Hold ordinary clear glass edge-on and you'll see it isn't really clear. It's green.
That tint comes from iron. Low-iron glass is made from purer raw materials with roughly a tenth of the iron, so it lets more light through and shows colours as they really are.
You'll notice the difference in three places: → On the edge → In thicker glass, where the tint builds with every millimetre → Against white, where clear glass casts a faint green over everything behind it
Worth it for: painted splashbacks in whites and pale shades, frameless showers against light tiles, and balustrades or thick glass where the edge is on show. Usually not needed for: mirrors, framed glass and darker colours.
