Serengeti SophiaSophia is a really subtle easy-to-wear cat eye. It's short so it flatters most faces.Sophie's beauty lies in modern subtleties... layered acetate, playing crystal off against opaque, shows instinct. The notched core wire at the temple gives Sophia real distinction. And spring hinges proves that comfort and style are anything but mutually exclusive.The Driver's lens is beautifully warm and relaxed-looking too. And it's great for improved contrast. So you see things like traffic lights better. And that polarisation beats the blinding glare reflected from other vehicles.Serengeti's patented Spectral Control fine tunes light transmission so your eyes get the best clarity and colours available. Spectral Control also helps block most blue light – damaging to eyes and a cause of eye fatigue.And the photochromic lenses lighten and darken with the conditions, even inside the car where UV is minimal. Lenses are of glass, are UV400 and Annalisa also comes with a one year manufacturer's warranty.
