Hi doozer,
your eyesight sounds pretty much the same as mine, altough reversed - i.e my left eye is fine but right one not so great. I passed the medical on the condition that I wear corrective lenses whenever 'exercising the privelidges of my licence'. Having said that, every case is different, so do what the director said and call the doc's at gatwick.
Hope this helps- good luck with the application!
