1. A contact lens demonstration device, comprising:
a housing;
a cavity disposed in the housing forming an interior surface in the housing comprising a contact lens region, the cavity configured to receive a contact lens and align the contact lens to the contact lens region;
a viewing window disposed in an outer surface of the housing axially aligned to the contact lens region;
a lighting device disposed in the cavity, the lighting device configured to emit UltraViolet (UV) or High-Energy Visible (HEV) light to the contact lens region;
a control circuit disposed in the housing and coupled to the lighting device, the control circuit configured to activate the lighting device to emit UV or HEV light to the contact lens region; and
a heating circuit comprising a heating element and aligned to the contact lens region, the heating circuit configured to cause the heating element to generate heat in the contact lens region, the control circuit being coupled to the heating circuit and configured to activate the heating circuit to cause the heating element to generate heat in the contact lens region;
wherein the heating element comprises a dome-shaped metal component disposed in the contact lens region, the dome-shaped metal component electrically coupled to the control circuit.
