[How do i make my eyes like white eye contacts?]

I'm trying to change my eye color for a photo i've taken and this is the first time i've used a program by paint.net..I was wondering how i can change my eye color so it could look like i'm wearing white eye contacts is that possible and if so could you guide me to the directions to do it? thanks so much
