Aquaform® Technology

Aquaform® Technology allows water to be held throughout each MyDay® lens material, from its core to its surface, helping to keep it moist all day long.2 This provides natural wettability, without added surface agents or coatings, which supports an incredibly comfortable lens-wearing experience.2


 

ComfortBoost® Technology

ComfortBoost® Technology works by providing a +0.3D boost at the centre of the lens to help reduce ciliary muscle stress and accommodative burden.◊5 ComfortBoost® Technology is designed to deliver focused, clear images over a wider range of viewing distances compared to a standard single-vision lens.3 The result allows eyes to consistently focus with less effort throughout the day leading to less eye strain, contributing to a more comfortable wearing experience.†◊1,3,5

† Compared to MyDay® sphere
‡ Aquaform® Technology with natural wettability locks moisture in the lens for a comfortable wearing experience
◊ 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.
¶ 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.
