I don't know. Cataracts and macular degeneration both affect vision and are associated with aging. But whether they both are related to stress and damage created by an eating disorder is something I don't know. You'd have to check with an ophthalmologist to see if there is current research available. Whether they are related or not, you can be sure you are in a better situation to have healthy eyes if your body gets the nourishment it needs and doesn't have to go through the stress of purging A problem with eating disorder thinking is that the concern is for the immediate. Consideration of the long term is lacking. The idea of actual being mature, then senior then really old doesn't have impact on decision making or even feel like a real consideration. Yet, we all age until we die. And as we age, we are still who we are, feeling, thinking and caring about what is important to us. We talk on this site about being kind, protective and respectful to the child we were. We need to learn to be kind to ourselves now out of respect and caring for who we are in the moment and in the far future when we are seniors. Agree?
