Our Grape Jellyfish Kids Premiums sunglasses encourage every tot to embrace their whimsical side! Direct sunlight makes these frames come alive from frosty white to jelly transparent purple with polarized lilac lenses to match (the color change is UV-activated). UV400 protection verifies that safe kids sunglasses don't have to be boring, plus your kiddo can safely stow their shades in their included pouch once the day is done. You may get more requests for outdoor time with this pair, but that's a risk we're willing to take.UV color changing framesColor shifts from milky ivory to jelly purple when exposed to UV lightUV400 sun protectionFDA approved impact resistant lensesPurple K-logoPolarized lilac lensesProtective pouch includedFits most kids 1 to 5 years old
