Instruction
In this topic you will learn about vision and different vision problems that people may experience.
What is vision?
Vision is the ability to see. This includes being able to see up close and in the distance.
Visión de lejos
La visión de lejos es la capacidad para ver con claridad objetos que están a distancia.
Utilizamos la visión de lejos para ver (por ejemplo):
- La pizarra en un aula
- Carteles que indican nombres de calles o de comercios
- Faces across a room.
Visión de cerca
Near vision is the ability to see objects up close.
Utilizamos la visión de cerca para tareas como:
- Leer libros o periódicos
- Coser
- Preparar la comida
- Sorting objects.
Problemas de visión
Una persona puede tener distintos tipos de problemas con su visión, entre ellos:
- Distance vision problems
- Near vision problems
- Eye health problems (for example, infections and cataracts).
A person can have one or a combination of these, and to different levels of severity.
Most vision problems can be:
- Prevented. For example, by limiting the amount of time a child spends looking at electronic devices
- Treated. For example, receiving medication for eye health problems
- Helped. For example, through using assistive products such as spectacles and/or rehabilitation.
Some vision problems are unavoidable. This means treatment will not fully restore vision. However, assistive products and a more accessible environment can assist the person to do the things they need to do.
