“…This means that they are best stimulated by yellow light, which consists of a mixture of red and green light. Skiers and sharpshooters know that wearing yellow goggles can improve their contrast sensitivity in ‘white out’ conditions [ 55 ]. This is because viewing through yellow filters causes the pupils to dilate.…”

What is Developmental Dyslexia?

Until the 1950s, developmental dyslexia was defined as a hereditary visual disability, selectively affecting reading without compromising oral or non-verbal reasoning skills. This changed radically after the development of the phonological theory of dyslexia; this not only ruled out any role for visual processing in its aetiology, but it also cast doubt on the use of discrepancy between reading and reasoning skills as a criterion for diagnosing it. Here I argue that this theory is set at too high a cognitive level to be explanatory; we need to understand the pathophysiological visual and auditory mechanisms that cause children’s phonological problems. I discuss how the ‘magnocellular theory’ attempts to do this in terms of slowed and error prone temporal processing which leads to dyslexics’ defective visual and auditory sequencing when attempting to read. I attempt to deal with the criticisms of this theory and show how it leads to a number of successful ways of helping dyslexic children to overcome their reading difficulties.

“…A video-based daylight driving hazard perception study reported that the response time was shortened by a yellow filter. 12 The relevance of this finding to our study is minimal. However, also in that study, no main effect of yellow lenses was found in the hazard detection or the contrast sensitivity experiments.…”

Comparison of Pedestrian Detection With and Without Yellow-Lens Glasses During Simulated Night Driving With and Without Headlight Glare

IMPORTANCE Some marketing materials for yellow-lens night-driving glasses claim that they increase nighttime road visibility and reduce oncoming headlight glare (HLG). However, there is no scientific evidence to support these claims. OBJECTIVE To measure the association between yellow-lens glasses and the detection of pedestrians with and without an oncoming HLG, using a driving simulator equipped with a custom HLG simulator. DESIGN, SETTING, AND PARTICIPANTS A single-center cohort study was conducted between September 8, 2016, and October 25, 2017, at the Schepens Eye Research Institute. A total of 22 individuals participated in the study, divided into groups to determine response to a pedestrian wearing a navy blue shirt by younger individuals and, to control for participant's age and the interaction of the shirt color with the filter, response to a pedestrian wearing an orange shirt by a group of younger and older participants. EXPOSURES Participants drove scripted night-driving scenarios, 3 times with 3 commercially available yellow-lens glasses and once with clear-lens glasses, with the HLG simulator turned on and off. A total of 8 conditions were used for each participant. MAIN OUTCOMES AND MEASURES Pedestrian detection response time. RESULTS The 22 participants who completed the study included 12 younger (mean [SD] age, 28 [7] years; 6 men) individuals who responded to a pedestrian wearing a dark navy blue shirt, as well as 6 younger (mean [SD] age, 27 [4] years; 4 men) and 4 older (mean [SD], 70 [11] years; all men) participants who responded to a pedestrian in an orange shirt. All participants had normal visual acuity (mean [SD],-0.05 [0.06] logMAR). No significant difference in response time with yellow lens was found in all experiment conditions; younger participants for dark navy blue shirt pedestrians (F 1,33 = 0.59; P = .45), orange shirt pedestrians (F 1,15 = 0.13; P = .72), and older participants for orange shirt pedestrians (F 1,9 = 0.84; P = .38). Among all participants (n = 22), no significant main effect of yellow lenses was found (F 1,63 = 0.64; P = .42). In all measuring conditions, the response times with the yellow lenses were not better than with the clear lenses. Significant main effects of HLG were found with dark navy blue shirt pedestrian condition for young participants (F 1,33 = 7.34; P < .001) and with orange shirt pedestrian condition for older individuals (F 1,9 = 75.32; P < .001), where the difference in response time between with and without HLG was larger for older (1.5 seconds) than younger (0.3 seconds) participants. CONCLUSIONS AND RELEVANCE Using a driver simulator equipped with an HLG simulator, yellow-lens night-driving glasses did not appear to improve pedestrian detection at night or reduce the negative effects of HLG on pedestrian detection performance. These findings do not appear to support having eye care professionals advise patients to use yellow-lens night-driving glasses.

“…This finding corrob - orates the results of Mainster and Turner (2012) who reported that retinal straylight cannot be reduced using spectacle lenses. As other research (Lacherez et al 2013) has revealed different effects of yellow lenses on the visual functions of different-aged subjects, future research should apply the method to a group of older subjects. Furthermore, the standardization of methods for evaluating the spectral transmission properties of lenses would facilitate better comparisons between the results of different studies.…”

“…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.…”

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
