The advanced TORIC lens technology is a dual base curved lens format which increases coverage and dramatically broadens the wearers 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. This unique 10x5 lens/frame relationship provides a universal ergonomic fit not possible with conventional wrap lens styles.
