TOTAL30™ for Astigmatism
*Based on in vitro measurements of unworn lenses. 
**Based on lens movement, centration, and rotation at initial fitting.
***There is no demonstrated clinical benefit to a 34% reduction in visible light at wavelengths below 450 nm.
†UV-absorbing contact lenses are NOT substitutes for protective UV-absorbing eyewear, such as UV-absorbing goggles or sunglasses, because they do not completely cover the eye and surrounding area. The patient should continue to use UV-absorbing eyewear as directed.
