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.
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.
What does it mean?
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.
If you mean: 'De donde es Vd (=usted)?': 'Where are you from?', the answer is: 'Soy de....' ('I am from....') If 'od' in the question is not 'Vd/usted', it could mean: Where is he/she//are you from? OR (doubtfully): Where is od from?
Doctor of Optometry
OD can mean many things including once daily, right eye, overdose, or Optometry Doctor, depending on the context.
If you mean 0.75 then it is 3/4 as a fraction in its simplest form
125 is more than 075, so 125 mg is more than 075 mg.
When you with respect to the x-axis then this is like saying with reference to the x-axis. You are using the x-axis as a guide.
The y-axis is the vertical axis on a graph.
