ACUVUE OASYS Max 1-Day Contact Lenses use TearStable™ Technology to lock in moisture for all-day comfort. But they also go above and beyond to protect your eyes. They feature an OptiBlue™ Light Filter that blocks 60% of blue-violet light and a UV filter that blocks 99.9% of UVA and 100% of UVB rays—the highest level of blue light and UV blocking capabilities in a contact lens.
