At my last appointment, she said the change was so minimal during the last 5 years, that a new prescription was optional. Also, my cataract change was also so minimal, it would be years before something would be necessary.
So I paid the $30 (insurance covered the rest) and went happily on my way.
While I understand that eyes are precious and we should all see a real eye doctor at least every couple of years even if we don’t have vision problems, I am also a realist. I realize that people will not get glasses at all (and will drive half-blind) simply because of the prohibitive costs. So really, at least some of the people who use this service would not have had glaucoma or cataract screenings anyway. Also, it could provide a way for people whose insurance only covers every other year eye exams to update their eyeglass prescription every year if their vision deteriorates more rapidly than their insurance can keep up with.
Of course there are people who will use it to save a buck and therefore neglect very important aspects of their health, but I’m not into banning things just because some people will use them to worsen their own health (smoking, alcohol, junk food, large fountain cokes, etc.)
