      • Decrease in distance vision, difficulty with night driving, monocular diplopia and loss of color discrimination ability
    • Signs:
      • Gradual opacification of the central portion of the lens nucleus
      • Age-related, involves the hardening (sclerosis) and either yellowing or brown to black darkening (brunescense) of the lens nucleus
  • Management: when the reduction in visual function associated with the cataract interferes with daily activities, cataract surgery may be considered.
