Cataract: Symptoms

The main symptom of cataracts is progressive vision loss, which usually begins in the 60s.

Cataract usually affects both eyes in a nearly symmetrical fashion.

A person with cataracts suffers at the beginning of his illness:

  • a drop in vision from a distance,
  • photophobia (discomfort to light),
  • poor night vision.

In addition to these visual symptoms, the person may tend to see double ...

Gradually, the vision gets worse and becomes blurred permanently. The individual finds himself permanently as in the fog. And the colors are, consequently, no longer as contrasted.

Another characteristic symptom is photophobia. The person is easily dazzled by the light. In the long term, the opacification of the crystalline lens can be almost total and only allows light perceptions to show through.

When you look at the pupil of a person with cataracts, it is opalescent. It is actually the crystalline lens that we see, abnormally opaque. Normally, its transparency allows you to see the back of the eye, black.

The diagnosis is based on the measurement of visual acuity with an ophthalmologist. In case of visual impairment, examination after pupillary dilation allows to find the opacification of the crystalline lens, to locate it and to characterize it on a biological level.
