Can you have a negative OD and a positive OS? - Answers

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).
