I am very supportive of high activity for the elderly. This has a very positive effect on increasing life expectancy. I even read the results of a gender study in the Lancet. But there is a nuance. Older people should be supported both in their physical activity and in their vision. This will prevent accidental injury. There are wheelchairs that fold very easily. I even saw options for modern exoskeletons for the elderly)) But this is already exotic. As for vision, everything is much simpler. Older people know exactly their vision parameters and can order several options for glasses here. Modern medical laboratories support online fitting and online ordering for their clients.
