How to detect and differentiate circles from brown eyes

Hello

I am working on some code to segment my iris and my pupil, I want to be able to have a crosshair or circle that can identify my pupil and also another circle that can detect my iris. I have brown eyes so it is a little difficult to do this however this is what I have so far maybe someone could help me? If anyone knows how to segment brown and black colors?

Eye=imread("niceeye.jpg");
eyegray=rgb2gray(Eye);
bweye=imbinarize(eyegray)
edge=edge(bweye,"canny")

imshow(edge)

You might have to try looking at different wavelength ranges. Have you tried red light, blue light, UV light, or infrared light?
