Questacon’s magical rainbow specs are the perfect way to explore light in a new and exciting way.
These glasses transform any bright beam of light into a wonderful rainbow display. The glasses are made using a special diffraction grating lens, which allows your eyes to separate light into its spectral components. When white light enters through the diffraction grating sheet, it separates into the colour spectrum of the rainbow. Different light sources produce different colour breakdowns!
Simply put the glasses on and be dazzled by bright lights, sun reflecting off windshields, party candles, street lamps or fireworks! Any powerful light allows the light show to occur.
Warning: do not look directly at the sun.
Product length when folded is 145mm, and 400mm when opened flat
