The effect of blue-light-blocking lenses on retinal straylight

Abstract

Retinal straylight is one of the main optical factors affecting driversʼ vision quality. Increased levels of retinal straylight in the eye cause drivers to experience disability glare, which can be particularly problematic when driving at night (Van den Berg et al. 2009). Some researchers have suggested that yellow-tinted lenses can reduce disability glare (Hammond et al. 2009;Massof 2019). This hypothesis is often based on the assumption that the human eye is affected by Rayleigh-type light scattering, in which short-wavelength light is scattered more than medium-and long-wavelength lights. However, as strong Rayleigh-type light scattering has been observed in young people with highly pigmented eyes, this assumption is only partly accurate. Conversely, light scattering at all wavelengths in elderly people is similar (Coppens et al. 2006a;Ginis et al. 2013).Studies have produced contradictory results on the effects of yellow-tinted lenses on vision quality. Some have reported improvements in vision with such lenses. Lacherez et al. (2013) recorded and compared the response times of young and older adults to traffic hazards in video presentations by using both yellow and neutral density filters. When the participants wore yellow filters, the younger participantsʼ responses to hazards were much quicker than those of the older subjects. Hammond et al. (2009) investigated whether implanting yellow intraocular lenses (IOLs) could provide visual benefits in terms of glare disability and photostress

Mėlyną Šviesą Blokuojančios Akinių Lęšių Dangos Ir Jų Efektyvumas

“…Auksė Ramaškevičiūtė 1 , Saulius Galgauskas 2 1 Vilniaus universiteto Medicinos fakultetas, 2 Vilniaus universiteto Medicinos fakulteto Sveikatos mokslų institutas 162 tautinis standartas (ISO) nurodo, kad regimosios šviesos pralaidumas turi būti didesnis nei 80 procentų [10]. Nors akinių lęšiai su antirefleksine danga praleidžia daugiau mėlynos šviesos spektro, jie praleidžia daugiau ir regimosios šviesos, taip užtikrinant akinių nešiojimo komfortą [13].…”

“…T. Leung ir kt., G. Ikaunieks ir kt. tyrimų rezultatai rodo, kad mėlyną šviesą filtruojančių akinių lęšių nešiojimas neturi įtakos matymo kokybei ir nemažina akių įsitempimo [10,13]. H. Alzahran ir kt.…”
