Spectacle lenses with arrays of lenslets have gained popularity in myopia control due to their high efficacy, low impact on visual performance, and non-invasiveness. One of the questions regarding their impact on visual performance that still remain is that: do the lenslets impact visual field sensitivity? The current study aims to investigate the impact of wearing spectacle lenses with highly aspherical lenslets (HAL) on the visual field sensitivity.
An automated static perimetry test (Goldman perimeter target III) was employed to measure the detection sensitivity in the visual field. Targets were white light dots of various luminance levels and size 0.43°, randomly appearing at 76 locations within 30° eccentricity. Twenty-one adult subjects (age 23-61, spherical equivalent refractive error (SER) -8.75 D to +0.88 D) participated in the study. Sensitivities through two lenses, HAL and a single vision lens (SVL) as the control condition, were measured in random order.
The mean sensitivity differences between HAL and SVL across the 76 tested locations ranged between -1.14 decibels (dB) and 1.28 dB. Only one location at 30° in the temporal visual field reached statistical significance ( < 0.00065) whereby the sensitivity increased by 1.1 dB with HAL. No significant correlation was found between the difference in sensitivity and age or SER. Such a difference is unlikely to be clinically relevant.
Compared to the SVL, the HAL did not change detection sensitivity to static targets in the whole visual field within 30° eccentricity.
带有微透镜阵列的眼镜片因其高效、对视觉性能影响小以及非侵入性等特点，在近视控制方面越来越受欢迎。关于其对视觉性能影响仍存在的一个问题是：微透镜会影响视野敏感度吗？当前研究旨在调查佩戴具有高非球面微透镜（HAL）的眼镜片对视野敏感度的影响。
采用自动静态视野计测试（Goldman周边视野计III型）来测量视野中的检测敏感度。目标是不同亮度水平、大小为0.43°的白色光点，随机出现在30°偏心度范围内的76个位置。21名成年受试者（年龄23 - 61岁，等效球镜屈光不正（SER）为 - 8.75 D至 + 0.88 D）参与了该研究。以随机顺序测量通过两种镜片（HAL和作为对照条件的单焦点镜片（SVL））的敏感度。
在76个测试位置上，HAL和SVL之间的平均敏感度差异在 - 1.14分贝（dB）至1.28 dB之间。仅颞侧视野30°处的一个位置达到统计学显著性（< 0.00065），使用HAL时敏感度增加了1.1 dB。敏感度差异与年龄或SER之间未发现显著相关性。这样的差异在临床上不太可能具有相关性。
与SVL相比，HAL在30°偏心度范围内并未改变整个视野中对静态目标的检测敏感度。
