Yes, it is possible to have a negative optical density (OD) in one eye (OD) and a positive optical density in the other eye (OS) when measuring certain parameters, such as in the context of vision correction or disease assessment. This can occur in cases of asymmetrical refractive errors or differing conditions affecting each eye. The terms "negative" and "positive" in this context typically refer to the refractive power of lenses needed for correction, where negative indicates myopia (nearsightedness) and positive indicates hyperopia (farsightedness).

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.
