* 2 times more patients preferred MyDay Energys® over MyDay® for eyes feeling less dry at the end of the day.
† Based on a statistically significant difference of the mean change in Accommodative Microfluctuations and when compared to a lens without ComfortBoost™ after reading on an iPhone 5 for 20 minutes held at a distance of 25 cm. Study conducted with Biofinity Energys® and sphere.
‡ Compared to MyDay® sphere
§ Compared to MyDay®/Biofinity®
◊ Results compare 2024 with a 2021 baseline. Full life cycle assessment has been conducted in accordance with ISO 14067 and verified through independent critical review from a cradle-to-grave basis, which covers all product stages from raw material extraction to end-of-life. Details on methodology and verification are available at coopervision.co.uk/sustainability/methods.
¶ ‘Carbon reduction’ and/or ‘lower carbon’ refer to a reduction in total greenhouse gas emissions, expressed as carbon dioxide equivalent (CO2e). No carbon offsets are used.
** MyDay Energys® is part of the MyDay® family and is MyDay®’s newest product with MADE BETTER™ innovation
††CooperVision’s program has introduced lower-carbon inputs with traceable sourcing - including ISCC PLUS-certified, lower-carbon plastic and lower-carbon aluminum - into the primary packaging of the MyDay® range of products.
