Abstract

A potential concern in some studies of dark focus accommodation is the role of pupil size (and related spherical aberration) in laser optometer measurements. Dark focus measurements were obtained for 25 young adult subjects while they viewed the laser speckle pattern through artificial pupils of 3, 4, 5, 6, 7 and 8 mm diameter. Analysis showed no significant effect of pupil size on dark focus. It would appear that pupil size variations should not be a source of concern in laser optometer dark focus assessment.

摘要

在一些关于暗焦点调节的研究中，一个潜在的问题是瞳孔大小（以及相关的球差）在激光验光仪测量中的作用。对25名年轻成年受试者进行了暗焦点测量，他们通过直径为3、4、5、6、7和8毫米的人工瞳孔观察激光散斑图案。分析表明，瞳孔大小对暗焦点没有显著影响。看来，在激光验光仪暗焦点评估中，瞳孔大小的变化不应成为一个令人担忧的问题。
