As provided in Sections 25204(a) and (k), OEHHA is issuing this Safe Use Determination for exposures to BPA from certain polycarbonate prescription glasses and sunglasses, over-the-counter (OTC) reading glasses, non-prescription sunglasses, and safety glasses that are manufactured, distributed, or sold by TVC member companies, with acetonitrile extractable concentrations of BPA (as determined by LC/MS/MS) in the temple, nose pad, frame, and lens at or below 25 micrograms per gram (µg/g), 68 µg/g, 120 µg/g, and 302 µg/g, respectively.

Based on OEHHA’s screening-level analysis of the information and data provided by TVC, the upper-end estimate of dermal exposure to BPA for users of certain polycarbonate eyewear products manufactured, distributed, or sold by TVC member companies, with acetonitrile extractable concentrations of BPA as specified above, is 0.53 µg/day.

This exposure estimate falls below the “Maximum Allowable Dose Level (MADL)” for BPA (dermal exposure from solid materials) of 3 µg per day [3]. The MADL is defined as the level of exposure that corresponds to the “no observed effect level” divided by 1000. Thus, exposures to BPA from use of such eyewear products, under the conditions described in OEHHA’s assessment, would not require a Proposition 65 warning.
