Q:Oxygen Permeability (Dk Value) of Daily Disposables
I'd been wondering when you could what is different Dk values for ones daily disposables choice of disposable lenses? I've tried the silicon hydrogel ones before on the basis they've already a higher Dk value, but I stumbled upon which they didn't supply clear vision…the most beneficial form of lens I have found for clarity is Nelfilcon A.
's the reason because of this difference in clarity because of the oxygen permeability? Can there be a lens with good permeability and good clarity?

A:Good clarity with contact lenses is afflicted with a full number of factors. Lens design, permeability, hydration chracteristics are a few of the standards. Silicon lenses are good for the fitness of a persons vision, but are often much less at ease with normal hydrogels. Chance to find the trying different kinds before you find a very good for you. Your optician should have the Dk values for virtually any lenses which they suggest in your case.
