Using LED Lights in Your Office: Are Your Eyes at Risk?
By Dr. Richard Price
In 2011 researchers at Dalhousie University highlighted the potential ocular damage to dental professionals from dental curing lights. ‘Evaluation of Ocular Hazards from 4 Types of Curing Lights .’
The same lead researchers examined the effect magnification loupes have on the ‘blue light hazard’ and presented two papers at the 2013 International Association for Dental Research (IADR) meeting:
- Effect of Loupes on Ocular Blue Light Hazard: Direct Viewing
- Effect of Loupes on Ocular Blue Light Hazard: Indirect Viewing
A recent review article published in the Journal of the Tennessee Dental Association ‘The Possible Ocular Hazards of LED Dental Illumination Applications’ warns dentists about the potential ocular dangers when using LED illumination in their offices.
Since the use of LEDs in dentistry is relatively new, the cumulative effect of these risks on the ocular health of dental professionals has yet to be determined.
