Same here. Need more powerful ones for reading, though.

I also require glasses for reading small print (moderate
long-sightedness - +2.5D glasses). I really dislike wearing them
because apart from making the print clearer, they also magnify it. I
can't get my head round whether or not this is solely a consequence
of the lenses correcting the long-sightedness being convex, or it's
something else. Why is it not possible to correct the focal
deficiency without magnification?

As an aside, does anyone else feel that an eye-test where you are
asked if different lenses are clearer or not isn't very scientific?

There isnt any other way to do it.

There is - an Autorefractor.

It doesnt replace what he doesnt like.

Fair enough.
