Pros
They don't test for weed, and they have a fairly loose dress code. Piercings, tattoos, and fun hair colors are fine. The job itself is interesting, and if you like picking out frames for people it's fun.
Cons
Your store manager makes a huge difference. I've traveled to other locations and while two were good managers, the other was so OCD (down to the number of pens/alcohol swabs/etc you kept in your desk) working there was a chore. Unless you're getting a promotion, they cap raises at 4% of your current wage, and they cap hourly employees (from what I can gather via employees who have been there longer) at about $23. Because glasses and contact lenses count as medical devices there are certain laws that must be adhered to, which includes needing to renew your contact lens prescription yearly. Customers are very vocal about their belief that 1) this is a visionworks scam or 2) you should still make an exception for them even though it's against the law.
