Corneal touch threshold (CTT) was measured in 205 healthy people of different ages. It was found that CTT increased gradually throughout life, although more significantly after the fifth decade of life. The results are found to be in good accord with those of Boberg-Ans, thus refuting an earlier report asserting that corneal sensitivity (threshold-1) increased up to the fifth decade and declined thereafter,
对205名不同年龄的健康人进行了角膜触觉阈值（CTT）测量。结果发现，CTT在一生中逐渐升高，尽管在50岁以后升高更为显著。研究结果与博贝格 - 安斯的研究结果高度一致，从而反驳了早期的一份报告，该报告称角膜敏感度（阈值倒数）在50岁之前上升，之后下降。
