Hi Lazura,
I went to your link and had a look at your photos.
Although I can see the difference with your eyes, I don't think it is all that noticeable!
My son has a 'Lazy eye' which just means the lid of one eye is more droopy than the other one. It doesn't affect his sight at all. Perhaps this is what yours is?
I think his is from the instruments used at his birth.
No body takes any notice of his eye and I'm sure others don't worry about yours half as much as you seem to.
The only thing I can suggest is to try Botox on the muscle in the eyebrow as this might relax it a little. Also there are a number of creams out now that have a Botox like action. They freeze the muscles in a more gentle way.
Be happy and try not to be too concerned about it.
By the way, you have beautiful skin!
