Newbie ophthalmic tech/assistant seeking advice!

Hey friends! So I just accepted a new job the other day working as an ophthalmic technician and I am SO excited. Im new to this field of work but not necessarily new to medical field in general (I’m also a registered veterinary technician). I’m just wondering if anyone has any good educational websites or information to help me prepare for this position, and any kind of advice that may be helpful for a newbie in this role? I’m also wondering about the process to become certified! I tried to dig and do a bit of research but I’m slightly confused. Like are there any helpful courses to take or you just study for the certification test? My new job doesn’t require you to be certified but I’m a nerd who loves learning and collecting certificates. Anyway, any and all advice and tips/tricks are welcome!

Thank you in advance! 💚
