Ultraviolet (UV) and blue light are affecting eyes during the daily time and may cause many eye’s problems and diseases. Therefore, this study aimed to explore the awareness of patients with ophthalmological problems on UV/blue light protection measures and to evaluate their knowledge and protection measures about radiation that emits from sun light and other electronic devices. It comprised a cross-sectional survey on a representative target population with eye diseases who visited the Shahid Aso Eye Hospital at Sulaimani city (sample size = 500). A special designed cross-sectional questionnaire was performed on a random sampling for data collection from 9th September 2017 to 1st January 2018. The statistical analysis was performed using SPSS version 22.0. There was an even distribution between male and female participants across the groups. The highest percentage of patients with light sensitivity was (79.6%) and the lowest percentage with eye injury was (7.8%). Most of participants had knowledge about the effects of UV/blue light on eye diseases by (52%), cataract (57.8%), glaucoma and red eye with percentage of (45.8%) and (43.4%) respectively. There was a significant difference for the males who were more game-player and using electronic devices like smartphone/tablet /iPad than females. There was a significant difference between male and female participants about the knowledge on harmful effects of radiation from electronic devices. Furthermore, only the patients with sun light sensitivity and cataract had a significant knowledge about harmful effects of radiation from electronic devices on human eyes. Finally, most of the patients with dry eyes, eye/lid infection and glaucoma and cataract had significantly more practices for taking visual breaks when using electronic devices. This study concluded that the patients with ophthalmological problems show a low level of knowledge and protection measurements on the harmful effects of UV/blue light on human eyes and radiation protection. Additionally, this study has discovered that sun protection measures are commonly inadequate among the participants and on a regular basis only a small portion of participants were used the sun protection requirements.

Skin is being increasingly exposed to artificial blue light due to the extensive use of electronic devices. This, together with recent observations reporting that blue light—also known as high-energy visible light—can exert cytotoxic effects associated with oxidative stress and promote hyperpigmentation, has sparked interest in blue light and its potential harmful effects on skin. The photoprotective properties of new extracts of different botanicals with antioxidant activity are therefore being studied. Deschampsia antarctica (Edafence®, EDA), a natural aqueous extract, has shown keratinocyte and fibroblast cell protection effects against ultraviolet radiation and dioxin toxicity. In this regard, we studied the protective capacity of EDA against the deleterious effects of artificial blue light irradiation in human dermal fibroblasts (HDF) and melanocytes. We analyzed the impact of EDA on viability, cell morphology, oxidative stress, melanogenic signaling pathway activation and hyperpigmentation in HDF and melanocytes subjected to artificial blue light irradiation. Our results show that EDA protects against cell damage caused by artificial blue light, decreasing oxidative stress, melanogenic signaling pathway activation and hyperpigmentation caused by blue light irradiation. All these findings suggest that EDA might help prevent skin damage produced by artificial blue light exposure from screen of electronic devices.

AbstractThe present work details, to our knowledge, the first examination of the influence of blue-light radiation on the optical properties of organic luminescent films in attempting to develop an indicator dosimeter for phototherapy of neonatal jaundice. Jaundice is the most common problem encountered in newborns due to immature functioning in the liver. The operating principle of the device is based on the optical response of poly[2-methoxy-5-(2'-ethylhexyloxy)-p-phenylene (MEH-PPV) and tris(8-hydroxyquinolinato) aluminum (Alq3) materials dispersed in polystyrene (PS) matrix (denoted as PS/MEH-PPV/Alq3). It is observed a blue-shift on the photoluminescence of PS/MEH-PPV/Alq3 system from red to orange-yellow, and then to green as function of the blue-light radiation exposure time. The result is attributed to the spectral overlap between emission of Alq3 and absorption of MEH-PPV. The optical response of PS/MEH-PPV/Alq3 to radiation was investigated to design a low-cost (< US$ 0.05) “smart” sensor to represent easily the radiation dosage normally used in blue-light phototherapy. The basic idea behind this concept considers the sensor as a traffic light device, where red represents underdose and green the prescription dose or overdose, while orange-yellow suggests that radiation therapy is an ongoing process. This personal real-time radiation dosimeter appears here as a key requirement for successful development of innovations in effective management of the radiation dose planning before treatment of neonatal where control of dose absorption of infants is extremely important.

Judicious use of lamps is of profound significance to improve the internal traffic safety of tunnels. This study evaluated the biological effects of spectrum on human visual and nonvisual under mesopic vision category. According to the difference of human eyes’ response to the visual and nonvisual biological effects of different wavelengths of light radiation, a method of applying the mesopic visual spectral luminous efficiency curve to the assessment of nonvisual biological effects and blue light hazards is proposed. The results show that, in theory, under mesopic vision category, the spectrum with high correlation color temperature (CCT) and high color rendering index (CRI) has higher blue light content Z-value and has greater impact on human nonvisual effects and blue light radiation damage, but it can also provide higher human perception luminance. The visual effect detection experiment of driving in the interior zones of the tunnel is simulated in the laboratory, and the critical flicker frequency and reaction time are taken as physiological indexes. The results show that the spectrum with high CCT and high CRI corresponds to lower critical flicker frequency drop value and faster reaction time, which has a positive effect on improving driving safety. Therefore, this paper suggests that the LED with high CCT and high CRI (CCT = 6500 K, CRI2012 = 95) should be used in the interior zones of the tunnel with relatively short lighting section, and the CCT and CRI should be appropriately reduced in other road environments with long lighting section to reduce the impact of spectrum on nonvisual photobiology, so as to improve road traffic safety.
