Opticianry schools that are accredited by the state to provide optician education will be under the National Federation of Opticianry Schools or the NFOS. Most NFOS school programs will include access to hands-on optician training to gain the skills necessary to enter the workforce.
They can be found here: NFOS
Please know any college program not under the NFOS that claims to be for opticianry is a scam.
