I read that certain kinds of contact lenses--silicone hydrogel, to be specific--can "attract dirt" that could lead to an eye infection.
First of all, what kind of "dirt" might cause an eye infection. I doubt if many people get actual soil from the ground in their eyes.
Secondly, do silicone hydrogel contact lenses actually "attract" that stuff? In other words, does wearing silicone hydrogel contacts increase the likelihood that "dirt" will get in your eyes?
