JohnR: I hope that the NHS give you the same choice of lenses as we can get for cameras. A nice macro in one eye and a wide angle in the other?
Sounds good but doesn’t quite work like that. Because of my problem, my left eye is now short sighted and the short sight is getting worse quite quickly (I am reassured that this is normal with some cataracts). My right eye is long sighted and with not many other problems with that eye I won’t need new hardware for some time. You would think that the combination of one eyed short sight (macro) and the other long could be advantageous. Sadly, that's not the case.
However, (technical this) the difference in glasses prescription required is such that when the bad eye worsens beyond a certain point, my brain won’t be able to cope with the confusing image sizes from the eyes. Result - I will get double vision sooner rather than later. I suppose that might mean seeing two Grizzled Skippers or two Swallowtails or two of everything. Trouble is, I wouldn’t be able to drive anywhere to go and see them. So new hardware being installed in January and things should have settled in time for the new butterfly season.
We all live too long nowadays (I’m not of course complaining!). In the old days, you would have keeled over long before problems like this showed up. I liken modern medicine as being akin to keeping that old Moggy Minor on the road.
