I am sure both are pretty bad, I have always wanted to donate my eyes when I die. I just feel claustrophobic thinking about people who can't see. It breaks me down literally. The person in a wheelchair has to face a lot too. I have a family member in wheelchair, so I know.
I won't say which is worse. Just can't compare. Only the suffering one would know.
I have severe health issues and as I always say to people,'I could be so much worse off!! At lesast I am not in a Wheelchair'. Now that you have posed this extremely difficult scenario to choose from,I think that the wheelchair would not be so bad when compared with having no sight!!! To not be able to see my family and my dogs,my flowers in the garden would truly fill me with sadness beyond description. And as a collector of antique ILLUSTRATED books,I would not be able to enjoy the visual magic of my beautiful past-time. So many things can still be achieved by people in wheelchairs,and more so than even a few years ago,with technology moving forward at such a great pace
As hard as being in a wheelchair might be, (and given my back condition that can't cope with too much sitting anyway) I'd kind of prefer this over being blind. I see a few people in my local area, some with guide dogs, some with canes, and marvel at how confidently they walk along the street to the shops, station, etc.
Being blind woukd be bad for me but also having relatives confined to wheelchairs can be just as bad, particularly when suffering loss of limbs. My grandfather was stone deaf and even having the large battery type hearing aid which meant the battery was carried in his top shirt pocket with a long cord to his ear, he told me he'd rather have lost a limb than his hearing so I guess each individual would have different thoughts for choosing their answer.
I know from having an uncle confined to a wheel chair from childhood that even in the 21st century that being in a wheelchair can still be difficult, but if i could never see the faces of my loving faměly again or a full moon or sunrise or sunset or anytjing, that would be very hard to cope with and adjust to.
Having neither disability I can only imagine. I would rather be confined to a wheelchair than to lose my sight. I am not a particularly active person and an active person might answer differently. I am an artist and could still work from a wheelchair. I am a very visual person.
