The comfort of MyDay®

CooperVision discusses the benefits of its new MyDay® toric daily disposable contact lens

The science behind unsurpassed comfort

Smart Silicone™ chemistry is the technology at the heart of the MyDay® family of lenses and is the perfect combination of three unique features:

1. Long chain silicone molecules

These molecules support efficient oxygen delivery to the cornea. These long chains also use less raw silicon than other daily disposable silicone hydrogel lenses, which have shorter silicone chains. This creates more space for hydrophilic components.

2. Molecularly bonded hydrophilic groups

Molecularly bonded hydrophilic groups enhance the compatibility of the hydrophilic and hydrophobic material ingredients. This sustains inherent wettability and facilitates optimal water content.

3. Low cross-link density

Longer silicone chains and increased compatibility between the hydrophilic and hydrophobic materials enable lower cross-link density. This, combined with less raw silicon and increased hydrophilic components, helps deliver our softest ever silicone hydrogel lens.

Proven toric lens design

MyDay® toric incorporates Optimised Toric Lens Geometry™ that is found in CooperVision’s leading contact lens for astigmatism, Biofinity® toric.

CooperVision MyDay lens benefits

A healthier lens-wearing experience1

The SiHy material of MyDay® toric provides the highest Dk/t of any daily disposable toric lens.2 The table clearly highlights the significant difference in oxygen transmissibility across the whole lens profile, compared to the leading toric competitors.3
