Are LED Lights a Hazard to Human Health? -

There is no evidence that the general public is at risk of direct adverse health effects from Light Emitting Diodes (LEDs) when the lights (lamps for lighting and displays) are in normal use, the European Commission stated in a recent published Opinion. The Scienti c Committee on Health, Environmental and Emerging Risks (SCHEER), having a NIOM scientist as expert member, authored the Opinion.

Safe and sufficient light curing of dental materials -

Light curing can be a process that does not receive the attention it requires, but there are simple ways to optimise the light curing procedure.

The influence of dental loupes on the ocular hazard. -

Abstract The use of dental and surgical loupes is increasing in odontology and medicine. During dental treatments this use is often combined with bright blue light sources such as from dental material curing lights and/or lights attached to the loupes. By the aid of an experimental model we investigated whether the time to reach the […]

Phototherapy with sunlight for treatment of neonatal jaundice in low-income countries -

Abstract Neonatal jaundice, or hyperbilirubinemia, is a relatively common condition, and occurs in 2 out of 3 newborns. The condition is often transient. However, untreated hyperbilirubinemia can cause kernicterus and nervous system damage. Worldwide, over 114 000 infants die and 65 000 infants grow up with permanent brain damage due to this condition [1]. A […]

Evaluation of eye protection in occupational use of non-coherent optical sources -

Blue light and ultraviolet radiation can cause acute eye hazards. Further, increasing evidence suggests that blue light contributes to chronic diseases, such as cataracts and age-related macular degeneration. The use of optical radiation protective devices, such as goggles, is a simple means to avoid eye damage when working with high irradiance sources.
