Bazile, you have set yourself up for a regular post. I'll look forward to tomorrow's :o)

I expect I've seen articles about it but was too poorly-sighted to be able to read them properly.

Hopkirk, I think you will find that geogriesmum whilst registered blind still has some sight and is able to see a PC monitor, maybe with certain programmes to help as was the case with my Mother (RIP.)

[Hopkirk]

Ah, thanks Ratter.

When we were younger, we always thought that twisting the cone would make the lights change quicker! I didn't realise what the device actually had such an important use.

I didn't know this either. Thanks for sharing this tip, not that I need it, but, you never know...

I did know that Baz because my late husband was reg blind.

I didn't know that. Thanks for posting it. I know a blind chap and I'll make sure he is aware of it.
