Love seeing everyone jump in to help!
I would encourage you to allow your vision challenges to open up a new world of quilt options. Perhaps improv quilting or even improv curves. maybe applique that you can glue or iron in place first. start playing with different colors to see what works best for you. black and yellow tend to give higher contrast than black and white for folks with low vision. or you may find that a something else is easier to see. whole cloth quilting with contrasting thread could bypass piecing altogether.
I know everyone mentioned lighting, which of course is very very true. However, you may go a step further and determine what kind of light is best for you. One of my otto lights (or a knock off brand of otto, anyway), has the ability to change the warm/cool level.
most of all, find a way to continue enjoying your hobby!
