Cranky rant on Pharma and presbyopia eye drops

I took an interest in pilocarpine (Vuity TM) eyedrops because, like, well, everyone my age, I have a bit of presbyopia (age related failure to focus on near detail). But the hell with it. They got a patent on a formulation and use of a drug that's been around since the 19th century and thanks to our excessive patent laws can prevent anyone else from selling this drug for this purpose. So they have a license to charge $80 to $100 for a tiny quantity that I'd be willing to bet costs significantly less than $5, including packaging and distribution, to produce. And since it's not considered "medically necessary," (it's only seeing after all, not really essential to survival), it's not covered by most insurance in this country. 

And people wonder why Pharma is one of the most resented, even hated, commercial sectors of the economy. "Systemic gouging" like this is the reason. 

I've already decided to do without. My $10 reading glasses work just fine.
