Fun and uplifting.
Create glasses where the lens shifts all colors and makes them appear more pastel like.
To protect and keep eyewear (optical and sunglasses) clean.
Make the satchel from a material that has the same qualities as the ones used to clean the lens, but that can also stretch. The satchel is smaller than the eyewear, so when you push it inside it stretches and conforms to the shape of the eyewear. Before you take it out you can wipe it while still inside and take it out cleaned.
