3 Reasons Why This Will Be Your Favourite Contact Lens, and 1 Why You’ll Hate It

/in , /by

Let’s start with the good – 3 Reasons why you’ll love this contact lens:

  1. 156.  What does 156 mean?  Well the Dk/t of course!  Dk/t is the measurement of oxygen permeability of the contact lens and the higher the number the more permeable the lens is to oxygen.  And for the cornea, which has no blood vessels and breaths directly from the air, the higher the Dk/t the better.  There is only one contact lens that has a higher Dk/t than this lens, so that means your cornea will love this lens.
  2. Protein.  If you are on the Aitkens Diet protein is good, but when it comes to contacts protein is bad.  Proteins stick to contact lenses after just one wear and they can’t be completely removed with cleaning.  Proteins will cause decreased oxygen permeability, increased dryness,  a rough surface on which bacterial biofilms can grow and cause inflammation that can lead to red eyes and contact lens intolerance.  More and more studies show that the best way to combat protein is with a daily disposable contact lens, like this one.
  3. Lubricity.  The thing that makes contact lenses uncomfortable is friction.  Friction between the lids, cornea and contact lens.  A lens with less friction, or lubricious, will be more comfortable.  This lens is designed to be so lubricious that 4 out of 5 wearers say it feels like they are wearing nothing at all.  Check out this video comparing the lubricity of contact lenses.

So with all this good what is to hate?

  1. If you are hyperopic/farsighted, need a bifocal or require a toric lens for astigmatism it is not available in your prescription – yet.  Then again, you might just be willing to have a little blurriness to wear this lens.
