I have what is called "progressive lenses" They are basically invisible line bifocals that cover everything "near, far and in-between." I also just bout an adjustable bright light that sticks on the machine. It will focus the light EXACTLTY where you need it. I have sewed with Ott Lites for years and this teeny light was only about $30. including shipping. Might be an option to consider.

Proper lighting is a must. Not good light, great bright light that you can't get with a regular light bulb. I use Ott lights over my machine and my machine is in front of a double window. I try to do all my machine sewing when the sun is coming through the windows. It makes a big difference. I can't tolerate dark rooms when I'm awake. I have to have sunlight or bright lights on all the time. I have 23 light bulbs in my living room with two bright flood lights over the fireplace and that's just one room. My sewing room is just as well lit. I think good bright light makes everyone feel better.

Change in eye glasses? Yes! I was so afraid to go in, my eyes were really getting bad. Not on the close up stuff, but at a distance, oh my! Turns out that as you age your vision, at a distance, is that near sightedness, gets better! I went to a weaker eye glass and I was cured!

bring on the aging then!

My eyes really bother me after a day at the machine. Blanket stitches really do me in; I can only work for 1/2hr if I'm doing that or any other special stitches.

I don't think that quilting causes a change in your vision, but it may make you more aware of a problem that needs attention.

Wow! Hope this is what it is. Have my Dr. appt for next Thursday.

I have trifocals for the computer. one lens to see the keyboard and the other the screen.

With my first, and only at this time, FMQ project my shoulders, elbows, neck and forearmes were sore for several days. I get so caught is what I am doing that time means nothing! :roll:

I keep a very strong pair of readers, from the dollar store, at my machine because close up work is difficult to do with the reading 'prism' in my right lens. I even wear them for computer work if my eyes begin to get tired. (I have glaucoma, so that could be part of the problem.)
