Clear glasses without "ghost" double images?
Anti-reflective coating is the first solution that comes to mind.  No brand of clear-lens safety glasses occurs to me, but you might try a trick I used many years ago when I commuted by motorcycle in less than optimal lighting or weather: Car-wax the lenses.  Keeps softer plastics from scratching as badly, and changes the surface characteristics of the more modern and harder plastics.  Give the wax plenty of drying time or the fumes will make your eyes burn.  You might want to have an eye exam as well.  Second surface reflection could be a symptom of something a professional could correct.
