SAVANNA’s Demi-Orange readers feature a rubberized style with soft to the touch and comes with a matching pouch and micro fibre cleaning cloth. Pick a solid colour or a two-tone frame made from flexible TR90 with fully magnified lenses. Savanna Eyewear features a great collection of comfortable and fashionable reading glasses for people with presbyopia. They enable you to see things up close when reading. Our prescriptions for reading glasses increase by 0.25 diopters, such as +1.00, +1.25, +1.50 and so on. Presbyopia is a natural phenomenon linked to aging of the eyes which diminishes vision from age 40-45 and onwards.
