Bifocals specifically for sewing and telly?
My first varifocals allowed me to focus as close as 10cm but the area actually in focus at any short to medium distance was very small. Talking it through with the optician and explaining I needed to see a larger area at workbench / machine tool / screen distance resulted in a different prescription.
If it's been a few years since your last prescription you probably need an eye test anyway - you're not obliged to buy anything (other than paying for the test!) but it would enable a conversation with someone who knows what is possible.
MrE
I have long sight and astigmatism and varifocal specs with a strong prescription. My close vision has got much worse over the last few years. It's so bad I can't really do close work, e.g. sewing.
Should I get a new prescription in my varifocals, or a second pair of specs just for close work? Would specs for close work need a complex varifocal prescription, or could they just be ordinary OTC magnifiers? I don't want an optician trying to flog me hugely expensive new lenses which will be a compromise, and not good for sewing.
On the other hand, I want to be able to sew without changing specs when I look up at the telly.
