Short-sightedness

Short-sightedness is not a disease but a vision disorder or, more scientifically, a refraction disorder. As such, short-sightedness has three “cousins”: far-sightedness, astigmatism and presbyopia.

Short-sightedness results from a defect in the ocular system: the eye is too long and the light rays meet in front of the retina, whereas they should normally focus on the retina.

In some case short-sightedness is accompanied by astigmatism.

What are the symptoms?

A person with short-sightedness sees blurred far away and clearly close up, but the problem disappears as he gets closer to the object.

Who is affected?

Short-sightedness affects more than 25% of the population and this percentage is increasing.

What are the causes?

In general, short-sightedness is hereditary.

However, certain external factors may also favour its development:

excessive use of the eyes close-up (reading, computer screen, …)
sleeping in rooms with little or no darkness, especially at a young age (night light)
excessive exposure to artificial light
an unbalanced diet with insufficient fibres, too much sugar and unsaturated fats
light pollution, such as street lamps or neon advertising signs

What is the evolution?

In general, short-sightedness develops between the age of 8 and 12 years, then it stabilises in adulthood.

How is it diagnosed?

Short-sightedness is diagnosed by a clinical examination by an ophthalmologist.

How can it be prevented?

Good reading habits have a beneficial effect on the development of short-sightedness:

read with good lighting
when reading for any length of time stop every half-an-hour to look into the distance
