How many galaxies/stars do we visually lose every year due to them accelerating and passing through the cosmological event horizon?

I was reading about dark energy on Wikipedia and this question had me pondering on a bit.


edit: 

Hello everyone, I appreciate all the feedback received from this post and I'm grateful for such well presented answers. I realise that this sort of question can raise many different answers due to the question being too general. 

But as I understand from most of the replies... The reason the light from those stars will never entirely vanish is because even when the star/galaxy passes the cosmological event horizon, the space between us and them is only expanding and so the light that was sent before the star/galaxy passing the cosmological event horizon will only stretch due to the expansion and continue to reach us but through other spectrums of light as it continues to redshift. Would this be correct? 

I would also like to bring forward a question that has been brought up by a few other redditors. However as it may seem there is no exact answer to it, I'd like to ask a question similar to it:

Which stars/galaxies have most noticeably redshifted or faded from visual light? I'd definitely like to read up on this topic so any names or articles would be great. Thanks again guys!

We don't visually lose them. The light that they emit now will never reach us, but the light they emitted before will take longer and longer to reach us, so they'll just gradually get dimmer and more redshifted, but never completely disappear.
