Decreased visual acuity in particular was associated with recall difficulties in a study of US and Chinese populations.

Previous studies have explored the link between vision and cognitive
loss, as the number of people with dementia worldwide increases each year due to
a growing elderly population. However, the results were limited and did not focus on different backgrounds and nationalities, so researchers recently looked at whether vision impairment and eye diseases
acted as "predictors" of memory loss. They simultaneously studied patients in China and the United States, using data from representative population-based samples from each country.

The Chinese data set included 8,315 participants and the US group included 8,939. All were aged 50 and over. During a four-year follow-up, the researchers found that impaired distance vision
was associated with greater memory decline in both China and the United States. History of cataract or glaucoma surgery did not affect the results in either group.

"The magnitude of the inverse association between vision and change in memory was greater in the United States than in China," possibly due to the older age of the U.S. participants resulting in greater memory loss, the researchers wrote in their publication. ​

"Our analysis showed that people with farsightedness were more likely to have lower education and a higher prevalence of psychiatric disorders, diabetes and hypertension which are known risk factors for dementia." Adjusting for these factors did not substantially change the relationship between distance vision impairment and change in memory, finding that "potential effects of vision impairment on memory decline may be mediated through other pathways."

Researchers suggest that screening vision in older adults may help prevent or delay memory loss and the development of dementia.
