses for the right eye (OD stands for "oculus dexter"). The -1.50 indicates a nearsightedness (myopia) correction of -1.50 diopters, while the 1.25 represents the astigmatism correction in diopters. The "x180" specifies the axis of the astigmatism correction, measured in degrees, with 180 degrees indicating the orientation of the cylindrical lens needed to correct the astigmatism.
Your right eye RX (OD) is very weak. Your left eye RX (OS) is rather mild. -US Navy Optician
When "OD" follows a doctor's name, it typically stands for "Doctor of Optometry." This designation indicates that the individual has completed the necessary education and training to provide eye care services, including vision testing, diagnosis of eye diseases, and the prescription of corrective lenses. Optometrists play a crucial role in maintaining eye health and vision.
A prescription would be needed to determined the 'power' of each eye if you're ordering contacts. If you're unsure and/to unable to get an eye exam to determine your prescription, to be on the safe side order +0.00 OS and +0.00 OD.
The vision prescription OD 1.25 SPH (right eye) and OS 0.75-0.50x015 (left eye) indicates that the right eye requires a spherical correction of +1.25 diopters, while the left eye has a spherical correction of +0.75 diopters and a cylindrical correction of -0.50 diopters at an axis of 15 degrees. This means the left eye has some degree of astigmatism, which affects how light is focused on the retina. The overall vision correction aims to provide clear and balanced sight in both eyes.
OD can mean many things including once daily, right eye, overdose, or Optometry Doctor, depending on the context.
