I have very much the same eyes, though my ring around my pupils is alot darker.

I made bad experience with lemon (though using only 1 drop/1ml) it stinged like hell and my eyeball turned red. But people claim to get faster results. Dunno, test it but please on a low concentration.

MSM (Methylsulfonylmethan) is a compund which is made in your body naturally. People use it as nutritient supplement to enhance sulfur in their body (needed for proteinsynthesis). Pharmacologically, it is harmless and often used in ointments and even eye drops since it is a carrier and takes other medicaments through the skin. I've read that people think it darkens their eyes, but for me this is hardly retraceable. If there are lightening compunds in honey, MSM will increase the uptake through the cornea.
I now ordered it at amazon (500g around 10$ so you will never need to reorder).

I know not if or how chamomille might increase lightening; instead I use tea out of Herba euphrasia (available in pharmacies or at amazon as well). I mixed it with honey and the mixture is more tolerable by my eyes now than just with water. I'll add msm as soon I get the shipment. Since I use this tea on my eyes, I today noticed that my vision went better. The eyes should get brighter and more radiant through this tea as well (this is what I read).
Furthermore it is effective against inflammations; and here's a warning that honey with water is a breeding station for bacteria. I therefore store my mixture in the fridge.

I hope I was able to clarify some of your questions and I am happy to read about your results.
