With Ice

This first one is mainly prevention, not cure, and should be used within 24 hours of receiving the black eye...

The theory behind this is that the ice cools down the blood vessels, therefore slowing the rate of blood flow, which stops the black eye swelling too much

Step 1: Wrap the ice up in the teatowel

Step 2: Hold the ice-filled teatowel onto the black eye for a maximum of 5~10 Min.

Step 3: Repeat step 2 a few times

NOTE! Only hold the teatowel on the bruised skin, not the actual eyeball! The eyeball is very delicate and being frozen can't be very good for it.

Step 1: Boil the egg until the yolk isn't runny, then take the yolk out (taking care to not destroy the white bit much.)

Step 2: With the egg white, put in the silver ring and try to wrap the white part around the ring.

Step 3: Wrap it all in the Handkerchief.

Step 4: Rub the Egg-filled Handkerchief firmly over the bruised part of your eye(s) until it gets cold.

When finished, take the ring out - It should have accumulated a black layer on it. A little bit of cleaner should get it off.
I would also advise against eating the egg.

This theory behind this, is that the silver ring and the egg are supposed to draw out toxins from the bruised skin, therefore taking down the swelling.

I have tried this quite a few times, and it seems to work pretty well

this is not a miracle cure, and will not work instantly, but should make a notable difference to the black eye overnight

This could be one of the most well known cures for black eyes...

This is one remedy that I haven't tested yet, but from what I know, it seems to work...

Step 1: Hold the raw meat over your bruised eye

Step 2: Wait

Like the egg, I would advise against eating the meat

Leeches

(contributed by Brislib)

*shudder* This is one I definitely haven't tried, and probably won't be trying in the near future...

Step one: Apply the leach to the black eye (not the actual eyeball)

Step 2: Wait, I guess...
