A recent analysis found a link between vision loss and higher risk of dementia. The results suggest improving visual acuity, such as with eyeglasses or cataract removal, might help maintain cognitive fitness in older adults.

Most people have eye twitches at some point in their lives. These are usually a sign of minor physical or mental stress. Spasms can be calmed with a warm compress, sleep, or exercise. People should see a doctor if one or both eyes close involuntarily with spasms.

While not as routine as cataract surgery, corneal transplants are becoming more common. A number of things can go wrong with the cornea, especially as people get older, and a partial-thickness or full-thickness transplant can restore vision.

Vigorous exercise may improve dry, itchy eyes by boosting tear production and quality.

A 2021 study found that people who underwent cataract surgery (a procedure replace the lens of the eye) appeared to have a lower risk of developing dementia than those who had cataracts but did not undergo surgery.

An observational study published online Dec. 6, 2021, by JAMA Internal Medicine found that the risk of developing dementia was 29% lower in people who underwent cataract removal, compared with people who didn't have cataracts removed.

A reduction in tear production can lead to a condition called dry eye syndrome. It causes the eyes to become dry and irritated and may be prompted by aging, medication, or hormone shifts. Eye drops and ointments can help relieve symptoms.

Having surgery to remove cataracts restores blurred or distorted vision, helping to improve quality of life for older adults. Now, a new study makes a strong case that removing cataracts may reduce a person's risk of developing dementia.

Many factors can impair balance and lead to falls, such as vision, hearing, or joint problems; medication side effects; and environmental hazards. To improve balance and reduce the risk for falls, one can remove fall hazards from the home, treat underlying conditions that increase fall risk, consider adjusting medications that affect balance, get physical therapy, use an assistive walking device, wear supportive shoes that hold the feet in place, and frequently challenge balance with balance exercises.

People who get age-related macular degeneration, cataracts, and diabetes-related eye disease may have a higher risk for dementia. Having more than one eye condition may further increase the risk.
