Multiple-pinhole glasses are currently sold in many countries with unproven and exaggerated advertisements, however, its objective and subjective effects have not been investigated. Therefore, we quantified the visual functional changes caused by multiple pinhole glasses with 125 pinholes in each glasses lens. Multiple pinhole glasses enlarged pupil diameter from 3.6 mm to 6.0 mm and improved uncorrected distance and near visual acuity, depth of focus, and accommodative amplitude. However, contrast sensitivity, stereopsis, and visual field (VF) parameters including mean deviation, pattern standard deviation, and visual field index deteriorated. In conclusions, pinhole glasses had positive effects from the pinhole effect; however, they had negative effects on visual quality. In spite of the increased luminance and preserved peripheral VF with multiple pinholes, particular attention is needed when wearing pinhole glasses while driving, playing, sport, or working with instruments.
