I wear bifocal, multi-focus prescription eye glasses. The top is for long range, and the bottoms allow me to tilt my head a bit to bring nearby objects into focus.
Finding sunglasses that clip-on, or fit over my prescription glasses is difficult, there are usually no or only a limited selection. There are also many trade offs with clip-on or fit over sunglasses.
I am considering getting prescription sunglasses, but have no idea what to look for. I know there are some that change automatically from sunglasses to plain vision, but that is about all I know.
My outdoor life is fairly active, often with many hours spent on the water and driving in all conditions. I drive through a tunnel almost everyday (it is well lighted, with an average transit time of about 1 minute)
My indoor life, involves looking at a computer screen for 8 hours a weekday, a bit of TV watching and operating power tools indoors and outdoors.
We have an existing question Things to consider when buying sunglasses that has some good information but it is specific to non-prescription.
I like the idea of glasses that change from sunglasses to indoor. Cost is not a significant consideration, performance and ease of use are the driving factors in my choice.
