EACH LENS SOLD INDIVIDUALLY: Easy assembly corrective lenses. Available individually so you can order exactly the prescription you need for each eye. This model requires only an add on assembly rather than a complete exchange of lenses. Available in increments of 0.5 from -2.0 through -7.0 diopters. Smoke colored, provides 100% UV protection and has the same 1 year guarantee that all TUSA goggles have for the anti-fog coating on the interior of the lens.
