yeah, but that's how he feels. Right now at least. There's more to it than that, and to find out what that is and to begin to fix it, that will take a lot more communication and work on both their parts.
The reality of the situation needs to be worked around how he feels (and how she feels) until he accepts again that she will need more help due to her eyesight issue and realizes again how much she does contribute. Sometimes people get busy and caught up in all that they are doing that they lose sight of how much their partner contributes. This can be especially true in a case where their partner has needs that makes them more dependent on their partner's help.
