Prescription confusion

Hi, I'm sure this is common newby question, but I'm a bit confused.

I just had my eyes examined by a different optometrist than for my exam 18 months ago. The Dr. told me that my prescription had not changed much so I'm still debating whether to get new lenses yet or not.

My question is: In comparing the the two prescriptions, they appear to be using different units. For example, the first doctor uses decimals to express Sphere, Cylinder and Add (-0.25, -1.5, +2.50). The second doctor uses whole numbers (Sphere 101, Cylinder -175, Add +295).

Are these two different ways of expressing the same thing?

Thanks,

It's the same thing. Doc #2 just isn't adding the decimal point.

 

When comparing the two prescriptions, it's evident that they utilize different units of measurement. The first doctor employs decimals to express the values for Sphere, Cylinder, and Add (-0.25, -1.5, +2.50). In contrast, the second doctor uses whole numbers (Sphere 101, Cylinder -175, Add +295). The variation in units can potentially lead to confusion or the need for conversion when interpreting and comparing the prescriptions.

 

These two prescriptions are similar, they have just used different units of measurement.
