Aside from the gradual progressive loss of vision, can a person with RP seem to have better and worse vision at different times?
Yes, this is often the case. A number of factors might account for good days or bad days for someone with RP. For example, some people feel they see better on cloudy days; others feel they do not see as well on cloudy days. Fatigue and emotional stress may also temporarily affect vision. People who have RP report that it often takes a lot of effort to see and that the emotional and physical effort is exhausting and makes one feel as if they don’t see as well when they are tired. However, none of these circumstances seem to affect the progression of RP.
