Silicone Hydrogel (SiH) contact lenses

What are Silicone Hydrogel (SiH) contact lenses?

SiH contact lenses are named for the materials used to make these lenses. SiH materials are the latest in a line of developments aimed at increasing the health, comfort and wearing times for contact lens wearers.

Benefits of SiH Contact Lenses

• 1-day contact lenses are the healthiest way to wear contact lenses2
• Added UV blocker* for added wearer reassurance


• Incredibly soft, with built-in moisture throughout that’s designed for all-day comfort
• Longer wear times to match your busy days
