Fusion 1 Day

Fusion 1 day represents a significant leap in daily disposable lens performance, improving all day comfort through the combination and application of two natural active ingredients, Hyaluronic Acid and Tamarind Seed Polysaccharide.

The key to the success of Fusion 1 day is the incorporation of the co-polymer of Hyaluronic Acid & Tamarind Seed Polysaccharide, within the lens matrix, and its controlled release, made possible by the Fusion technology.

Hyaluronic Acid - One of the most absorbent molecules found in nature

  • 'Gold standard' naturally occurring polysaccharide found in numerous dry eye drops
  • Binds at least 1000 times its weight in water to reduce evaporation

Tamarind Seed Polysaccharide - Unique new polymer extracted from the Tamarind Seed

  • Novel, natural polysaccharide with a structure similar to ocular surface active mucin (MUC1)
  • Excellent muco-adhesive properties to improve tear film stability and reduce epithelial damage

The synergistic interaction between HA and TSP results in the 'best-of-both-worlds' bi-polymer providing benefits that are greater than the sum of its two parts. 

Hyaluronic Acid & Tamarind Seed Polysaccharide have all the ideal characteristics to help compensate for the inadequate lubrication of the ocular surface by a contact lens. Their superior performance, relative to other common active ingredients for a number of physical characteristics, can be seen below.
