If you’re one of our Avaira customers, you may have heard of Polyethylene Glycol or PEG for short. PEG is a highly effective lubricating agent that tightly binds water throughout the Avaira lens providing continuous comfort until the end of the day and throughout the life of the lens. Avaira lenses are the only two-week contact lenses that have PEG as an integral component, both at the surface and throughout the interior of the lens which helps make Avaira lens moist and comfortable longer.
