What? Cataracts?

So I have cataracts!  At just over 50! 
Most people get them in their late 60s and 70s, but I am one of the lucky ones to get them earlier.
About 2 years ago, I started noticing that my night vision was getting worse.  So I went back to my opthalmologist, who informed me that I had the start of cataracts.  He told me that the type of cataracts that I had were the kind that affect people even in their 20's and 30's.  He also warned me that this type of cataract usually progresses fairly quickly.
Well, he was right!  For the past 2 years, I have been having to get new glasses every 3-6 months.
Finally, on my last visit in February, he told me that I was now "medically qualified" for cataract surgery, which means that now my health insurance will pay for it!
So now I am looking at having the procedure done in April
