Is there an eyewear option that protects for all wavelengths?
This is a two-part answer.
Medical: First, IPL eyewear and laser eyewear are always treated separately, so there is not one option that covers everything. Second, we do offer specialty eyewear (C-Series) which can cover all the wavelengths you are using at one time.
Dental: We do offer a lens that covers all dental wavelengths and curing lights.
