"I have taken Spiriva, more so in hot humid weather than in cooler weather, for 2 years and after 1 year did notice substantial difference in halos around lights especially driving at night, so much so, that I stopped driving at night.  Last eye exam in March of this year indicates I have cataracts.  I looked at full Spiriva Pharmaceutical description and in lab tests, this drug did cause cataracts in dogs.  So, now I am up for cataract surgery.  What does the FDA Protect?"
