No optician has confirmed this belief but none have put forward
convincing arguments for the alternative and their livelihood depends on

I spend most of my time outdoors where the ability to focus close up is
not required. I don't suffer from headaches/eyestrain and carry reading
glasses on a neck string. Driving is more of a challenge as digital
dashboard displays are blurred but speedo is clear and automation takes
care of the rest.


Interesting view.

People who have one leg shorter than the other can end up with horrible
musculoskeletal issues because of the twisting induced. A simple heel
lift/raised shoe, obviously an aid, can prevent that.

Accepted.


I'd suggest that it is important to consider each and every one of the
aid options individually and not have blanket attitude.

The use of keyboard and mail has destroyed my handwriting as an example
of skills lost or diminished.

As for glasses and driving, I am shortsighted and can see the
dashboard, even the smallest details, well enough, without glasses. But
distance is another matter. I probably can pass the standard eyesight
test but why on earth would I question whether I need glasses day by
day, even minute by minute, depending on cloud cover? (Just went
horribly dark here.) Of course I wouldn't. Wear them and be done.

OK. Now try working outdoors when it is raining. Farmers flat caps have
a purpose beyond hiding their bald bits.

I like being able to tell the difference between a Rabbit and a Pigeon
at 300m.

But I purposely chose frameless with a cut-off at the bottom. Frameless
avoids any possibility of a frame getting in the way (even if it is not
a major issue for most people, most of the time). And the cut off means
I can see the dashboard underneath the lens which is easier on my eyes
than trying to focus through my glasses on something close.

I use a corrective lens for TV or deskwork. The next time an optician
advises a change I will consider frameless.
