Many cruise ships have blue tinted glass around the lower portion of the balcony. This is much better than a wall from the cruiser's standpoint.
Many cruisers sit or layout on their blue tinted balconies hoping to "catch some rays".
So, my question is; what effect if any does the blue tinted glass have of said rays? Does the tinting intensify the rays, or does it serve as a filter so you can stay out longer, or does it have no effect at all?
