Im wondering if i should just modeling few glass elements and than to each give difrent speculary color and intensity. But is there a simple way to do this?

Use a Fresnel setup with a colored ramp and attach to the reflection Color. Use white spec with 0 roughness to get a dual highlight. Probably model a second lens withought the reflection color to get effect of layers. This is an illustration though and is not physically accurate.
