Hi! Thanks for your reply! You can be developing calcium deposits for a variety of reasons.
Do you use a cleaning eye drop through out the day? I find Naphcon A and No Rub Multi-Purpose Solution (<- personal favorite when I cant see) work great.
Most obvious would be the lens. Have your tried a different brand, or type of lens? This is the most common problem people have. Extended wear lens tend to help resolve this problem or atleast reduce the frequency.
Secondly, have you had your eyes checked for any infections? I have provided a link for information about the cornea, and some common problems that could cause similar problems.
I hope this helps.
