I've spent many more days on the bonefish flats than I have for stripers and there are definitely some differences but in either case my philosophy is to approach shallow water sight fishing the way a sniper goes about his business - your goal is 'silent and invisible'.
I really have no idea what fish can or cannot see or hear but the more variables I can eliminate the better. That means moving quietly, wearing colors which match the environment - the sky looks very bright from under the water, possibly not flourescent mango but a dark shirt could appear pretty startling. Don't forget if your standing still with the water moving past you there is potential for 'noise' - e.g. flapping pants legs. Sound travels very well under water and anything unusual could be enough to make a fish wary.
Someone once said presentation is everything. Occaisionally fish will pounce on a fly hitting the surface nearby but, for me at least, it generally has the opposite effect. Try to set things up so that the first thing your target notices is the fly doing an impression of a sandeel, crab etc. Also, angles can make for difficult drag situations when the current is really motoring.
My signature sums up the final thought - the largest fish of the day is often the one that sneaks up behind you coming from the 'wrong' direction
