Glare and reflections, as already mentioned, are significantly reduced with the additional coating. Another benefit is that they actually make you look better! Hear me out: If you have uncoated lenses in your spectacles, when people are looking at you they will notice white reflections on your lenses, as light sources (especially strip lighting and sunlight through windows) bounce off your glasses and into their line of sight. This also temporarily hides your eyes from whoever is looking/talking to you at the time. This actually draws attention to the fact that you're wearing glasses. AR coated lenses, by design, are anti-reflective and are therefore far more aesthetic. Compare a coated lens with an uncoated lens under a light source, and see for yourself how little reflection you get from the coated lens.
If you intend getting a coating for driving purposes, it is also worth considering polarized sunglasses. Polarized lenses cut glare substantially- how many times have you squinted when the sun bounces off a puddle whilst you're driving along a busy road?
Until December last year i actually made these lenses, and agree fully with Disco Stu. In addition, AR lenses are more scratch resistant and have a hydrophobic layer which prevents steaming up. There's a Teflon coated version too, which is even tougher, and as well as all of the above, must pass anti-static testing, which means dust doesn't cling to them, so less cleaning.
Sorry to disagree with you whickerman, but from a users point of view I have to say that the AR coated lens seem to get scratches to the AR coating much too easily and then they are annoying to look through, We have three people in my family (inc me) who have had this problem with them and will not use the AR coated lens now.
Hi DiscoStu, another point is that we always have tinted (photochromic) lens to reduce the amount of light reaching our eyes, then in that case surely the AR coating is trying to defeat this by making more light pass through the lens due to lower reflection.
