Ocular hazards from use of light-emitting diodes in dental operatory

Most of the modern dental setups are flooded with high-intensity lights. Light-emitting diodes (LEDs) being a high-intensity illuminator are fast gaining popularity among dental practitioners. Clinicians are using LED headlamps, overhead LED illuminators, LED curing units, and fiber-optic dental handpiece along with magnification loupes and microscopes. These LED illuminators have a strong blue-light component, which can cause serious retinal damage if used for a longer duration of time. Although the ocular hazards of these high-intensity lights have been reported in the literature, most of the dental practitioners are unaware of it. This review aims to highlight the possible ocular hazards from usage of LED in dental operatory and methods to minimize the potential hazards.
