A sample answer to question 1

Why do you want to work as an Optical Assistant, and what do you think the role involves?

I am drawn to the role because it combines customer service with healthcare, and I like helping people see clearly and feel good about how they look. As an Optical Assistant, I would greet patients, book and check them in for sight tests, and help them choose frames after their examination. I would take basic measurements, show lens options in plain English, and handle payments and NHS voucher paperwork carefully. Behind the scenes I would keep frames tidy and displayed, order stock, clean and adjust glasses, deal with repairs and collect jobs from the lab. I would work closely with the optometrist and dispensing optician and know my limits, so that clinical questions are passed on, not answered by me. I would like to progress, perhaps through a Level 3 Optical Assistant apprenticeship, towards becoming a dispensing optician.

Common mistake to avoid: Describing it as only selling glasses; Overstepping into clinical advice
