Problems with new glasses

[MrsAvocet]

I picked up a new pair of glasses a couple of days ago and have been getting headaches and nausea on and off since then. I've worn glasses all my life and have had varifocals for about 6 or 7 years now. These are my third or 4th pair of varifocals and I have never had any difficulty adapting before, so I am a bit unsure what to make of this. The prescription has been changed but the optician said it wasn't major. The change was mainly to my near vision prescription as I had been having to take my old glasses off to read, but my distance vision was pretty much the same as the last pair. I ordered the same brand of lenses with the same coatings etc as my old glasses and the frames are really light so I'd been hoping for increased comfort, not to feel so grotty.
Of course it's sod's law that its a Bank Holiday so I can't contact the optician til Tuesday! I can't decide whether to just swap back to my old glasses for now, or to persevere. I have heard people say that it takes them a while to adjust to new prescriptions, especially with varifocals, so it might just be that I suppose, even though its not happened to me before. If you've had anything like this, how long did it take before it subsided for you?

My friend took hers back. Turns out the optician messed up and the lenses werent done correctly.

Perhaps yours are the same. I’d take them back for them to check. I’d they are ok perhaps they made a mistake on the eye test?

Or perhaps it does take a while to adjust, although presumably you know what to expect from previous experience.

This sounds possibly like an issue with the lens as the measurements for the various focal points are incorrect and slightly out (there is only a very small margin of error) and so not allowing you to focus for far, intermediate and near vision as before. Is this a reglazing ie your existing frames with new lens? And are the lens specified identical to the previous lens in terms of grade, design shape and size of the different focal point corridors? I suspect either your frames need adjustment in how it sits naturally with more accurate three dimensional measurements as the frames sits on your nose bridge in relation to your eyes etc. I hope this makes some sense as I am not massively explaining it well (as just a long term glazes wearer). In any case if readjustment does not work then the lens is not correct for your eyes as even if the new prescription is correct the three focal points are not in the right spots on the lens for the frame as it sits on your face in the way you wear the glasses. You tend to know within seconds of trying your new prescription whether you can comfortably view far, intermediate and near vision. It can take a few minutes or even an hour but not days to adjust. It may also be that the optician has downgraded the quality of the lens and so a comparative smaller view corridors for near sight etc. This is noticeable if your previous lens had a much wider viewpoint. I hope this offers some assistance!

Here is the technical information though a bit too technical for non optometrists:

Thanks both.
They are new frames but very similar in shape to my old ones, just slightly bigger lenses. The brand and quality of the lens is the same as my previous ones. I think its something to fo woth the near vision component. There's no issues when I am say, out for a walk, but I start to feel a bit weird when I am doing close work. I think I will give the optician a call on Tuesday. My nose is also sore so I think the fit needs adjusting anyway. Disappointing, as they were not cheap and our optician is generally considered to be the best in the area. I know its where the local hospital ophthalmologists go for their own glasses. Ah well, I will see what they have to say next week. In the meanwhile I am back to taking my glasses off to read!
