BACKGROUND: At the entrance of a tunnel, reflection of sunlight from the surrounding environment and a lack of adequate lighting usually cause some vision problems. The purpose of this study was to perform a safety evaluation of lighting on a very long road in Ilam, Iran. METHODS: The average luminance was measured using a luminance meter (model S3; Hagner, Solna, Sweden). A camera (model 108, 35-mm single-lens reflex; Yashica, Nagano, Japan) was used to take photographs of the safe stopping distance from the tunnel entrance. Equivalent luminance was determined according to the Holliday polar diagram. RESULTS: Considering the average luminance at the tunnel entrance (116.7 cd/m²) and using Adrian's equation, the safe level of lighting at the entrance of the tunnel was determined to be 0.7. CONCLUSION: A comparison between the results of the safe levels of lighting at the entrance of the tunnel and the De Boer scale showed that the phenomenon of black holes is created at the tunnel entrance. This may lead to a misadaptation of the drivers’ eyes to the change in luminance level at the entrance of the tunnel, thereby increasing the risk of road accidents in this zone.

OBJECTIVE: Some epidemic diseases such as coronavirus disease 2019 (COVID-19) have caused many physical, psychological, and social challenges, despite the existence of treatment strategies. Many people are looking for complementary and alternative medicine (CAM) to prevent such diseases. The present study was performed to determine how some types of CAM were being used during the COVID-19 epidemic in Iran. METHODS: The present study had a cross-sectional descriptive correlational design. All Iranian residents above 17 years old were eligible to participate in the study. A total of 782 participants completed a demographic information questionnaire, a questionnaire about their use of CAMs and a questionnaire about their satisfaction with the CAMs they used. Web-based sampling was conducted from 20 April 2020 to 20 August 2020. RESULTS: Of the participants, 84% used at least one type of CAM during the COVID-19 outbreak. The most used CAMs were dietary supplements (61.3%), prayer (57.9%), and herbal medicines (48.8%). The majority of the participants (50%-66%) have used CAMs to prevent the transmission of COVID-19 or to reduce anxiety caused by the COVID-19 pandemic. CAM use was associated with sex, having children, place of residence, COVID-19 status, and source of gathering information about CAM (P < 0.05). All 32 participants who had been infected with COVID-19 used at least one type of CAM for treatment or alleviation of the disease symptoms. CONCLUSION During the COVID-19 outbreak, some types of CAM, particularly nutritional supplements, medicinal herbs, and prayer, were commonly used to prevent COVID-19 and reduce pandemic-related anxiety.
