I'm 67 and have had bi-focals, progressives, and two pair of glasses with one for reading and one for distance. I've found progressives the easiest to use. I found two pairs of glasses totally impractical. Having to change glasses in the midst of things was stressful. And often I needed the reading pair when they were in another room or at home when I was away. Two pairs are a hassle.
I never got used to the lines in bi-focals. I found it easy to adapt to progressives and have been wearing them for 20 years or more.
I did choose to get only correction for distance in my sunglasses because of the expense and had to buy another pair because I couldn't read the car information on the dash with them. I bought progressives for my sun glasses too.
Which you choose depends greatly on how much correction you need. If you can still read, tho with effort, perhaps two pairs of glasses would work for you. However, I have a couple of friends who need only glasses for reading and they frequently don't have them with them and I have to read the menu for them. For me the choice is clear because I can't read without glasses. Progressives for sure.
