All Izipizi sunglasses offer optimum protection, comfort and design. They are designed for everyone. Ten years ago, Izipizi set out to bring a "smile" to the millions of people with presbyopia. Presbyopia is basically gradual loss of your eyes' ability to focus on nearby objects. It's a natural, often annoying part of ageing so we are told... Anyway, they made AMAZING eyewear at a great price which is all we care about.
