58% PHEMA, 42% water. Thus, the composition of the lenses according to the supplied piece of paper. The whole thing is a silicone hydrogel, as it is known by the normal soft monthly lenses whose material ends in "-filcon" (For example Narafilcon). It also function all normal silicone hydrogel hygiene solutions for inserting the lens, if the supplied vial should be empty times.
So far so good. The lens wears very very pleasant and looks perfect for that I must lose no words. At this point, short nor for shipping and payment All the best :).
The point where now but is unclear to what extent the lens of normal lenses is different, is this: you will not find any information of the oxygen permeability or the thickness of the lens, so the indication of Dk / t value. And at that point the whole is NEN bit critical with these lenses, because if the DK / t value 'is bad', so the oxygen permeability is low, then it may be that during longer periods and regular visible formation of veins in the eye takes place ,
The results from an inadequate supply of oxygen from the air, which normally reaches the cornea of the eye. The lens blocks the then but from the eye and thus refers to oxygen from the blood to tissue necrosis by "choking" to prevent this blood passes in turn logically through the vessels, so the veins, to the appropriate place. And because hardly anyone fat veins in this area has in mind, so this must be reformed; > Neovascularization
For me, I had been absolutely no problems and carry them even in everyday life when I feel like it. So those are probably the cheapest and best lenses you can get strong buy recommendation. And I've really looked around a lot :)
PS: I have the 14.2mm lenses 15mm already very very big and I put it value that you look at me the lenses immediately. So in doubt take the small (Also, where less surface of the eye covered, ergo: More oxygen for the eye and less neovascularization hahaha: D)
Best regards
