I can see clearly now

After receiving my long and eagerly awaited text first thing this morning, I went into town to pick up my new varifocal contact lenses. Unfortunately, they're not the real thing yet. They're sort of learner lenses, to see if my brain can get used to processing the image correctly, or at least in such a way that I can function normally. I'm told I will have to try these out for a week, and then they'll test and tweak them some more until they're absolutely fine. As I've already noticed that these are a little bit weak, this'll probably mean another two-week wait for my very bespoke new contacts to arrive...But! I'm already much happier with these than I was with the set they'd sold me earlier, that allowed me 20-20 vision at 50 mtrs distance, but were completely useless when it came to reading a book or off a computer screen. Now I can read the instructions on the packet again, and you don't know how happy that makes me!

The funny thing with these contacts is that (on the face of it) they don't look any different from normal lenses. Whereas with varibifocal glasses you usually see a divide between the bit used for looking into the distance and the bit needed for reading, the surface of these lenses is completely smooth -- and you don't have to worry about putting them in at a specific angle or anything. The secret, I'm told, is in the way they're crafted; with the centre optimised for distance-viewing, and the edges for close-ups. The result is that you're constantly getting two images that the brain has to meld into one; which I'm relieved to say seems to be working perfectly in my case, and I don't see why I should wait another week before we can do another check to see if I take to them. But the optician was adamant I needed to give it all this time, and so I shall. Reluctantly.

Actually with varifocal glasses you can't see a divide. You can on bi and trifocals. I'm rather jealous. I can't wear varifocal contacts partly because of astigmatism and partly because I'm just too short sighted so I have my contacts optimised for distance and have to wear reading glasses for close up stuff. I tried having one eye optimised for long and one for short but it really didn't work and it was affecting my refereeing.

I stand corrected! I guess I just never got the difference between the various focals available before ;-)

As someone who has one long and one short sighted eye (though I expect age to correct this at some point), I find I have real trouble with depth perception and am clumsy most of the time. Glasses don't seem to help much though, perhaps it's just me blaming the eyesight. :(

Coincidentally, my new glasses came in today. If the snow stops, I may go and get them. Or I may wait for the city to dig out and go Monday. I really want them, but I don't want to slog through snow and slush.

I envy you the ability to wear contacts. Not part of the Jonesie package. Hope you adapt to the varied foci.

(We call varifocals "progressives" in these parts. The lens "progresses" from distance vision at the top, middle distance at the centre - for computer use, seeing the dashboard in your car, conversing comfortably with someone across the table - and reading at the bottom. And thank goodness there's no line as your earlier responder said. I'm geeky enough with my Einstein do).

I envy you the ability to wear glasses. They're so much less hassle than contacts (which I always seem to lose).

Oh I am glad that you haven't got to line them up in any particular way these days, like S2C had to with his contacts when he had them.

As the others have said, we really don't have lines on our glasses these days - I'm not even sure if they still make old-fashioned bifocals any more.

My mum still wears the bifocals with the visible line on them...but God knows when she last got a new pair.

Glad that your lenses are working out. :)

I'm steadfastly resisting updating my glasses prescription as I believe catering to the weakness in sight makes it worse. This may or may not be true, but it saves me money on glasses!!

I can't tell you what a relief it was this morning to pick up a paper and be able to distinguish individual letters again! I then went and bought a couple of books to celebrate.

I keep telling myself I'll get varifocal contact lenses when my eyesight fails. I've got "normal" contacts now and don't need anything stronger yet. So I'm glad to hear from someone who's tried varifocal ones and liked them. Can't imagine going back to wearing glasses, even though I haven't worn them much over the years.

Re: Contacts
I've had these varifocal contacts for two days now and thankfully haven't had any problems adjusting to them, though the optician did warn me that they're not for everyone. I don't know what I would have done if I had been among the number of people who for one reason or another can't get used to them, though I have heard there is a common workaround that involves going back to 80% of the strength needed for perfect long distance viewing.
