I'm severely visually impaired/leglly blind. I have an even condition that means when I'm outside in the sun it very difficult. Therefore I wear glasses that get dimmer, so they're like sunglasses. I don't use glssses for anything else as they make no difference to my vision. I'm at high isk of developing glaucoma so I have to say I'm pretty lucky to have some remaining and my disability has definitely made me a much stronger and resilient person - it's basically one thing that has helped me create my personality.
