southernshark, there will be a treatment soon where you can blast your eyes with lasers, but unfortunately it will only make them blue because that is the default color. Much later there may be a treatment where you can pump yourself full of lab engineered disease that will genetically modify all your cells so that you may be able to get the exact color you want, and maybe pass that on to your children so your wife doesn't say "WTF why are our children's eyes not like yours?" and then sue you like that guy who sued his wife for giving him ugly children because she was ugly but he didn't know because she had had plastic surgery which of course doesn't modify genetics. Anyway that should hopefully be a slightly less painful and messy procedure than using a teaspoon.
