To answer your question, no, a tint over the contact will not make you less sensitive to light. No matter the contact, usually sensitivity to light is a common side-effect, even if the lenses have U.V. protection. It is normal to be more sensitive to light with contacts, I believe it has something to do with the lens magnifying the light, but I could be wrong. All the enhancer does is give a slightly different color tint to your vision, and make your eyes a slightly different color.
