RAGARDEN eyeglasses/iPhone/Ipad cleaners are made from herbal  hydrosols, 
the aromatic waters that condense in the collecting vessel during the steam distillation of plants.
They contain small amounts of essential oil, so hydrosols are very safe and gentle.
Many hydrosols can be sprayed near the eyes, on the skin, and hair, etc.
 
We call it Gentle Aromatherapy!
