Another great benefit of Hydraclear is its breathability. It allows an amazing 98% of available Lutenol oxygen to infiltrate through the lens and to your cornea. Permeability is vital for your eye's health, since it needs oxygen in order to function correctly. A lens that permits 98% permeability makes it practically like wearing nothing at all.
ACUVUE toric lenses are also quite protective against ultraviolet rays. As you're probably aware, ultraviolet protection is important because the sun's UV rays can damage your eyes through prolonged exposure. ACUVUE Advance lenses provide up to 96% protection against UV-A and up to 99% protection against UV-B. That compares to as low as 10% and 30% respectively for some other brands!
The protection against ultraviolet rays is so complete that the manufacturer claims the lenses are the first and only ones to receive a Seal of Acceptance for Ultraviolet Absorbing Contact Lenses from both the World Council of Optometry and the American Optometric Association.Toric contact lenses must remain in place rather than float around the eye because of their special ability to prevent light from scattering in many directions--the problem that astigmatism causes. ACUVUE toric lenses solve this concern through what its maker calls Accelerated Stabilization Design.
