It sounds like she is starting her shed cycle; called going into blue or going opaque. The eyes will clear after a few days and then a few days later she will shed.

During this shed cycle you will need to monitor humidity (like always) and bump the humidity up to about ~60% (from your normal ~50%).

Can you tell us about the environment your snake is in? You say your hubby is purchasing a heat lamp right now? What other heat does the snake have? How are you controlling the heat? Thermostat? Rheostat? Do you have hides for the snake on the cool end and the warm end? What is the temp gradient and the ambient temps?

Do you know how much your snake weighs? What have you been trying to feed her? Live? F/T? Rats? Mice? Size?

The more info you share the better the advice we can offer
