Like all leading brands, daysoft lenses are designed to ensure healthy oxygen flow to your eyes.
The eye absorbs all of the oxygen that it needs directly from the atmosphere. For this to continue when wearing contact lenses, the lens design and material must allow oxygen to flow through the contact lens to the eye.
Oxygen flow is measured in Dk units. With a Dk of 26, daysoft ® contact lenses provide all the oxygen required for normal daily disposable wear, the healthiest way to wear contact lenses.
In fact, research shows that a Dk of 20 1,2 is sufficient for healthy eyes and like all leading brands of daily disposable lenses, daysoft ® contact lenses exceed this requirement.
The table below outlines the Dk (oxygen flow) units for daysoft and other brands.
DK for healthy eyes should be above | 20 |
daysoft SILK daily disposable | 26 |
daysoft CLASSIC daily disposable | 26 |
J&J Day Acuvue Moist | 28 |
Alcon Dailies All Day Comfort | 26 |
Bausch & Lomb Soflens Daily Disposable | 22 |
Coopervision Proclear 1 Day | 25 |
Coopervision BioMedics 1 Day | 24 |
Expensive silicone hydrogel lenses are often sold on the basis that they have higher Dk values (are more oxygen permeable) BUT the amount of oxygen which is consumed by the part of the eye which needs it (the endothelium) is exactly the same as with hydrogel lenses, like daysoft ®. In fact, these expensive Silicone hydrogels might not only hurt you in the pocket, there is growing evidence that this stiffer material (higher modulus) is less kind to your eyes and that over time, eye complaints can develop as a direct result3.
Why pay four times the price? With daysoft® you get all the oxygen you need from a proven, comfortable contact lens material. daysoft ® lenses with a Dk of 26 hit the bulls-eye.
