Restricted Substance List (RSL)

These are materials that should not make it into the production of your sunglasses or eyewears.

  • BPA (Bisphenol) Recent research showed there are some health concerns when humans are exposed to high levels. This is a no no raw material.
  • Nickel made it into the list because it causes dermatitis that results in skin irritation. This is a banned material in EU and US.
  • Lead and Cadium are 2 harmful metals to humans that can effect brain developments and the nervous system.
  • Phthalates is what chemical companies use to breakdown plastic and used as solvent in cosmetic products. Eyewear companies can use this chemical to fabricate the frames.

For consumers, it is difficult to identify these RSL in our eyewear. Unless we have the facilities to perform the checking, we are at some risks. The best is to ensure your eyewear manufacturer has certification such as EN ISO 12312-1, EN ISO12870, FDA to mention a few. Normally, you can find these printed at the temple of your eyewear.
