...does anyone else have the following problem. Basically I am starting to get on a bit, and cannot focus on objects nearer than about 6 inches away, it is further with my glasses on...
Unfortunately, I'm afraid the answer is just about
everyone who is getting on a bit!
As you yourself stated, it is due to the lens being no longer able to change shape to accommodate focussing at different distances.
There are, however, several options as well as those already mentioned. When I wore contact lenses (for distance vision) I also wore 'half moon' reading glasses which made it convenient to look up for distance vision and look down for near vision. I now wear varifocals for the same reason, although bifocals are a cheaper alternative.
It is even possible to buy 'bifocal' contact lenses which do exactly the same: when looking straight ahead, you look through the centre (distance) part of the lens; when you look down, the lens rests on the lower eyelid and your vision is then through the outer part of the lens that is corrected for near vision. I'm sure your optician would be happy to take your money for a pair!
I understand that should your lenses ever 'cloud up' due to cataracts, it is now possible to replace the lenses with artificial ones that are sufficiently pliable to be deformed by your eye muscles for close vision, just as your more youthful (!) natural lenses were. I believe that they would have to be done privately, though, at great expense!
