A meta-analysis of 29 studies involving 7,090 nursing home residents found visual impairment in 46.4% before vision correction and 24.3% after best correction. Cataracts were the most common eye condition, affecting 55.6% of residents, and researchers recommend more regular eye care in long-term care facilities.
A review of 29 studies involving 7,090 nursing home residents found that 46.4% had visual impairment before vision correction, while cataracts affected 55.6% of residents and were the most common eye condition. Published in the Journal of the College of Optometrists, the meta-analysis also found lower rates of impairment and blindness when vision was measured after correction, pointing to a potential role for access to eye examinations and appropriate treatment.
The review compared residents’ presenting visual acuity—vision as measured before correction—with acuity after best correction. Visual impairment prevalence was 46.4% before correction and 24.3% after best-corrected vision. Blindness affected 8.7% based on presenting acuity, compared with 3.9% after correction. These are separate measurements; the difference does not establish that every case can be corrected.
Cataracts were reported in 55.6% of residents, followed by refractive errors at 39.8%, age-related macular degeneration at 21.4%, glaucoma at 13.9% and diabetic retinopathy at 7.7%. The analysis identified cataracts as the leading preventable cause of vision loss across the regions examined.
According to the report in Skilled Nursing News, most studies in the review found significant improvement in visual acuity after refractive correction. The researchers recommend routine comprehensive examinations, access to free or subsidized glasses, timely referrals for cataract surgery and nutritional interventions. They also recommend an examination before nursing home admission, followed by annual examinations or evaluations.
Eye Care Gaps in Nursing Homes
The findings matter because vision problems can affect residents’ daily activities and ability to communicate, while some impairment may be addressed with corrective lenses or clinical care. The review’s lower prevalence figures after best correction suggest that measuring vision only as residents experience it may include problems that improve when correction is provided. The study does not, however, show how much of the difference resulted from glasses, surgery or other care.
Residents may face barriers to getting care. The researchers cited advanced age, frailty, multiple health conditions and cognitive impairment as factors that can make it harder to reach eye-care services, describe vision concerns or receive treatment. For nursing home operators and care teams, the recommendations point to service arrangements that bring examinations, eyewear and referrals within reach of residents.
The results are prevalence estimates drawn from multiple studies, not proof that a particular intervention will produce the same outcome at every facility. Still, the gap between presenting and corrected vision supports the case for identifying and addressing vision problems rather than assuming they are an unavoidable part of aging.

How the Review Measured Vision
The Journal of the College of Optometrists analysis examined published studies from multiple regions to estimate the prevalence of visual impairment, blindness and common eye diseases among people living in nursing homes. Its combined sample included 7,090 participants across 29 studies. The figures summarize those studies rather than results from a single facility or a new examination of all nursing home residents.
The distinction between presenting and best-corrected vision is central to interpreting the results. Presenting acuity reflects vision before correction is applied; best-corrected acuity reflects vision after correction. The report says most of the included studies found significant acuity improvements following refractive correction. It describes cataracts as the leading preventable cause of vision loss, while also listing other conditions, including macular degeneration and glaucoma, among residents.
“Factors such as advanced age, frailty, multiple health conditions and cognitive impairment may make it more difficult for residents to access eye care, communicate vision concerns and receive appropriate treatment.”

Limits of the Prevalence Estimates
The supplied report does not give the review’s full methods, the dates covered by the studies, or a breakdown of results by country, facility type or resident characteristics. It is therefore unclear how evenly the findings apply across nursing homes and health systems. The pooled figures should not be read as a count of all residents or as a current census.
The difference between presenting and best-corrected vision also does not establish which residents received new glasses, underwent surgery or had another intervention. The source does not quantify how many cases of impairment could be prevented or treated, or whether recommended services would change outcomes across facilities. The review describes cataracts as the leading preventable cause, but the material provided does not specify how that classification was determined for each resident.
Routine Examinations and Referrals
The researchers call for nursing homes to expand access to comprehensive eye examinations, updated prescriptions and affordable eyewear, with timely referral for cataract surgery when appropriate. They also recommend an examination before admission and annual follow-up. The source material does not identify a policy deadline, implementation plan or funding commitment tied to these proposals.
The next practical step for facilities would be deciding how to arrange examinations and referrals for residents who may have difficulty expressing vision concerns or traveling to outside services. Whether providers or policymakers adopt the recommendations, and how much they improve access or vision outcomes, remains to be seen.
Key Questions
What share of nursing home residents had visual impairment?
The meta-analysis estimated 46.4% before vision correction and 24.3% after best-corrected vision, based on the studies included in the review.
How common were cataracts among residents?
Cataracts affected an estimated 55.6% of residents in the analysis, making them the most prevalent eye condition reported.
Did the review find that correction improved vision?
The report says most studies found significant improvement in visual acuity after refractive correction. The pooled figures were lower after best correction, but they do not show that all impairment can be corrected or identify which treatments accounted for the change.
What eye-care steps did the researchers recommend?
They recommended comprehensive examinations before nursing home admission and annual follow-up, access to free or subsidized glasses, timely cataract-surgery referrals and nutritional interventions to support eye health.
