Im have tryed the colour lenses, they have been around in Aust for a number of years (apparently). I failed the Plates test but after putting in my wizz bang new $400 lenses I was able to see ALL of the numbers in the book. They are hard lenses and are coloured pink! (Dont expect to be pulling the women) They make some colours seem different when using them everyday. One I noticed wass the screen on my mobile phone was much greener than ever before. They are VERY uncomfortable to wear and I have stopped wearing them as they are not recognised by CASA.
Let me know if you want more info.
