What are sensory impairments?
Sensory impairment is the common term used to describe:
- deafness and hearing impairment
- blindness and visual impairment/sight loss, or
An individual does not have to have full loss of a sense to be considered sensory impaired.
Blindness or visual impairment
Visual impairment or low vision is a severe reduction in vision that cannot be corrected with standard glasses or contact lenses, and reduces a person’s ability to function at certain or all tasks.
Visual impairment or low vision can be caused by a variety of conditions such as:
- genetic defects or an injury
- macular degeneration
- visual cortex disorder.
A person can be registered partially sighted or severely sight impaired, ie blind.
Many people who live with sight impairment experience different levels of sight loss. Some people are only able to determine lights or shapes, while others may experience blurred vision.
Sight impairment can cause loss of sight in the centre of the eye or no side vision. It can also cause difficulty seeing at night. It is uncommon for someone to have no vision at all even if the person is registered blind.
Eye strain and headaches are also a common side effect of living with sight impairment.
Deafness and hearing impairment
If you find it hard to hear or have a hearing aid then you have a hearing impairment.
Causes and symptoms of hearing loss
Hearing loss may be caused by a number of factors, which can include:
- old age
- exposure to noise
- birth complications
- trauma to the ear
- certain medications or toxins.
Viral infections of the inner ear can cause hearing loss to occur all of a sudden. Hearing loss can also be gradual.
Common symptoms of people with gradual hearing loss include difficulty hearing the TV or hearing a conversation in a noisy environment. People with hearing loss can commonly experience continual ringing in the ear which is caused by conditions such as tinnitus.
Deafblindness or dual sensory impairment
Deafblindness is the loss of sight and hearing to the point where your communication, mobility and ability to access information are impacted. This includes "progressive" sight and hearing loss, where your sight and hearing may deteriorate over a period of time.
Deafblindness is often also referred to as "dual sensory loss" or "dual sensory impairment".
Lots of useful information and advice can be found on the Deafblind UK website.
Living with hearing, sight or dual sensory loss
The treatments for hearing loss depend on its cause. The NHS website provides advice and information on the different treatments for hearing loss.
Consulting your GP
If you feel that your hearing is getting worse, you should make an appointment with your GP. Find your nearest GP.
Your GP will look in both ears, and may find that the problem that can be corrected at the surgery or may choose to refer you to the local Audiology Department.
Using hearing aids
Referals to the Audiology Departement are only through your GP. Audiology may suggest that you try using one or two hearing aids.
Private hearing aids
You should consult your GP before deciding to go for private hearing aids from commercial suppliers.
Consulting your GP or optician
If you have any concerns about your eye sight, or feel that your sight has deteriorated, you should always consult your GP or an optician.
You may be referred to an eye clinic or ophthalmologist (a specialist in eyes). They examine your eyes and determine if there are any possible treatments for your condition. In a lot of cases your sight could be improved simply by different glasses or cataract surgery.
If you are blind or partially sighted, a guide dog could help you to be independently mobile when out and about. The charity Guide Dogs provides both dogs to people who are blind or partially sighted, and training on how to use them.
