Health experts highlight signs of aging in vision and memory

As the global population of people over 60 is projected to nearly double from 12% to 22% between 2015 and 2050, health experts are highlighting the importance of monitoring age-related changes in vision and cognition.

Regarding visual health, specialists note that while decreased near-focusing ability and increased light sensitivity are common with age, progressive vision loss is not inevitable. Key conditions to monitor include cataracts, glaucoma, age-related macular degeneration, and retinal diseases linked to diabetes or hypertension. Cataracts, for instance, often present as painless, progressive blurring or difficulty seeing at night.

In terms of cognitive health, experts from Harvard Medical School distinguish between benign forgetfulness—such as misplacing keys or forgetting why one entered a room—and more serious symptoms. Medical consultation is advised if memory issues interfere with daily routines or are accompanied by disorientation or personality changes. Distinguishing between Alzheimer’s disease, which primarily affects recent memory, and other forms of dementia that may manifest through speech or mood alterations, is critical for accurate diagnosis.
