well, its better than "not that difficult", its already half done for us. with the existing supply chain, its already possible to buy glasses in most parts of the world (for whatever the price happens to be). this wont disappear with the overthrowal of capitalism. instead it can be appropriated to the needs of all, and improved upon. 

but its also more difficult than you let on. all this still requires coordination on a higher level, like building a medical schools with an ophthamology department, or like expanding access to areas where glasses were previously hard to get.
