Elderly individuals aged 75+ often have poor uncorrected vision but achieve good corrected vision with spectacles. Most could read N8 typesize, indicating vision improvement with aids.

Area of Science:

  • Ophthalmology
  • Gerontology
  • Public Health

Background:

  • Age-related vision decline is a significant concern for the elderly population.
  • Understanding visual acuity in older adults is crucial for maintaining independence and quality of life.

Purpose of the Study:

  • To assess the visual acuity of elderly individuals aged 75 and older in Melton Mowbray.
  • To determine the effectiveness of corrective lenses in improving vision for this demographic.

Main Methods:

  • A two-year study was conducted involving elderly residents of Melton Mowbray.
  • Visual acuity was measured using Snellen charts (uncorrected and corrected).
  • Reading performance was assessed using N8 typesize under test conditions.

Main Results:

  • Typically, individuals aged 75+ exhibited poor uncorrected vision (6/36 Snellen acuity).
  • A significant majority (73.8%) achieved 6/12 binocular Snellen acuity or better with correction.
  • Over 88% could read N8 typesize or better when tested with corrective measures.
  • Poor uncorrected vision correlated with spectacle use.

Conclusions:

  • Corrective lenses are highly effective in improving visual acuity for the elderly population (75+).
  • Spectacle use is prevalent among those with poorer uncorrected vision.
  • Maintaining good corrected vision is achievable for most elderly individuals, supporting their daily functioning.
