Abstract

fetched live from OpenAlex

Prismatic imbalance produced in the reading area by an anisometropic spectacle correction can be offset by various methods. If a reading addition is present, one method is to provide differently shaped segments and allowing their optical centers to be separated vertically while the segment tops remain in horizontal alignment. Traditionally, to apply this method, the relative prismatic difference at the reading point is first determined by a thin lens application of Prentice's rule. This rule is then applied a second time to determine the placement of the segments that will offset the prismatic difference produced by the major lenses. However, the conventional application of Prentice's rule for determining the fusional demand in a particular area of the spectacle field often produces very large errors, which will affect the calculation of the placement of the segments. This article develops and demonstrates more accurate methods for applying the principle of compensating segments.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
