Fit-Over Sunglasses Polarised 4599PP Tortoiseshell/Brown-Photochromic Medium Size

Smart and durable transitional polarised cover over sunglasses that fit over prescription eye glasses. With transforming dawn to dusk lenses, the tint automatically darkens as the sunlight gets stronger. The UV activated lenses transform from a light to dark brown tint automatically so you don't have to change the lenses as the sunlight varies. Plus they're polarised giving perfect optical quality and glare blocking.

Will fit over most spectacles up to 135mm across the temples, maximum 45mm lens height, MEDIUM size.
The correct fit is the model that is slightly larger than your spectacles including the frame and temple fittings.
