PURPOSE/BACKGROUND: Many visual functions change with age. Hyperacuity vernier thresholds, however, seem to remain practically invariant with age.
We critically review reports on age-related changes in hyperacuity thresholds and present new data using two and three-point vernier hyperacuity thresholds.
It appears as though the vernier (two dot or two line) alignment hyperacuity thresholds are not sensitive to age.
Based on these studies we propose that hyperacuity (vernier) thresholds be used as a benchmark, or a gold standard for aging studies. This measurement can serve as a valuable control and reference for other clinical studies of aging.
目的/背景：许多视觉功能会随着年龄的增长而发生变化。然而，超敏锐度游标阈值似乎实际上不会随年龄而变化。
我们严格审查了关于超敏锐度阈值与年龄相关变化的报告，并使用两点和三点游标超敏锐度阈值呈现了新的数据。
似乎游标（两点或两线）对齐超敏锐度阈值对年龄不敏感。
基于这些研究，我们建议将超敏锐度（游标）阈值用作衰老研究的基准或金标准。这种测量可以作为其他衰老临床研究的有价值的对照和参考。
