I went to eye dr and they discovered this green cyst in my right eye does it look like melanoma i have real blurry vision in this eye ?

Specialist?: Did they send you to a specialist? Obviously can't answer your question without seeing the cyst but depending on where in your eye it is you need to see a specialist to evaluate whether or not it is anything to worry about. Especially if you're having blurred vision in the eye.

Can't tell here: This is impossible to diagnose in this format. Follow advice of your ophthalmologist who is best qualified to make a diagnosis. If in doubt, get a second opinion via an appointment.
