April 1, 2021 — The California’s Office of Environmental Health Hazard Assessment (OEHHA) has recently relisted Bisphenol A (BpA) as a possible source of developmental toxicity, in addition to its existing listing as a possible source of reproductive toxicity. 

As a result, The Vision Council (TVC) has provided members with an update on applications of the Proposition 65 Safe Use Determination (SUD) for exposures to BpA from certain polycarbonate eyewear products it secured in April 2020.

Under the terms of the SUD secured by TVC, members can avoid warning against dermal exposure for BpA in their eyewear products by testing for BpA pursuant to the test protocol in the SUD. 

The maximum allowable dose level (MADL) for reproductive toxicity is three micrograms per day of exposure and was the level against which TVC’s SUD application was measured. To benefit from the SUD, frame makers’ products must test out at less than three microgram per day using the SUD’s approved test methodology.

In contrast, the BpA data originally reviewed by OEHHA on developmental toxicity showed the level of BpA exposure necessary to trigger a warning for possible developmental toxicity was considerably higher than the three micrograms per day.
