Causes of sight loss
Some people are born with reduced sight whilst others may acquire an eye condition later in life, such as retinitis pigmentosa that deteriorates with age. Others may lose their sight in an accident, or because of a disease like diabetes or arthritis.
Age-related eye conditions are the most common cause of sight loss in Europe. Eyesight in seniors may be affected by conditions such as macular degeneration or cataracts.In the poorer countries of the world millions of people suffer sight loss caused by preventable diseases. These types of vision loss are called ‘preventable blindness'.
More information is available in the publications section.
The definitions of blindness and partial sight, as well as the registration criteria vary from one European country to another.
EBU adopts in principle the definitions used by the World Health Organisation (WHO) for blindness and partial sight. At the same time EBU advocates the importance of using the so called 'functional sight' parameters in addition to the WHO definitions when determining the support a blind or partially sighted person needs.
The term ‘visual impaired' is used to indicate blind plus partially sighted people together.
Partially sighted and low vision are used as equal indication of limited sight.
Other criteria generally used by ophtalmologists:
- A person can register as blind if they can only read the top letter of the optician's eye chart from three metres or less.
- A person can register as partially sighted if they can only read the top letter of the chart from six metres or less.
Living with sight loss
People with sight loss are from all walks of life, have different backgrounds, education and social status. The way in which each individual is affected, is highly unique and can be a totally difference experience from one person to the other. Support, rehabilitation, social benefit system are some of the factors that make coping with sight loss easier.A common misconception is that blind persons cannot see anything at all. This is of course true for some, while many have some perception of light and shadow, see everything in a vague blur, have tunnel vision, or lack central vision. There are many different eye conditions and they all produce a different form of vision distortion.
