提出滤光镜能提高视功能是在70多年以前,但直到最近一段时间才引起人们的重视。多数研究报告显示滤光镜能提高正常人和某些眼病患者的视功能,但也有些结论相反的报告。本文复习分析了有关文献,认为滤光镜能提高正常人和某些眼病患者的视功能(如对比敏感度),并认为今后应重点加强滤光镜如何影响低视力患者视功能的研究,以及影响滤光镜效果的因素。 It was proposed more than 70 years ago that filters could improve visual function, but it was not until recently that people paid attention to them. Most studies have shown that filters can improve the visual function of normal subjects and some patients with ophthalmic diseases, but there are some reports of the opposite. This review and analysis of the literature, the filter that can improve the visual function of normal subjects and some patients with ophthalmology (such as contrast sensitivity), and that the future should focus on how to strengthen the filter function of visual acuity in patients with low vision, and Factors that affect the filter effect.
