Progressive Lenses vs Trifocals vs Bifocals for Woodworking
I wear polycarbonate bifocals set for arms length/computer focus and distance on top. For 20 years now I see best from 6" to 14" with no glasses so I take them off in the shop a lot. It's a lot of off and on and I have no protection without glasses on. I'm thinking trifocals may be best for me.
I have trouble reading labels over a store countertop lately. Do trifocals give you clear focus from 6' out to 10'?
In another thread people report no straight lines thru progressive lenses.
What type of lenses work best for you ?
Different people can have different point of view

I only started to need glasses from my 46 and since then I had to adjust to my "new condition". A few years later I defined my policy towards glasses:
- For some activities, each time less and less, I do not need glasses, so I don't use them
- I have a single fixed focal glasses for reading (I think they are focused at around 30 cm)
- I also have a dedicated single focal glasses for computer use as I have a big screen in my home workstation (these one is focused at around 60 cm)
- For most activities I use my multi continuous focal (progressive?) glasses. including to use laptop, drive and work at workshop
I am comfortable with these three glasses but I do not believe it is the best solution for all. My mother, as an example, prefers to use a single pair of glasses for all... each one at his/her own.
