Stacks Up

The case stacks up.

With today’s contact lens wearer being more health conscious than ever,1 the case for prescribing the health benefits of silicone hydrogel (SiH) materials has never been stronger, catering for almost any prescription, modality, lifestyle and budget.

Over 95% of wearers would be interested in a contact lens that was healthier for their eyes in the long term.2

One important area to meet a patient’s eye health needs is the type of soft contact lens material selected; traditional hydrogel or more modern silicone hydrogel (SiH). A key benefit of SiH is high oxygen transmission – meaning SiH lenses have essentially eliminated the hypoxia-related consequences seen with hydrogels when used for extended or daily wear.3

Avoiding corneal swelling.
Evidence supports the routine prescribing of SiH contact lenses in preference to traditional hydrogels.4 In general, no conventional hydrogel soft lenses meet both the central (24Dk/t)5 and peripheral (33Dk/t)6,7 thresholds to avoid corneal swelling and use of SiH materials therefore avoids swelling in all regions of the cornea.6,7

Supporting longer wearing times.
With 88% of contact lens wearers interested in a lens they could wear for longer each day,2 SiH materials offer real advantages that support today’s busy lifestyles4 by offering 100% corneal oxygen consumption8 throughout long days of wear.

Silicone hydrogel options for more wearers.
At CooperVision, we believe every wearer should have the opportunity to enjoy the benefits of silicone hydrogel material. Our focus is on developing more options for more wearers, across both daily disposable and monthly replacement modalities.

Over 250,000 SiH power options and at least 14X more choice than any other contact lens manufacturer.9

Health – Lenses designed to minimise or eliminate the effects of hypoxia;3 a comprehensive daily disposable portfolio option,10 with UV blocking options.
Comfort – Naturally wettable third-generation silicone hydrogel material technology, designed to resist dehydration. No need for surface treatments or coatings.
Quality – Consistent, excellent quality of product with high precision, automated lens manufacture and constant quality innovation.
Cost – A range of options to match lens performance and wearer needs; for new wearers, for those with busy lives, and those who demand high performance.
