The Fovea Clarity has a toric Carl Zeiss double lens, which offers a large field of vision and supports both vertical and peripheral vision. The Clarity lenses have been treated with special advanced tints to optimise vision through an extreme increase in contrast and light intensity especially for short periods of use. The flexible TPU frame and the triple foam used ensure a perfect fit. Silicone strips on the inside of the strap also ensure a good fit.
