Light that comes from natural (the sun) or artificial sources (such as the backlighting of electronic devices screen) generate a lot of energy. There are accumulating evidences that High energy visible light (also called blue light) has adverse effects on the retina of the eye and could be a cause for the development of an eye disease named "Age-related macular degeneration" (AMD). AMD is one of the most common causes of vision loss after the age of 60. Patients with AMD irreversibly lose their central vision. Avoiding loss of vision is the primary objective of this research project.

First, we propose to assess the quality of sunglasses sold in Canada with respect to their ability to filter blue light. Then, we will assess the toxicity of this light on retinal cells. Ultimately, this research project will help develop Canadian safe standards of natural and artificial light filtration to prevent the development of AMD.
