There is a wide range of different visual impairments which, to a certain extent, are often not recognizable at all by an observer. Close relatives, work colleagues or friends cannot imagine some of the everyday difficulties faced by someone who is suffering from a visual impairment. However, there are many small things that will improve the lives of those affected, in particular, their level of independence and capacity to live and work with others.
Every visual impairment has its own individual characteristics and patients report a variety of symptoms: restricted visual field (tubular vision field), visual field loss, sensitivity to blinding light, nocturnal blindness, color blindness or general stark limitation of visual capability. Even among similar diagnoses, the effects can be very different from person to person.
