Future research may gain further by assessing even more specific aspects
of visual function objectively (e.g., impairment in depth perception, extreme contrast or brightness sensitivity in addition to visual acuity as assessed in NSHAP) and subjectively (e.g., self - reported
trouble with reading newspaper print and recognizing people at a small distance in addition to the global assessment
of one's vision as assessed in NSHAP) in the study
of the effects
of vision on
quality of life and the capacity
of a good
marriage to alter these effects.
