I have occupational lenses, similar to those described by Chestnut. They are a type of varifocal. They are the best lenses I’ve ever had. They’re not designed for wearing out of doors, but I always wear dark glasses outside as I can’t see in bright, or even not so bright, daylight. My dark glasses are varifocals so are very handy when shopping. I change my glasses when I’m leaving the house and when I return. Much better than having to carry more than one pair of glasses. Some varifocals have a wider field of view than others. Get the widest field you can at a price you can afford. My current glasses cost an arm and a leg, but they have improved my poor vision tremendously. Varifocals can now be made with much thinner, lighter lenses than was once possible so you don’t need thick heavy frames, unless you want them of course.
