I strongly agree with the spirit of his announcement, the metric system though great for science and engineering is all too often an abomination in ordinary non technical life. The avoirdupois system for weight in an everyday human scale is far more practical. Perhaps he's a product of Tony...

To explain my position on the proposed booster, the evidence in my area doesn't convince that the vaccines are anything like good enough. As mentioned a few times before, we have a very low vaccination rate which should mean suffering more from Covid, but it's the opposite, we continue to...

I'm also unhappy about this very real lack of information. My impression is that it's out of desperation to avoid a winter surge, without any evidence that it will succeed in doing that. As things stand I'm inclined towards refusing it. As you say, a new fully tested vaccine of proven...

These days I only ever see them if I deliberately call them up with eye movements beyond my norm. That could be due to having had them for so many years that I can't remember when they first appeared, It was certainly over 30 years ago, could be 40, plenty of time for the brain to perfect the...

This I can't guess at. From my own experience I'd say more like a month rather than a week for consistency, but we all vary so much from each other I doubt our personal experiences are valid for others. .

To show the extremes of compensation, my former extreme short sightedness of the right (dominant) eye from birth, the one I called microscope, measured before the second cataract operation at 6/36 metric. Yet I'd used that in combination with my left quite normally sighted eye all my life for...

As you said, it takes time. I had to live with my first very irritating floater for almost two months before the brain made if finally disappear in all normal circumstances. You probably know this, but cover the right eye and focus the left eye on something distant against a nearer edge...

Yes it can and does, for your unaided eyes. Add any artifical means and it becomes a different story of course. .

Yes, but it doesn't matter for the reason Danidl has given. Remember my posting that few peoples eyes are equal? The optical centre at the rear of the brain automatically compensates for such differences, intelligently interpreting what is happening and correcting for the differences...

I know what you mean. Since my ops my eyesight has been far better than when I was a teenager. Initially it is startling, but it's been a few years now for me so I now take it for granted. .

This reminded me of my brother's worst case NHS cataract procedure, he needed glasses for distance and another pair for reading. When his TV needed channels retuning due to a transmitter change he ended up stumped. He'd call up the menu from the remote using the close specs but then couldn't...

Seems like a good idea, though for most the contact lens routines would be just as much hassle as using reading glasses. My case was different from the outset since my eyes had always been markedly lopsided. So much so that I called my left eye telescope and my right eye microscope, so I had...

I don't have any other vision problem, it's simply the slightly greater delay in recovery from dazzle than it used to be. That isn't severe and I could still drive at night but I strongly believe safety comes first. It was the same with my cataracts, my optician insisting the worst eye wasn't...

This was already a problem for me in my late seventies since age brings night vision problems, our eyes as they age less able to cope with contrasts from light to dark. Today's high intensity LED street and headlamp lighting makes it even worse. With safety paramount at 85 now I no longer...

I'd also tried monovision with contact lenses very long ago during my working years, but like you I didn't like it, though with me that was more through the contact lenses than anything else. Too much trouble. Via the cataract surgery my monovision experience is very different and I'm...

We recently discussed NHS versus private for cataract surgery and you couldn't understand why I said private was better. I refrained from answering since my reply could have disrupted confidence in your treatment midstream, but now that's complete I can answer. I chose private since that...

Agreed, I don't think the BBC is routinely either of those, but I wouldn't be fool enough to believe they won't do the government's dirty work by broadcasting fake news when the government pushes them hard enough. They have a record of it and have openly admitted they did it long ago to help...

Not the BBC. This government goes into reverse as many times as a Yo-Yo, so whatever they announce, one only has to wait a day or so for it to become fake news! .

Radio 4 news announcement said Pfizer. That's why I posted about their rules intervals if 12 to 15s had two doses. .

That is what I posted, so not the opposite! .
