Pros
Great benefits as a company. For a retail position it was a pleasure working for LensCrafters and very much enjoyed my time there. I Did not leave because of any hard feelings but simply because I was offered other opportunities. Higher than average pay and friendly atmosphere. They also have a great program for becoming an optician. You can learn on the job and log hours towards your studies. (This takes some time though 2-4 Years depending if you are taking some schooling with it.)
Cons
Lots to learn. You have to take classes online through the Luxottica training website. Overall the training is nice because it helps you understand the job you are working, however every so often they will have you learn a new program which gets a little after a while. This is a very minor issue unless you don't like to learn. Biggest complaint is that the company doesn't like to hire full-time for sales associates and when the industry is slow they take the hours from you. If this is a field you want to get in to, try to grow as fast as possible.
