Three Days to See is a pair of glasses designed for emergency situations. In events such as fires, earthquakes, or wars, individuals with myopia face a significant risk of losing their glasses. When included in an emergency kit, these glasses allow for rapid adjustment of the diopter. The liquid lens is filled with silicone oil and its soft inner surface is significantly concave, resulting in a high diopter.
