Which best describes the mire position when the cornea is properly centered and applanated?

Explanation:
The mire position is best described by the inner edges of the semicircular mires touching each other. This indicates proper centering and applanation of the cornea, showing that the correct amount of flattening has occurred for the standard measurement. If the inner edges don’t touch (there’s a gap) or if the semicircles overlap, it means the alignment or pressure is off, leading to incorrect IOP estimation.
