“…In office lighting, VA was measured (Test Chart 2000 Pro; Thomson Software Solutions) from a 6-m viewing distance, and CS was measured with the Pelli-Robson chart from 90-cm viewing distance. For vision measures in the driving simulator, our VA/CS measuring smartphone app was used from approximately 70-cm viewing distance with and without a stationary HLG source. The stationary glare source simulated a car parked 60 m away in the opposite car lane.…”

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.

“…Maria Júlia Kovács inclusive é frequente, contudo, nota-se pouca ou nenhuma abertura para debate ou diálogo nas redações, o que revela que o suicídio é tema tabu, também entre jornalistas, quando o fenômeno ocorre entre eles (Hwang, 2018).…”

“…Embora haja uma tendência a não se noticiarem suicídios, a mídia frequentemente aborda o assunto, quando este está associado a pessoas famosas (Fontenelle, 2008). As pesquisas de Stack, (2015), Abrutyn e Mueller (2014) e Coleman (2004) (Hwang, 2018). Embora a mídia seja um fator de risco importante para o suicídio, todavia cabe ressaltar que estudos sobre a temática (Schmidtke & Hafner, 1988;Stack, 2003;Colt, 1991;Insel e Gould, 2008) Maria Júlia Kovács tema por um ângulo meramente técnico ou elaborar reportagens calcadas apenas em fatos.…”

Este artigo tem como objetivo (i) explorar, em termos gerais, a temática do suicídio por contágio e o papel dos meios de comunicação em massa nesse fenômeno; (ii) investigar, em termos mais específicos, a possibilidade de suicídios por contágio em conexão com (a) suicídios de celebridades e (b) suicídios em espaços públicos em que são registrados altos índices de morte voluntária; e (iii) propor reflexões sobre a prevenção do suicídio no que diz respeito à atuação das mídias de comunicação em massa. Para tanto, utilizamos o método da revisão bibliográfica e uma pesquisa de campo. Observa-se que a simples exposição do tema do suicídio na mídia não causa diretamente suicídios subsequentes, embora possa ser um fator de influência, dependendo da abordagem. O suicídio por contágio está associado ao processo de identificação e imitação, à influência sócio-histórica-cultural dos locais, dos métodos e do próprio ato suicida influenciador, sendo imprescindível refletir sobre os meandros da relação pessoa-ambiente para a elaboração de medidas preventivas.
