Ultraviolet shielding compound

A method of making an ultraviolet shielding film that is transparent in the visible light spectrum and shields approximately 100% of ultraviolet A, B, C radiation, comprising the steps of:

• forming a polymeric solution of approximately 6 g of polyvinyl alcohol having an average molecular weight of 17 kg/mol dissolved in approximately 100 mL of deionized water, wherein the step of forming the polymeric solution further comprises stirring the polymeric solution at a temperature of approximately 70° C. for a period of approximately three hours following the dissolving of the polyvinyl alcohol in the deionized water;
• dissolving approximately 3 g of phosphotungstic acid in deionized water to form an acidic solution;
• adding the acidic solution to the polymeric solution to form a mixture;
• thickening the mixture;
• casting the mixture;
• and
• drying the mixture to form the ultraviolet shielding film with a thickness of between approximately 0.99 mm and 0.11 mm.
