I wear tri focals and have never had a problem.Did you just get them and aren't used to them yet???

I learned a neat trick from this forum a few years ago for threading the sewing machine. Slide a piece of paper behind the needle. It helps to see the needle. I use white paper, unless using white thread.
Also, I bought a pair of tweezers from a hardware store. They are what I would call "reverse" tweezers. When you squeeze them, they open and when you let go they close. I use these to grab the thread after it makes it thru the needle. That way I don't accidentally pull the thread out of the needle.
BTW, I wear trifoclas too.

I saw a Sewing With Nancy episode where she said to paint the part of the pressure foot that is behind the needle white. She used a "white-out" type product from the office supply store.

There are self-threading needles available for your machine. See the link below.

Here is a link that might be useful: Self-threading needles

I found a few different devices for threading sewing machine needles:

Dritz Sewing Machine Needle Threader at Joann's

EZ-IN Sewing Machine Needle Threader

ZackIn Universal Needle Threader (which may not be available in the USA yet)

Thanks for all the good leads and suggestions. I deeply appreciate the help........Susan

If you still have problems after the suggestions you can do this. Thread your machine up to the needle. Pull extra thread to work with. Then remove the needle from the machine. Thread the needle making sure it is threaded in the right direction. Then Install threaded needle into machine.

When you wear bi or tri-focals, you move your eyes, not your head. I've worn tri's for the last nine years and bi about as long as before then. The opthomologist is the one that told me to move the eyes up or down to get to the lense you need.

A very helpful hint I read - to help with threading a needle, when you moisten your finger, instead of wetting the thread, wet the eye of the needle, either for hand stitching or machine. The needle grabs the thread and pulls it right in like magic! Less eye strain. Hope this helps.

I wear a contact in the left eye for up close work and I have the problem of difficulty threading so I bought myself a pair of reading glasses that I slip on (over the contact) and it magnifies enough to get the job done.....
