Types of vision problems
Pregunta
Think back to the TAP Vision assistive products module. Can you remember the common types of vision problems?
- Problemas de salud ocular como cataratas, bultos, protuberancias o enrojecimiento en el ojo o alrededores; secreciones, párpados caídos, estrabismo (ojos bizcos o que se rotan hacia dentro), pupilas de distinto tamaño o movimientos espasmódicos de los ojos.
- Distance and/or near vision problems that can be improved such as myopia, hyperopia, astigmatism or presbyopia.
- Vision problems that cannot be fully improved such as low vision or blindness.
La mayoría de las personas a las que evalúe como posibles usuarias de lupas o telescopios tendrán baja visión.
If the person has an eye health problem or a vision problem that can be improved, they may not need a magnifier or telescope as their vision problem may be treatable.
For people who have a vision problem that cannot be fully improved, there may still be some vision correction possible. This should be explored first. Low vision assistive products should only be provided after the person has had a full assessment by an eye health professional in the last 3 months.
Always check the vision screen results and refer to an eye health professional if indicated.

Eye health professional assessment
Instrucciones
Ask the person: Have you been assessed by an eye health professional in the last 3 months?
This allows you to find out if the person has been assessed by an eye health professional, and if so, what the eye health professional told them about their vision and any recommendations.
Advertencia
If the person has not seen an eye health professional in the last 3 months you should stop your assessment and refer them now. This is because prescription spectacles or medical care could improve their vision.

Central visual field loss
- El campo visual central es la zona de visión situada justo delante de una persona.
- Una persona con un campo visual central limitado no puede ver a las personas u objetos que tiene delante.
- Los telescopios no resultan adecuados para personas que tienen problemas de campo visual central.
Peripheral visual field loss
- El campo visual periférico abarca todo aquello que vemos en los bordes de nuestra zona de visión.
- Una persona con un campo visual periférico limitado sólo ve las cosas que tiene justo delante.
- Los telescopios no resultan adecuados para personas que tienen problemas de campo visual periférico.
Sensitivity to light
Hay personas que son muy sensibles a la luz brillante.
Si una persona tiene dificultades para ver bien cuando hay mucha luz o luces brillantes, puede aconsejarle que se ponga una gorra/sombrero con visera que le haga sombra a los ojos.
Instrucciones
If the person still has problems seeing in sunlight or broad daylight refer them back to an eye health professional. They may require a product with a tinted lens.
Instrucciones
Una vez que haya entendido qué problema(s) de visión tiene la persona, es importante:
