Refractive errors

A refractive error is the most common eye problem. When the shape of the eye is abnormal, the eye doesn't bend (or refract) light properly, and so vision is blurred.

The most common types of refractive errors are:

  • Long-sightedness (hypermetropia), causing blurred close and distance vision.
  • Short-sightedness (myopia) causing blurred long distance vision.
  • Astigmatism, which causes an uneven focus of light and blurred vision.
  • Presbyopia, which is most common with people over 40 years of age and makes close work difficult.

These errors can be corrected after being prescribed glasses or contact lenses. Surgery might also be an option.
