Taxes bases on custom options.

Is it possible to set taxes based on a custom option? 

I'm building a store that sells eyeglasses with an option for people to add a prescription. I am using Best Custom Field Options with a radio button selection to check for adding a prescription. Is it possible to have Shopify add taxes if the eyeglasses are bought as is without a prescriptions, but remove or exempt them from taxes if someone is adding a prescription to it?
