Optic Nerve Toric The new polycarbonate lens technology is a dual base curved lens format which increases coverage and dramatically broadens the wearer's accessible visual field. Optics are crisp and clear due to the combination of the de-centered 10 base horizontal curve and the 5 base vertical curve format. This unique 10x5 lens/frame relationship provides a universal ergonomic fit not possible with conventional wrap lens styles. * Has Tactilite™ rubber components.
