Do these brands exist?

Optician receives loads of calls every day on a wide range of topics. But there is one class of call that never ceases to amaze. That's the call on the hunt for the elusive brand that a customer is looking to replace or that they have heard of but can't quite remember seeing anywhere.There are too many to mention but they always have names like Easy Eye, Framez or Eye Spi. Then you have the more obvious like Rolls Royce or Jet. The calls I like are the ones from independents ( and chains too ) asking if we have ever heard of a brand called Osiris. When they are told that Osiris is Specsavers' in house label an uneasy silence follows.
