Reduced vision in adults can result from a focusing error, cataract or eye disease, but sometimes from a retinal problem or stroke. Gradually blurred vision needs investigation; sudden sight loss, flashes with a curtain or sight loss with neurological deficits is urgent.

  • Blurred vision at a distance, close up or at all distances, despite blinking or cleaning your glasses.
  • Straight lines appearing bent, a central patch in your vision or difficulty with faces and reading.
  • Use the right glasses and have a rapid prescription change or difference between eyes investigated.
  • Provide bright, even lighting and strong contrast for reading, cooking and using stairs.
  • Make an appointment for gradually worsening blurred vision, distorted lines, poorer night vision or more frequent collisions.
  • For urgent GP care outside office hours, call HAP 9252. Call Ambulance 912 only for an immediate threat to life.

Visual impairment and blindnessLow vision means sight remains limited even with ordinary glasses or treatment; blindness has different degrees. Causes and options vary greatly. Sudden loss of sight, a dark curtain, a painful red eye or loss of neurological function needs immediate assessment.

Reduced vision in childrenA child may see less well because of a focusing error, a lazy eye, a squint or an eye disease. Early checks matter because young brains are still learning to see. A white pupil, sudden sight loss, a painful red eye or serious eye injury is a warning sign.

Retinitis pigmentosaRetinitis pigmentosa is a group of inherited retinal conditions in which night vision and the peripheral visual field gradually decline. The rate varies greatly. Sudden flashes, many new floaters, a dark curtain or rapid loss of vision are not part of ordinary gradual RP and are eye emergencies.
