In a placebo-controlled experiment comprising 22 healthy men (mean age 27.4 years), we investigated the influence of three breath levels of blood alcohol (BrAC; 0.0%, 0.05% and 0.1%) upon distant visual acuity, stereoacuity, contrast sensitivity, accommodation, resting focus of accommodation and binocular vision. Positive (PRA) and negative accommodation (NRA) and resting focus of accommodation showed no significant changes with increasing BrAC. Compared to the placebo condition, visual acuity and refraction were only significantly affected at a breath alcohol level of 0.1%. Contrast sensitivity, stereoacuity and binocular vision were affected both at BrAC 0.05% and BrAC 0.1%. Only the higher spatial frequencies of contrast sensitivity were affected.
在一项包含22名健康男性（平均年龄27.4岁）的安慰剂对照实验中，我们研究了三种呼气酒精浓度（BrAC；0.0%、0.05%和0.1%）对远视力、立体视锐度、对比敏感度、调节功能、调节静止焦点和双眼视觉的影响。正性调节幅度（PRA）、负性调节幅度（NRA）和调节静止焦点并未随BrAC升高而出现显著变化。与安慰剂状态相比，仅在呼气酒精浓度为0.1%时，视力和屈光才受到显著影响。对比敏感度、立体视锐度和双眼视觉在BrAC为0.05%和0.1%时均受到影响。仅对比敏感度的较高空间频率受到影响。
