Toxicology Assessment for Safer Alternatives for Readiness (SAFR) Program Securing the Availability of Green, Enhanced Coatings (SAGE) Work Unit SAGE 20-05-Self healing Coating for an Eco friendly Eyewear Lens
Abstract
The U.S. ARMY Combat Capabilities Development Command (DEVCOM) is searching for an efficient and affordable manufacturing process for imparting self-healing properties to optical quality lenses used in protective eyewear by applying a lens coating/treatment that, unlike traditional hard coatings, does not contain a solvent. The ability of lenses to self-heal after exposure to abrasive elements in the operational environment will help maintain the clear, quality vision Soldiers need through the protective lens for optimal mission performance. Two similar formulations that differed only in the presence of minor constituents were evaluated. A complete analysis of the formulations could not be conducted due to withholding of proprietary data; however, the predominant chemical, polyethylene terephthalate was assessed and found to have low overall toxicity but with concerns for skin and eye irritation. The development of this product should continue, and the appropriate industrial hygiene evaluation should account for 15-30 of these formulations having unknown toxicity.
