A millimetre will be accurate enough.
An increase in the cylinder measurement of the eye, often noted in an eye prescription, indicates a rise in astigmatism. Astigmatism occurs when the cornea or lens has an irregular shape, causing blurred or distorted vision. An increase in this value suggests that the degree of curvature irregularity has worsened, potentially requiring corrective lenses or treatment to improve visual clarity. Regular eye examinations are important to monitor changes and maintain optimal eye health.
The resolution of the human eye is often described in terms of visual acuity rather than a specific measurement in millimeters. However, it is commonly estimated that the eye can resolve details as small as 1 arcminute, which translates to about 0.3 millimeters at a distance of 20 feet (6 meters). This means that the eye can distinguish between two points that are separated by this distance under optimal conditions.

"P1" on an eye prescription typically refers to a measurement for the pupillary distance of the left eye. This measurement helps ensure that the lenses in your glasses are correctly positioned to align with your eyes, providing you with clear and comfortable vision.
Aberrometry specifies the measurement of the imperfections in the optical system of the eye, It is measured in microns

If you are talking about a liquid measuring cup (or a breaker) you must get eye level with the cup and where the line of water (meniscus) meats the line on the cup you have the correct amount.
